Volvo tach shows reading when engine is off
My tack now jumps to 2500 RPM when I turn the ignition on without the
engine running. I checked the grounds and the wiring, all looks OK. How do I tell if the tach is bad or is it in the wiring? The input to the tach (gray) wire seems to have about 1.2 v on it when I turn the eignition on. Whne the engine starts the tach maxs out. Anyone know any tests I can make to narrow the problem done?
