I've acquired a 87 trx250 fourtrax, put a new charged battery in it and have no power when I turn the key. None of the lights come on including the headlight. Any suggestions would be great. Looked over the wiring to make sure I had no broken or cut wires and they all look good......

Chaeked the fuses up front and one by the battery, they're all good....still not working. I'm stumped, all the wires are good nothing visibly wrong and battery is charged:(

Is there someplace to download the wire schematic or a troubleshooting sheet?
odds are, you missed a fuse ?, or your battery is not grounded ?, ignition switch not getting power in or out ?. a 12 volt test light, start tracing from the battery forward :).

and I am not sure you will find a service manual here or not ?, that's a old girl, and not many around here these days to warrant it, you can check the manual section, and see if its there ? :).

Here ya go:
85-87 TRX250 Factory Service Manual

The wiring diagram is in the back. Next thing for you to check is the Ignition switch. You'll need a multimeter to check for continuity between wires in the ignition switch connector plug as the manual shows. You can use a test light rather than a meter, if you are handy with one...

Let us know how it goes if ya can...

Thanks for all the info, found my issue. My ignition switch was coming apart, pushed it back together and the oil and neutral light come on. Starter button also works, guess my next investment is a new switch ????Thanks again

Great, thanks for letting us know!!!

You can still buy those ignition switches new:
35100-HA8-682 SWITCH

May have to search the part number to find a better deal, or find a used one with keys on the fLeebay... don't waste your money on any non-OEM china made parts and you'll be good to go.

I had a similar issue, I ended up spraying WD40 in the ignition barrel, walked away, tried it the following morning and it worked. When I checked it out that day, all the plastic on the bottom of the barrel had gone brittle with age.
