Bayou 220 no power at ign. switch or coil, lights etc

Recommended Posts

I recently bought a used 220 They said needs carb work, ran fine when parked (4 years ago)

After looking at it. I have no power at ign. switch or coil, lights etc. Have power at starter relay which I can jump and it cranks

but of course no spark. Is there a fuse I am missing? Found one under steering wheel, 2 wires connected to it which aren't there anymore. 

Battery fully charged just no power anywhere that I can see. Need ideas where to start.

Look under the seat where the battery is. You will find a round relay. NOT the starter relay. Another one with four wires going to it.  One brown one green and two black.  Take a piece of wire and jump the green wire to ground and turn the ignition on and see if you have dash lights and able to crank the bike.   Make sure the bike is in neutral !

There is a fuse right next to the starter relay.  Def a good place to look first.

Ok, No fuse found anywhere. Power to starter relay, nothing coming out of any of the wires except the 2 you can jump. Is

this also a fuse combo relay? 

Next I ran a fused jumper wire from Pos/Batt. to Single white wire not connected to anything by battery and get power

back to combo starter/relay. Got power at key switch still no power at Pos. Ign. coil or Neg coil Does the relay/fuse have to be 

good to get power at coil? 

Next Still jumpered I disconnected kill switch still no power at coil. 

Last question The white wire on pic 3 is what I jumpered 12v to.

that one and the one next to it are not plugged to anything. Are they supposed to be plugged in or are they both

test connectors?

Ok Update. I was taking the starter relay off and found the 30 amp fuse under the cover when you unplug it. 

It was blown. I replaced it and no crank. Grounded the green wire on the other relay which you said to try still 

no crank. I unplugged the kill switch and jumped the starter relay and it started for a second. I was only using 

starting fluid. Now I know it will run. Why wont it crank at the switch? Starter relay bad? its in neutral. Also any

ideas on the other wires not plugged in I showed in pic 3 white wire and black/yellow and the 2 unconnected wires

under the steering wheel?  Thanks in advance Az

The round aluminum type relay is the starter circuit relay. It’s a lock out relay that allows the starter circuit to close. It’s connected to the neutral safety switch.   Ok try this.  Put everything back the way it needs to be and jump the two black wires on that starter relay.   It has a green brown and two blacks.  Jump the two blacks and try and hit the start button.

Any luck ?

What is that on the dash? Is that a home made ignition?  The bayou should have the ignition on the right side plastic in front if the gas tank? If that’s home made then you have to look back at the wiring diagram to see what was eliminated and how it’s wired.

That picture is your start circuit relay inside that black rubber boot.   The wires going onto it are as follows. The green wire comes from your neutral/reverse safety switch.  When the bike is in neutral that wires gets grounded by a device inside the left engine cover by the shifter.  The brown wire comes from your 12v positive and should show 12v+ with the ignition on.   The two black wires are what completes the ignition circuit allowing the dash lights to come on as well as allow the ignition button to run the starter.  

So if your handy with a tester make sure the brown wire has 12+. Make sure the green wire has continuity from green to ground when the bike is in neutral. 

If you don’t have 12+ on the brown wire try a jumper from battery to that brown. 

Also the green wire should be providing the ground for the relay. Hence the continuity test.

lastly you should hear or feel a click from that relay, what that does is makes contact for the two black wires going into that relay.  If you have all the above power and no click then the relay is bad. You can jump the two black wires and see if the dash and start button works.

Ign switch is ok, just removed it out of the cowling to access wiring better. 

Jumped the 2 blacks like you said still no crank. Thanks for the info on starter circuit

I am kinda handy with meters was in auto repair for 23 yrs but 1st atv and kinda rusty at it. 

Have to wait till next day off to mess with it. Any info on the wires that are disconnected?

Thanks. Az

Those two wires look like they were wired for an auxiliary of some sort.   What is that item on the dash? Is it a cigarette lighter ? If so then there should be a positive and negative on it.   

Unless I’m not sure what wires your talking about.

Having same problem on a kef300a. Only sparks twice. Once as soon as you touch start and once when you let go. Turns over as long as you hold button. And I don't have the 4wire relay only have 2 wire starter solenoid/relay?

Welcome to Quadcrazy @Jay C. There should be a second relay in a black rubber boot someplace on the bike. I will look at your diagram to verify.  It may be a completely different problem. In the mean time you should start a new topic about your bike and include the make and year of your bike and the problem so it can be tracked better. A lot of  new members I’m noticing have been  adding there bike/problem into existing topics and they get lost.

No cigarette lighter just a hole with a cover on it. Under  it has 2 wires. 1 is fused and both are cut and disconnected. 

What about the white wire and black wire with yellow stripe by the starter relay in pic 3.  are they supposed to be connected anywhere or are they test leads? 

After checking what you said I will start a new topic on it. I found out yesterday it is a 1995 model Bayou 220 Thanks

Those two wires don’t  go anywhere. On my bike they were neatly tied up onto the harness. I’m assuming an auxiliary connection.  If you look at the black with yellow stripe you will see there is one of the same going to the ground terminal on the battery.  The white when I tested it gets 12v when the key is on.

