9920 too hot

[Scott711]

Well I got back after it this morning and see nothing wrong with the esc. The pcb and all its components look clean and undamaged. So I hooked up the batts and took it for another spin to see if the magic elf fixed it over night. No luck, after a couple of spins up and down the street she was glitching again and getting hot. The thing is it is hot at the spot where the negative lead terminates to the pcb and that capacitor is also heating up pretty fast. The heat sink and rest of the esc are in the 60's on the heat gun.

I've got another problem that has come to light. The motor is making a sound like gears striping. When I put my foot in front of the truck and hit the gas I get no power to the wheels just an awful gear striping sound and it definitely is not in the tranny or drive-line. I get my ear down there and it's coming from the motor. At first I thought the pinion was striped or something but the shaft showed no signs of that. So I've taken the motor off and give the shaft a good spin and it spins real clean feeling no weired grinding feeling or anything. I don't see anyway to get a look at the inside of the motor so I'm not sure what to try next. Is it possible there is a short inside the motor?

Btw, I'm using a UBEC and standard size tires nothing monster anything like that.

DesMoines, WA is a small suburb 10 miles south of Seattle.

I may have found the culprit. It appears one of the motor leads has cracked or peeled away the casing and exposed wires and possibly grounding to the can. What do you think. Can it be fixed? Do you think this is the problem?
