I'm looking for a MPEM for my 1995 sportster. P/N 278-000-571. I did the idiotic move of using a battery starter to jump my boat after a top end rebuild. Engine started up right away and ran great on the trailer. put it in the water to do the break-in and got 200 yards from the dock and it DIED. Now I have nothing. No power to the ignition system at all. I can jump the solenoid and the starter engages, engine is free. Any input or leads to a part is appreciated. I have the new diode to repair my MPEM, but am impatient to get this thing back on the water. I will use the colder months to repair and have a spare.
