I bought a used one 2 years ago but never used it. I tried to start it the other day and the electric starter went stone dead on the second try. It did start briefly. I have 120 v up to what appears to be a rectifier inside the switch housing according to the parts list--it's about an inch square and a half inch deep with two connectors in and two connectors out. Can anyone tell me what voltage I can expect on the load side of the rectifier (if that's what it is) or at the starter motor. If there is any advice, I'd sure be glad to get some.
