I have two gauges that I absolutely want to get working.
1986 Fiero 4-speed Stewart Warner gauges (after market)
I need to find out how to test the sender at the 3-prong connector in the engine bay. I am getting 4.3 ohms between the ground and most outer wire on the tank side. I am getting a reading on the gauge side when I jump the ground and signal wire, testing at the firewall connector (in the engine bay). Someone, please tell me how to test at the connector in the engine bay and testing at the fuel gauge when connected. the fuel gauge pegs out empty.
I need instruction on how to test the oil pressure gauge while it is installed in the dash. Currently, it pegs out when I turn the key to the On position.
