1992 Prostar 205 Oil and Fuel Gauge
I just purchased a 1992 MC Prostar 205. The oil and fuel gauges do not work. The volt meter and engine temp gauge work fine. The previous owner said the sending units were bad. I replaced the oil sending unit, but the gauge still registers 0 psi. The oil level is fine. I have not tested the oil pump yet. I hear a faint audible squeal when the engine is running. Itís coming from a circuit board behind the dash.
Is the noise a low oil level warning or something else?
What are the other causes for the gauge to read 0 psi?
How would I check to see if the gauges are bad?
Is there a common ground that the oil and fuel gauges use and maybe corroded?
Thanks for helping.
