Troubleshooting Gauges- 68
I have an aftermarket autometer gauge cluster installed in my 68 and ever since I have had my engine rebuilt I haven't been able to get readings on the oil pressure or water temp gauges (the tach and voltmeter work great). I assume that since the needle sets to zero, once the engine is running, I have a good feed and ground and the sensor feed is my problem.
Any idea what type of range I should get if I hook an ohm meter up to the sensor lines for oil and water? Is there something else I am missing?
