Husky compressor runs with no load
by Peter Coates
This is a husky 5hp vt631502aj portable. I've used it in the garage for a couple of years without problems, but now when I turn it on, it tries to start, hums for a couple of seconds and then blows the breaker.
With the belt off, the motor runs freely without blowing. The pump turns easily enough by hand too, but the motor won't quite drive it. It always ran like a truck before--this started suddenly.
I'm not sure how much resistance I should feel when turning the pump flywheel by hand--it turns, but it's not like spinning a bicycle wheel--you have to apply some pressure.
