I have a 2002 SP2 that I am having a hard time tracking down a current issue.
The issue: I was riding in town and suddenly I lost all lights and gauges and I coasted to a stop.
I towed the bike home and found my less than 1 year old Shorai battery was completely dead. I hooked up a battery from another bike and my gauges and lights came on but my PC3 did not light and my fuel pump didn't prime. I then took the PC3 out of the system and connected my ECM back in and still no pump priming.
All fuses are good
I verified continuity through kill switch
Verified power passing through the bank angle sensor relay
In checking the fuel cutoff relay, I am finding no voltage at the brown wire w/black stringer. Looking at the wiring diagram this comes from my ECM. I then tried a ECM off a buddies SP1 and still no voltage at that wire.
In undressing the bike I have found some crispy connections at the rectifier. The 3 yellow wires coming from the stator read 0.5 ohms respectfully and none are reading continuity to ground. I'm starting to think my charging system took my battery out but what else could be preventing the pump to prime?
Thanks in advance for any helpful input I receive
