89 fourtrax 300 2x4 no spark

Recommended Posts

New to the group,please be gentle lol.So I just purchased(traded my 73 sportster) for this 1989 Honda fourtrax 300 2wd.i got the quad with a no spark condition,thinking it would be an easy fix. I have tested the stator,pickup coil,coil,and inputs going too the CDI.so far everything has tested good.while doing all this I cleaned/repaired a few dirty connections and replaced the battery and cables.the kill switch is good and the ignition switch is also good.so I ordered 3 cdiand coil kits(because I have another Honda).Tonight I put the new CDI and coil on and tried to check for spark.No spark again.but about 5 seconds after letting loose of the starter button the CDI blew apart.what am I missing here?

No just one wire at a time with the connections.this thing had the no spark condition when I bought it,so I'm not sure what may have been done prior to my ownership of the quad.

Something sounds like you may have an electrical or wiring issue. I imagine it blew apart because of exceeding the maximum voltage.

I think over voltage is correct but I cannot figure out why.j have tested the wires going into the CDI and nothing exceeds battery voltage.

And yes I have checked the stator magnets and the piece on the outside of the flywheel that triggers the pickup coil.also hooked a test light to the bl/y wire from the pickup coil and the light pulsed while cranking.

Just to add more info.the previous owner stated he was riding the quad and it died.had it pulled home and began to diagnose it.the guy didn't have the proper equipment to do this so he removed the stator cover and took it to a shop for diagnosis.shop told him he had a bad stator,and tried to sell him a stator.when I got the quad I ordered a stator CDI and coil.both stators ohm correct as with the pickup/trigger coils.

Removed wire harness last night and took sheathing off.was very wet inside the sheathing,so today when I get a break I am going to look at all the multi joint connectors,to see if I can see corrosion or oxidation.

this might be a stupid question is the kill switch in the exact middle. on my 88 trx the vehicle will still crank just no spark if it is not.

I think I may have found the problem.i have a bl,gr,and Rd wire going to the rectifier.the black wire(if I remember correctly) did not have 12v.

If that is right then the voltage stops at the rectifier.

So I can verify the:green(ground)

Red(constant possitive)

Black(switched possitive)

On the rectifier are good,however no continuity on the yellow wires from the other side of the rectifier.they also do not short too ground.could this be the issue?

IT RUNS!!!!! Like crap,but it makes spark and starts. The issue was the CDI,and the new one I ordered from eBay was the wrong one DC I think.went to a local bike shop explained the issue and showed the box from eBay,and he immediately told me I had the wrong CDI unit.thank you fellas for all the help and input.

      How are you doing guys I just joined I have a 1998 Suzuki King quad I’m having problems with high RPMs the ATV idols perfectly but soon as a throttle up it doesn’t stall but it just bogs down it has no power any suggestions thanks

      My 2014 750 king quad stalls sometimes when I touch or turn the handlebars,the problem has gotten worse,my machine has 475 miles and is only trail ridden,I have a new factory battery and i have 14.2 volts when the quad is running and 13.3 on the battery when not running,also using a multimeter there is no change in volts when turning the bars until it does stall,If I pull the 40 amp power steering fuse it will not stall.......I've been told its the ECU,Hate to buy one if thats not the problem,but its kinda leaning towards that,,,,,need some opinions.

      Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light  on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.
