Oil Pressure Light

Post by wmasscaddy »

My oil pressure control relay that plugged into the fuse panel died a wet, rusty death long ago. I have an oil pressure gauge, but I don't look at it as often as I probably should. But there's an idiot light already in the dash. If I jumper (in the relay panel) the idiot light to the sender that switches 'on' when oil pressure drops, would that work? Would it light up if the oil pressure dropped?

> I don't need the dynamic thing, I think the light might always be on at idle when warm?
> Would it be better to put the sender at the head or the filter?
> Does the light already have 12v, and just needs a ground to light up? Wiring diagram looks that way to me.
> Some PO destroyed the buzzer. Good job, PO.
> If I could just plug in a new Oldruck Kontrolgerat that would be fine too. Haven't found one.

I'm pretty sure the oil light has positive on one side and when the switch gets grounded it lights up.
I'm not sure which plugs you would jumper to bypass the relay.
Bound to be one coming from the switch and one going to the buzzer.
