Hi Everyone,
I'm building a 1937 Plymouth and getting ready to start wiring the dash.
It will have gauges but I also want to use idiot lights.
I know how to wire the voltmeter light so it comes on when you turn the key on and will go out when the car is started, but how do I wire the Oil and Temperature light to do the same?
In case this is not clear i'll explain it this way. I have a 2000 dodge.
When I turn the key to the run position all the idiot lights on the dash come on.This is the test mode.It shows that the bulbs in these lights are working. When I start the car those lights go out. I want to do the same thing with my 1937 Plymouth.
Thank You, Barry

Your 2000 Dodge has a computer that tests all the lights then reverts to operation mode. Your 37 Plymouth does not have that unless your using a wiring harness and computer from a later vehicle. You could come up with a circuit using relays to facilitate a test scenario, but it would be rather complicated.
