Pretty sure I figured it out. The breaker didn't blow the motor over heated. I have had that happen once before with an off brand 500watt motor run at over volted. I expect that I did it again with this one. I need to go down later and make sure it will still rev up. Something about running it on the edge of pedaling caused it to overheat. I expect it was too many amps flowing through it.

I can either go back to 24v or go to a lower amp controller. I have both laying around. I think it will have slightly more balls at 36v 25amp so tomorrow I will change it out and see what happens.
