2003 Honda 400EX neutral light inop

Recommended Posts

Starting to put my Ex back together since i got the motor back. Most of its together.

Everyone who reads this I have attached a copy of the electrical diagram so you can play along.

I reinstalled the wiring harness. The only modification I did to that harness was to bypass the clutch switch so it will start with out the clutch lever. I have high beams, low beams and taillight. I can also hear the starter relay click when I hit the start button. I verified that the starter will turn. I can only do it VERY briefly as there is NO OIL in the motor. I just held the button for a split second, probably faster than that. The starter did engage.

What i dont have is the neutral indicator light. I verified that the indicater light does work when 12v is applied to it. I am unsure of the condition of the diode inline with the neutral light. I only have a Powerprobe. If you dont know what that is google it. Its very handy.

I did verify that I have 12v at each terminal on of the light (Black wire and Light green with a red tracer) whcih really puzzled me. :aargh: that leads me to believe that its the diode. I also verified that the neutral switch itself does work (physically and electrically) and I see the neutral arm move inside the motor when I shift to neutral. I didnt try to press the switch with it hooked up to see if i get a light.

I cant verify anything because I cant start the quad yet so Im guessing right now. I dont think that this problem will prevent the quad from running. The neutral light harness does go into the regulator which worries me. I would rather the light works as I dont want to chase problems later on. :realmad:

Looking at the diagram what am I missing?????? :aargh:

Verified diode is ok. Now what? I checked all connections and made sure all connections where properly color coded. A couple where iffy but seem correct. Will recheck in the a.m. Tomorrow all the plastics go on, fresh 94 octane in the tank, a recheck of all connections and fasteners, then oil and prime the motor. Then gets dropped off at Diggin for the breakin, test and tune. Maybe he knows whats with the light.

Quad is primed and all set for engine breakin. Neutral light works now. Went through all the wiring again. Maybe a connector wasnt pushed in fully. Not sure :-)

In a couple of days she will be trail worthy again!

      recently picked up some project bikes off CL for cheap.  got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start)  plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
      so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows.  things I see:  carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.

      I posted earlier looking for a wiring diagram, but maybe someone can help me with the problem if they’ve had it before. 
       
      The quad Will start and idle ok, when I open the throttle it will rev all the way up until WOT and then it dies back down to idle, and if I keep the throttle wide open it will rev back up. It will do this over and over and over. 
       
      I replaced the carb, (twice), Rectifier, battery, and spark plug.  The Stator ohmed out to the proper specs from dinli.  The other issue i can see is I’m not getting 12v on the choke circuit. The lights don’t work either. 
       
      possible bad key switch? Maybe the new rectifier is bad? All the contacts on the key switch also ohm out properly    
      comprsssion is up to 125 psi and spark is there. 
       
      Reed valves look great.....
       
      im at a loss. Any trouble shooting advice would be appreciated.

      Anyone have a legible service manual for a Dinli diamond back 50cc? The one on Dinli’s website is a scanned in copy and the wiring diagram is totally unreadable. Got some issues I can’t seem to figure out. I think that Polaris used the same platform these years 2001 ish?
       
      any and all help would be appreciated

      I recently acquired a Yamaha bear tracker 250 that does have a wiring harness.  Does anybody have a wiring diagram for the 250s. Also if you have a pin diagram that tells be the colors of the wires going to the cdi and rectifier or just a picture of the plugs would be much appreciated. I can’t find anything on the harness online. I have all of the switches and stuff and I plan on just build a harness myself because I can’t find one to buy.

      Hey guys, any ideas would be greatly appreciated on this. 
      So it started a few months ago, riding with some buddies and my 400ex all of a sudden lost power. Wouldn't fire, wouldn't sputter. Towed it home, and then it fired right up. It continued this pattern for a week or two, ran perfectly for varying amounts of time, suddenly died, and would start right back up if I waited 20 mins or so.
      Now we get to the next phase... I was dinking with it one day, I think I pulled the carb off and cleaned it out, (not really dirty but just to be sure) and I was trying different fuel screw adjustments. At any rate, I didn't notice much change, except obviously running a little poorer when I had the fuel screw in the wrong place. I took it on a quick ride around the block, and it was just fine. Ran awesome, had lots of power, etc. Then went around the block again and it died on me this time right as I revved it. Ever since then I haven't been able to get it to start. 
      Now when I turn it over, it sputters, fires a touch, but won't start. Ever. I replaced the plug, CDI, and coil, with no change. I do know that it has spark, but I don't know for certain that its big enough. After replacing these with no change I popped the carb off and tried firing it up spraying some either right into the intake. Upon doing so, it revved right up, but obviously there was no carb so it didn't stay running for long. While spraying the ether it seemed to run just like other engines I've tried spraying ether into no popping or backfiring etc. When it fired right up on the ether, I figured I must have a carb issue, so I just bought a whole new carb instead of taking the old one apart for the 800th time. When I put it in, there was no change whatsoever. Still turns over and sputters, but won't fire up.
      I am completely befused, and any input would be graciously accepted. If you read through all that your a trooper, so thanks very much :)

      I need a motor but i really dont hsve lots of cash and im on the kenai peninsula. Up here in Alaska i really need help

      I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE.
      when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out 
       
      Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
      When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
      If my bottom end is blow why would it still turn over fine,
      Are my valves siezed or not working properly 
      or is my timing off causeing valves to not open in correct order with fire 
      PLEASE HELP all help is appreciated

      I loosened the allen bolts on the carrier and when I went to put my driver in the alot to pull back and tighten the chain, I noticed the holes were facing the front of the bike. I tried to slide a driver in and tighten the chain but the thing would not budge. I nearly ripped the tip off the driver in the slot. Any suggestions? 


    • By afa913
      Am i better off to just replace the bearings or buy the whole carrier?
