Keeping this short and sweet, dumb mistake on my part that if I'd been paying attention, I "probably" wouldn't have made. Recently cleaned, painted, etc, M8000 motor wouldn't run in either direction, not even when bypassing the solenoids. The key word is "painted"...
If I'd been paying attention, I would have noticed that there was no bonding strap, wire, bolt, or screw to ground the frame of the brush holder assy to the body of the motor. So painting this end is NOT a good idea...
Had to dis-assemble, scrape and sand off the paint - now the motor runs just fine. This method of assy reminds me of guys who don't run a separate ground wire to their trailers, but instead rely on the hitch ball to provide ground - in other words, not the best practice, but it is what it is, and now I know - and so do you!
Once re-assembled, THEN I put a touch-up coat of paint on the junction between the endcap and the motor body to prevent rust...
