Hey folks,
re: 2003 GTX DI 150 hours -

Made the mistake of jump starting battery when it was still installed. Actually ran for an hour, then second time no dice.

Now no beep or start even with new battery. Diagnostic showed that "relay has no power signal from middle modualar box. All fuses are fine.


I have read that since it is a 2 stroke 2003 its the MPEM (computer) may be needed from the jump start shock. How does one repair a big MPEM like this one? It has 4 ports plus the fuse box on it. Looking for the exact spot for the diode to replace inside it.
