When I turn the ignition key to on, the tachometer will cycle from 0 to max rpm and back about 10 times a minute whether the engine is running or not. Also the oil pressure gage is pegged high. Just wondering if this is as simple as a missing wire. The tach is run off the alternator and the engine is a Volvo-Penta diesel with a Volvo-Penta insturment panel.
Thanks for any insight.
