So we bought a used 96' Speedster, boat ran fine at first until the batteries died and had to be replaced. Replaced the batteries and the 5AMP fuse on the MPEM starts to blow. At the advice of our dealership we send the MPEM off to be repaired, someone named mike, think he used to be a member here. 2 weeks later we get the MPEM back Fedex, return to sender. I guess Mike just dropped off the face of the earth according to what I've seen here. So my wife takes our MPEM to work, she works for a chemical company here in phx, and goes about removing the potting from the MPEM so we can take a crack at it. We check all the diodes and they are all fine. So at the advice of our dealer we spent all this time trying to fix a problem they were 100% sure was the cause. Now we are back to square one I guess, anyone have any suggestions?
