Sanborn motor starts fine but bogs down
Its ,3hp Sanborn compressor. Pump head works fine.
Take belt of motor and motor runs fine.
Put belt on (not over tight) flip the switch and motor starts running get up to about 10-15 lbs pressure and motor starts to bog down and then stops due to thermal switch popping.
Is this a capacitor problem? Start/run or is motor just junk?
