I have an ’87 350 TRX. The last time I used it everything was fine, took it on sum trails n had no problems. I trailered it home, backed it off the trailer, n shut it off. Next day I go to start it n there was NO power to ANYTHING. No lights, no fuel pump ticking, no neutral indicator light….nothing. The battery is fine, all of the fuses are fine, and I can’t see anything else out of place or disconnected. Any ideas? Thanks!
