Speedy Jim Question (or any other smart one)-- Idiot Lights

Yes, your scheme will work. The Gen Reg sends Pos 12V when the Gen is charging. It sends ground (Neg 12V) when not charging.

How about modifying the rearview mirror itself to accept 2 tiny LED's? There is probably less chance of the sun shining on them than in the rear window.

Also, see my web site for ideas on adding audible alarms to the lights.

Thanks Speedy....

Your audible alarm is already in the plan.

The thought was to mount the warning lights below the rear window. I noticed on one of my cars, that when something goes wrong, the rear view window is the first look out of the car. The windows are tinted so being able to see them shouldn't be a problem -- very smart observation.

Harh! And just in time for the first Snow! :) (Hey, if you are running an alternator without a 'gen' light, it's not charging. Dress warm!)

How about run your ignition system through a relay controlled by oil pressure, no pressure, no run, no need for a light.

Ok, dumb idea, too many beers.

.............Actually, that might work but you'd have to include a another bypass wire to the coil from the one that goes from the ignition switch to the starter solenoid or it wouldn't start.

Great ideas.... I'm just looking for a quick and easy way to get some lights in the car...
