I got a new inverter for my Powermatic 3520A. Got the parameters to plug into the inverter but every time I put something in it reads error??? Had this problem for 2 years now. Would really appreciate some help with this. Best would be someone in Wis that could come over and look at this. I live in St. Germain and would pay to have someone come over and fix this. All I have now is a 900# boat anchor, help.
