Video hopefully explains issue better than I can.
Once in awhile it starts normally at full speed. Video shows motor speed is very slow and has thumping sound. 18V is present at Idle, DC power supply is strong, all connections are good, but volt drops to less than 1V on start up. Thinking armature maybe? From what I could tell the brushes look good. When I took motor assembly out of gear box, all looked fine - plenty of lub, no unusual gear wear, blade spins freely. Is she gone or have I got a chance?
UPDATE: I took motor out of gearbox and bench tested motor independently of gearbox. Motor now runs at full speed, but for the first couple of seconds at start up still has same issue of low voltage and thumping . Also, I found motor specs (last one).
