getting my granddaughters honda 2007 trx90 ac running again after sitting for 9 years. took care of the fuel system and am learning as I trouble shoot the electrical system. have two issues that may or may not be related. neutral indicator light does not come on. checked lamp, connections and replaced neutral safety switch. still not on. second issue is sometimes it will not fire. just dead. give it a little push and drop it in gear, return to neutral and try again, fires up no problem. have replaced battery, neutral safety switch, ignition module, plug and starter relay, rectifier is working and ignition switch(key) and starting button both are working as should be. was thinking maybe the contact plate under the NSS is worn or bad. any input would be greatly appreciated.

I agree and chances are it's a loose wire or bad connection (rust, etc) somewhere stopping it from making the right contact. I would look over all wires closely for "mice" damage via chewing on wires as well....

It sounds like the negative battery cable is not cleanly grounded where it bolts down onto the motor. There may also be a poor ground cable or ground wire (near the CDI?) connection on the frame. Assuming rodents haven't chewed up the wiring...?

Welcome to the forums!

Attached an image showing where the frame grounds are located next to the CDI.

You can find a copy of the service manual HERE in case you don't have one yet.

Let us know how it goes for ya.
