RT ENGINE HAS NO SPARK.. CKED STATOR 2.8 VOLTS PEAK COMING OUT... LEFT ENGINE 2.7 VOLTS PEAK...CKED FUSES AND FOUND THEM ALL MESSED UP .. INSTALLED ALL NEW FUSES .. DID VOLTAGE DROP ACROSS THE MEPM GROUNDS ALL WITHIN .01 DROP..CKED START STOP SWITCHES BY SWITCHING THEM THEY ARE OK.. Did get the rt motor to run for a short time thought had it wiped.. but after 2 or so hrs sitting came back to it and again no spark on rt engine.. before I condem the MEPM does anyone know what I may have over looked and is there a rebuild for these MEPM'S..
 
I just had to replace my mpem on my 98 speedster. Was doing about the same thing. I've heard about people removing the black potting and repairing the board but it's hard to know if it can be done. We removed my potting just for kicks but mine was smoked! New mpem will run you 1500$ I can try and find the link where I got it and send it to you.
