Strange electronic box

grainboy · Nov 2, 2010

Below the washer fluid bag on my 66 coupe, inner fender left side, there is a finned aluminum box, about 3x3x6 or so, with a tape of maybe six wires coming out of it. Connection ends are flat metal tabs, and plastic nuts with metal inserts to hand tighten onto a threaded lug. nothing is connected, but the box looks as old as the rest of the car. any thoughts?

It's the voltage regulator.

Sounds like an old electronic ignition control box. Got a picture of it?

Ill try to take a pic tonight. It was painted black at one point, but a lot of the paint has flaked off, especially where the cooling fins are. BTW, it is not on the front panel, but at the bottom of the inner left fender. I know where the voltage regulator is.

I agree with Pete. It sounds like it's an electronic ignition box. A PO might have put electronic ignition in at some point and then decided to change it back without bothering to take the box out.

When I got my car, the PO had one of those from a granda installed. (he had it bolted to the inner finder as well) Talk about a rat's nest of wires! One of the first things I did was to get rid of it and go back to old school breaker points.

If it isnt connected to anything, just yank it out.

i also agree that it is an old electronic ignition box. perhaps an early generation mallory or MSD box.
