I had an occasional no start issue where the car would crank but not start, found there was no V+ at the coil and found the solder joints on the OBC relay were in bad shape.
Took it apart, cleaned all contacts and resoldered the joints.
That definitely fixed the starting issue and the car starts now every time without any issues.
However, now my Tach and OBC died (obc lights are on but won't display anything) tach stays at 0.
I am running MS, tach won't move even when simulating pwm out on the tach pin.
I checked fuses and none of them were blown, however fuse 21 was 30amps so I went ahead and replaced all fuses with the correct value. I'm afraid that maybe too much current went into the cluster and burned a trace?
Any idea what could be the culprit?
thanks!
