Warning light problem.
I’m having a problem with the idiot lights on my 84 928. When I start the engine when it's cold, everything is normal but if I turn off the ignition, and restart it, all of the warning lights come on and remain on. Stop lamp, washer fluid, coolant level, brake fluid, brake pad, parking brake, engine oil (gage normal), high temp (gage normal), low fuel (gage normal), low oil (level normal) along with the “!”. They don’t flicker or flash but remain on steady until I turn the ignition off. I’ve tried cleaning all ground points I can find but it doesn’t act like an open ground. It acts more like a switch is holding everything out. Does anyone have any suggestions? I would appreciate the help.
