Hey guys just a quick question just bought a boat from a guy and took it out twice ran sort of well except for the tachometer on the left engine only kicks in at about 2000 or 3,000 RPMs. Anyway was doing some maintenance tonight and just happened to notice that the ground wire from the MPEM was not connected to the battery. Goodness have caused any performance issues or damage to the MPEM?
