kweezinarts Posted March 20, 2010 Report Posted March 20, 2010 i have stock 90 amp alt, got my new md2d today and installed it. but before i even powered it up when i started my car i got a CEL and Low RPM's. so i meter voltage at battery only to see around 14v instead of the normal 14.4+ rmp so low i cant even drive to advance auto around the corner to check CEL. i check all wires i touched but everything looks ok. actually it was just an amp swap so everything was already in place and workin just prior. only dif is new amp and 150A circuit breaker. it seems to be messin up my ecu cuz when i rev it takes over and goes back to low rpm and its not a DBW car. i unhooked power and i still have same problem... plz help...
