I have two circuits. One is a High Water Temperature circuit to turn on a light/LED at a desired temp, and the other is a Low Fuel level circuit to turn on a light/LED to indicate low fuel.
When I turn the Ignition to start, I want the lights to both come on as a test. Problem is that if I tie these lights up to the (start) circuit, they will both come on, but if i have a fault (high water temp or low fuel) they will both come on. Would placement of a Zener diode on one of the light leads (before it is stripped into the start circuit) resolve my problem?
