groped 750 esr Motor help

Post by Edd173 » Jun 08 2019 5:08pm

I’m new here
I hope someone can help.
I just fitted new brushes to my groped 750 esr. I also sanded down the copper commutator with 600 grit on a lathe to get all the pitting out, as the engine previously overheated and seized .
Now it won’t spin at all. It just clicks and heats up when I put the power on. Can anyone suggest any help?
