i have another thread for the same question.

I would test the 2 large contacts on top of the start solenoid with an ohmmeter without power applied. If they are shorted or show a resistance then the solenoid is bad. If that shows an open circuit, Then without power applied test the start button and the wires that connect it to the MPEM to see if that is shorted out. If that is ok then disconnect the control input at the base of the start solenoid (probably a white wire) to see if the MPEM is constantly energizing the solenoid when power is applied.

So it’s currently on a lift and not easy to work on. When I unplug the yellow/red and black wire from the solenoid it isn’t letting power go to the starter any more

I think you still need to test the start button and the wires connecting it to the MPEM for a short that could cause the MPEM to constantly engage the starter.

Yeah I’m going to I just got it off the lift on Sunday and back to my house today so now I can work on it easier

The other day I had unplugged the stator to make getting mpem apart easier. Hopefully this makes more sense to you.


when I unplug the stator with all fuses in and touch the big ground wire to the battery the starter doesn’t spin. But when I touch the little one to the battery the solenoid clicks.

When I pulled the 15 amp fuse out of the mpem with the statue plugged in touching the big wire to ground spun the starter and touching the little one to ground made the solenoid click.

When I pulled the 5 amp fuse out it killed all power.

When I tested the starter button I got open loop.

Also when I touch the small wire to ground the trim is working but the gauges aren’t.
I’m thinking the mpem is fried and since this is a freshly rebuilt engine from a local guy. So Idn if the stator is a cheap one and fried the mpem.

I ran out of day light at that point.
