I picked this thing up for next to nothing replaced the cdi box after i got it running now the neutral light wont got off when in gear and the key no longer kills the motor can the cei box have something to do with this

Good question

the 86 and 87 Fourtrax require a model specific CDI. The 87 Foreman has its own CDI. The 88-93 Foreman have their own as well. So If you bought a CDI for the wrong model or an aftermarket CDI yes this could cause problems

Was it running when you bought it?

 

[pantera51]

Not when i picked it up had to clean her up some got her goin rode it around my yard after awhile it would die when i put it in gear let it set for a few min and it qould be fine for a lil bit then act up again

If you can get it running with regularity I would say the old CDI is ok and would put the old CDI back in and try some of the following.

Click my link to download the service manual. Good troubleshooting diagnostics in there

There’s a lot to check on an unknown machine.
Does your oil light come on momentarily and then go out when you turn ignition on? Oil temp sensor or fan control. Not likely if you only ran it a bit.

Test to see if the engine note changes when you click the choke off and on. The starter valve could be worn and not seating properly—so your choke is always on. That’s where I think you should start

Do you get a buzzing noise when it dies? Then could be fuel pump is not getting any fuel to pump or the pump is not working. I don’t think that’s it though.

Brand new carb oil light does come on pumps good getting plenty of fuel

 

[Goober]

Hmmm I like the OEM carb better—still got it?

You didn’t answer my question about the choke.

 

[pantera51]

Unfortunately i dont have stock carb but yea the choke does make a diff when its running i have to choke it for it to stop running aftwr key is off

wrong ignition switch ?, ignition not wired right ?. neutral switch bad.

 

[Goober]

Can you kill it wth the kill switch?

Also You didn’t answer my question about the CDI. Is it possible you bought an 86-89 CDI?

China CDI? If so, don't start the motor again, cause you'll probably be seeing smoke coming from expensive places.

 

[pantera51]

Ill put the old one back on and see what happens

 

[pantera51]

I'll put the old cdi back in and see what happens when I richen up the fuel mixture what all would the cdi box mess up we talkin stator and trigger coil regular I'm just curious

 

[retro]

The Stock OEM CDI will not cause any harm to other components. A china CDI... extremely high risk, if it even works right at all, for a few minutes. Just don't ever do that and you got nothing to worry about.

 

[Goober]

The original CDI could be bad but it will be easier to further diagnose.

 

[pantera51]

True just not sure where to go when it acts up

 

[Duck0fDeath]

Divide and conquer. Next time it dies and wont immediately start back up check for spark. The answer to that will tell us whether it's electrical or fuel related.

 

[pantera51]

Put the stock cdi back in reset the carb runs great no on to fixing the front drive shaft or front diff

 

[retro]

Thanks for letting us know! You got awfully lucky, there should have been smoke rising the moment you plugged that china CDI in. China ignition coils smoke OEM CDIs too, in case you ever think about trying that stunt. You already know china carbs and fuel pumps are junk... only the wealthiest of wealthy folks can afford to buy china parts. LOL

 

[pantera51]

Yea put it up on stands to check front end front not spinning when in gear can spin front tires and can hear a clicking in the drive line gonna pull it down here soon
