Test No. 9: Tachometer Does Not Operate
Disconnect instrument panel connector "A". Start engine. Using DVOM set to Hz (Hertz), check voltage between connector "A" terminal No. 9 (Light Green wire) and No. 10 (Blue/Black wire). See Figure. If voltage fluctuates, replace circuit plate. If voltage does not fluctuate, repair Light Green wire between connector "A" terminal No. 9 and igniter (SC300) or ECU (SC400).
