Tachometer in 1978 930 not working anymore
Hi
I have a 1978 930 were the tachometer suddenly stopped working.
Boost gauge still working, but tachometer shows 0 all the time.
I am not sure were the wire for the tachometer goes, so if anyone have a wire diagram it would be good
I guess I have to check the tachometer it self, and also the wire/signal.
Is the signal going thru the ignition box? I have now a MSD ignition, and have seen that people having trouble with signal after installation, but this box has been in the car for 2 years now.
I would be very thankful if someone could give me some tip to fix this
Have also read something about a bad alternator could give this fault?
Only problem i can se so fare is the tachometer. Everything else works perfect.
Sorry for the bad english, but hopefully you will understand what i mean
Best Regards
Tor Erik
