  • / New rectifier and switch/MM275 wont start/trips circuit breaker
Hi. I have a three year old B and D electric corded lawn mower MM275 that wont start. I replaced the rectifier and it ran for a while and stopped. I tried another and it did the same thing. I got a new switch and rectifier and now it trips the circuit breaker. I'm sure everythings wired right. This started after I ran over a part of a tree branch I didn't see. Everything inside looks and smells OK. The blade turns by hand with no problem. Is the motor shot and I need a new mower? Thanks for any advice.

Recheck wiring, blade & or motor shaft bent, parts binding while spinning motor, motor brushes?
