Hey guys. I have an onan emerald plus 4000 generator. Was testing my new starter and hooked up the jumper cables to it wrong, frying everything. I have since replaced the starter, solenoid, and control panel. I’m getting power to the solenoid and just 0.2 volts to jumper 7 on the wiring harness if I disconnect the control board. 11 is supposed to be power in, but there’s no power there. It looks like those cables go through a ground or something first.Any ideas?

There should be a fuse on the board. You have 12 v at the solenoid what about coming out of the solenoid while pushing the start button. What solenoid did you buy it has to be the right one ?

Fuse is good. Solenoid is good. Power isn’t getting to the control board at all so switch doesn’t do anything.

Could it be the voltage regulator?

6.5NHEFA26100MIt's a Onan 4000 4.0 BG E-F/A 26100P from 1998.

Pray tell explain how reversed polarity would harm a starter motor? Even a permanent magnet gear reduction model......

B+ goes to k4 from the hot side of the solenoid and f2 is a 10 amp fuse between them.

Fuel pump runs if I bypass the control board, but no power is getting to the board.

Thanks!

I’ll got out later this afternoon and do some testing on one I have on the bench before I say anything.
I would unhook the starter so it doesn’t spin the motor when pushing the start button and start tracing power from the start solenoid with the start button pushed in and see where it goes and where it stops getting power. Tape the starter Wire up so it doesn’t short to anything. You should be able to hear fuel pump running with the start button pushed in.
