Thanks for everyones advice. I tracked down the bad ground and wired up a "Hot Earth" setup. Replaced the battery cables and also ran new larger guage ground wires throughout the engine compartment. The idiot lights still come on and stay on when I first start the motor, but after I rev it up once they go off and stay off. I guess this is working now. The alternator may be getting weak in it's old age. I'll deal with that if it breaks some day.
My main question is about the current to the coil. First there is no + or - on it. Just a #1 and a number that looks like #15. #15 is hot and has a constant flow when the ignition is on. #1 is was not hot when disconnected, but when plugged in to the coil shows a pulsating current on my test light only when the car is running. Is this right? I left it alone for now.
I thought one side should always be grounded. Is there something wrong, the car runs fine like it is now.
