Well, tragedy struck today while mowing. I was so happy with the new setup and thought it was going great. However, the motor had some problems and I had to push it back to the garage to inspect it. This is what I found:
Here is one side of the armature.
Here is the opposite side.
My guess is it still got too hot and ended up melting some of the armature wires. So, I'll have to look into rebuilding it, or replacing it.
I have an email off to a few guys in the EV club to see what they think.
