M35A2 not starting

[Brew]

My M35A2 will not start. I’ve got 23v at battery. When I turn on accessory, all gauges work and low air alarm sounds. Hit start and nothing. I changed horn solenoid but didn’t have new horn button to test solenoid. After horn button install, nothing, checked horn and found solenoid burned up. Could I have crossed the wires? I’m at a loss.

Your batteries are a bit low to begin with. I would start by charging and load testing your batteries first.
Welcome to the site by the way.

Those starter buttons are kind of finicky at times as well. You might try a jumper wire to exclude it.

As was stated on the first post be sure to load test those batteries, that has been the biggest battery problem I have had over all these years, now if I have a problem and voltage looks OK I load test, saves a LOT of time!

If the load test is low, does that mean I need a new battery?
