im bringing this back to life, as i am working on this type of setup. my welder/generator had 9 capacitors hooked together they were 60uf each. a bunch were bad when i got it( free) and the guy had thrown out the bad ones. is there a way to check that im going to be able to get output from this before spending the money on new capacitors? (need 4) right now without the capacitors i show no voltage anywhere in the system