      Hey guys, new here, but haven't found ANY answer to my specific problem on a Suzuki dedicated ATV forum, so here's to hoping!
      I acquired a 95' Quadrunner 250, 4x4, (LT4WD) for practically nothing with no spark. The PO had tossed in a used stator which didn't fix the problem... so I went all routes (though cheaply) to narrow down the initial problem of no spark. 
      Plug, coil, CDI (caltric) and stator w/pickup (caltric) were purchased and installed. And it RAN, but bogged horribly and would not rev past 1/4 throttle. 
      I checked fuel flow, vacuum lines, all the normal stuff, no issues. I decided to check the valves and cam... well, there was one problem. The cam was 1mm under the lowest spec in the manual. So, in-came a new cam, Stage 1 Hotcams... also threw in a new set of shindy valves, lapped them, replaced the valve seals, and the timing chain. 
      Back together again (w/stock airbox and new oiled filter). Now it idles even better, still boggs at 1/4 throttle, but will rev past it if you hold the throttle open for a second. Ahaha... success!
      So I was able to ride it above 1/4 throttle once I had momentum... could shift through the gears, all was good as long as I kept it over 1/2 throttle. Took a long enough ride to break in the cam properly at least so I won't have to worry about that. 
      Now, I start fiddling with the carb. It's clean as a whistle, stock, with stock jets (new replacement Mikuni jets). Same problem. 
       
      I start thinking, maybe this is fuel related and the bike is having an issue transitioning from idle jet to main jet... so I LOWER the needle by raising the clip 1 spot. Now it revvs up in neutral with no bog, but it boggs about the same trying to ride it. So I move the needle down again with the clip on the top slot. Better, but still has a bit of bog at 1/4 throttle. 
      The last bit of advice I got was to ditch the CV carb... so I sprung for a brand new Mikuni VM30-83 round-slide. Bolted it up, blew into the vacuum tube to fill it with fuel (no vacuum port on this one) and she fired right up... but there is still a bit of bog, it's just masked by the fact that I'm not waiting for the vacuum diaphragm to open. 
       
      So I feel like each little step brings me closer, but not perfect. I'm now wondering if this is still in-fact a carb tuning issue (I have some jets I can fiddle with and maybe lean-out the idle jet a little.) OR if the cheap-a** Caltric Stator/Pickup is what's causing these issues. 
       
      I have a 95' KingQuad with 400 miles on it... like new.. runs like a top... I've tried both the stock QR and the Caltric CDI boxes on it, and it revvs up and runs like a champ. 
       
      The only unknowns between the two systems are the carb, and the stator/pickup. My next step in troubleshooting is to rip apart the King Quad and test it's CDI on the Quadrunner... but considering there is no change to how it runs I doubt it will lead to a solution. 
       
      HOWEVER... I tried the stock CDI just recently after running the Caltric this whole time, and the bike runs like garbage. Hardly idles, and won't rev up at all. So, that is my one smoking gun telling me that it's either the pickup coil or the stator itself. 
       
      Has anyone had a problem even CLOSE to this? I can't image the carb would be causing this many issues, especially going to 2 different ones, both with stock jetting to OEM, and exhibiting the identical symptoms... the only change is when different CDI's are plugged in, or when the needle valve leans out the mixture. 
      Also, I checked the piston, rings and bore when I had it apart and they're like-new... no scoring, rings are loose, cylinder is still round and has honing marks still int he bore. Stock piston, stock bore size and it has 160psi compression. Battery is brand new, and I've tried 3 different R/R's, none of which change any symptoms, but slightly vary the charging voltage by .2-.5 of a volt depending on which unit. Also tried a new coil which changed nothing. 
      ANY help would be appreciated. Too much invested to not get it running right.

      Hi. When I press the starter switch, the solenoid clicks and the starter doesn't turn. The battery is good (about 12.6 volts).  I tried shorting the two big bolts on the solenoid with a screwdriver.  I got sparks and the starter didn't turn.  I tried running a booster cable directly to the starter post but all I get is a bunch of sparks.  I connected the positive side of the battery to the post or bolt on the starter.  I connected the negative side of the battery to the frame,  Did I connect everything wrong?  I don't know why I get the sparks.
      Thank you

      i ordered a keihin carb for my 07 trx 90 and it fits nicely but the new cable they sent is way too long and i can't make it work.  the old honda cable cap [that fits on top of the carb] is too small to fit.  the keihin cap is approx 3/4 or 19mm.  honda cap is more like 1/2 in.  the keihin has a rubber boot on the cap where the throttle cable goes through . i don't know how to find the right length [most cites don't give the length].  i'm not sure how cables fit into that boot  and do i need to add the length of the boot to the cable?  the old honda cable is 28 inches total, but the cable movement is only approx 2'' which would not be enough to reach the actuator block on the keihin.  looking to find a throttle cable compatible with the keihin.  any help, please.

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      Hello all, wanted to sign up for this site as I am sure I will have lots of questions soon. One of my coworkers has given me a free Bayou 220 that does not run, I was told it needs a new wiring harness, however I cannot confirm any of that yet.

      Next weekend I am going to drive up to the place and pick it up and get some hands on but right now trying to find some service manuals so that I can trace and find out what is going on. My plan is if I can get it to run to do a full restoration and use it to putt around the trails around my house.

      I have some experience with small engines, currently have six mini bikes and a buggy with a GY6 motor that I brought back to life and I am hoping I can do that same with this. Really hoping the Bayou has good compression and it's only a electrical problem.

      In the mean time I am going to be reading this forum to learn as much as I can and hopefully find a service manual. I have attached the only pic I have of it so far.

      Thanks!
      Daniel
