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 !

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?




This is under the steering wheel. both wires cut. What are they supposed to go to? Cig. lighter?

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.

      I HAVE a 2002 big bear 400 4x4. I have two wires atacking to the front of the carb. What are they for?
    • By stinky
      I have an Outlaw 110 that will struggle to turn the engine over. Jump starting doesn't help other than the battery will drain LONG before the bike eventually starts, so is required. If you keep messing with it long enough it will eventually magically begin to crank fine and sometimes finally start. Once we finally get the bike to start and warm it up thoroughly, it will turn over and start just fine the rest of the day like nothing ever happened... next day it won't turn over again.  Internet research has found lots of people saying they replaced starters, starter clutch, wiring, etc. but with only about 50/50 success rate for their particular problems... and I never found anybody describing a problem like mine, so I'm looking for advice/experience. Would rather not just start blindly throwing parts at it. Does anybody have any thoughts/ideas?

      Thought i would share a fix that I came across. I was working on a 99 scambler 500, The customer complaint was that even with the fuel shut off the tank would slowly drain out onto the ground. First I found the fuel shut off was bad/ leaking/ dripping so I installed a new one thinking that would fix it. Then I ran it and and seen that the overflow was flowing fuel out from the bowl. So I cleaned the needle and seat and changed the float height to lower the fuel level in the bowl. Well... It still overflowed and flooded. So I bench tested the needle and seat with a pop off tester. I found that these newer style needle and seats just utilize an o-ring to install the brass seat into the carb.
      The o-ring for the seat had hardened up allowing fuel into the float bowl from under the seat. New o-ring and problems solved.

      Hi guys.  First post, hope you can help.  As above 1991 Honda fourtrax.  Starting, running fine until a few weeks ago. Used primarily to put my ski boat in the garage (put 2" ball on front).  Any way, had just backed boat into garage, turned off to crank trailer wheel down, when I went to restart got nothing.  
      No neutral light, no headlights, no reverse light, would not turn over when start button pushed.  It would crank and run when I jumped the contacts on the start relay.  While running the neutral light will come on, although it is dim and flickers.  Reverse light on when running and in reverse.
      What I have done to this point:
      1.  Used jumper cable to ground battery (-) terminal to engine block thinking ground wire from battery to engine may be bad.  No neutral light, no start.
      2. Applied 12 volts to start relay.  Got a loud click like it was making contact.  I didn't have the battery/starter cables connected to the relay, but I am assuming it would have cranked at that time.  
      3. Disconnected neutral switch wire.  Grounded neutral switch wire with jumper wire. No neutral light, no electric start. 
      At this point I am thinking ignition switch vs broken wire in the harness going to the neutral switch (due to dimness and flickering when running).
      Any and all suggestions to help track down this issue are appreciated.

      Let me start with I have about 30 years of ATC experience, but not much with stuff made after 1988.  Some, but I'm mechanically inclined so it's all good.  I"m rehabbing a 1997 Bayou 220 to send back into the wild and the mechanicals are now all good, just working on making the electrical system...electric.  Right now, I have no power on the white wire as tested directly on the plug at the starter solenoid.  I'm assuming that wire is supposed to be hot any time it's attached to a battery?  The genius that had it before snipped a couple wires and inserted a fairly heavy push button for electric start bypassing the electrical system. I think i've corrected everything north of the solenoid but the white wire has me stumped.  Is my assumption that this should always be hot with a hot battery correct?  Does this indicate a broken circuit in the starter solenoid?  Relay was also bad and wired incorrectly, but that's resolved and I can make the relay click bypassing the solenoid and connector, directly giving the white wire 12V.  Thoughts?

       Bayou300 acts like it's flooding if it's it's in the Alabama sun all day but, I've cleaned the carb. Sometimes it'll backfire even though the timing and valve lash are in spec. Thought it was sticking float but after 2 times cleaning the carb I'm lost. So

      Bought brand new petcock and carbetator, turned air fuel needle out 2 turns and machine still acts like its starving 4 fuel on top end. Any ideas?
    • By mike costa
      Motor starts right up, but when I open it up past quarter throttle it bogs way down while ridding, the longer it runs the worse it gets. If I just leave it in neutral and  give it full throttle it revs up and down. 
      Back history:
      Bike sat for 3 years,
      Installed new plug, cleaned the fuel tank, took it to a shop and had the carburetor gone though.
      Picked up from shop, motor bogged down first day and barely got me back to the truck an 1 mph.
      Took back to shop after a month I was told it had a bad plug, I told him I just replaced it.
      Got quad home and it is doing the same thing!!!!!!!!! 
      Thanks in advance for your support!
      The carburetor has recently been gone through by a shop
