An after thought to those people I sent the LED list. There are two things not mentioned in the email. 1.0 My car has a DMC-1 gas gauge corrector. It takes its power supply from the warning light on the dash. Apparently the requirement is about the amount of current that LED draws, as the Warning LED is always on, whether or not you're about to be walking. Three solutions: 1.1 Leave the incandescent in there. It will always be on a very slight amount (not visible) and light up on a low tank. 1.2 Figure out how to power the gauge corrector differently 1.3 Live with the Warning light on all of the time. 2.0 Alternator light. John Hervey and I have had many discussions about this one. The alternator may or may not be self starting (not a lot of residual magnetism in the assembly. My car, with the factory Motorola alternator seems to start alright with a LED indicator. No other problems. John says that his replacement, high current alternators need the incandescent to work correctly. I doubt that, but can only argue theoretically, as I don't have a car with one of his bigger Berthas installed. Here's the theory: the alternator uses rectified current to power the regulator and field, once it has started to generate power. The warning light acts as the current source to get the alternator started. Remember the Chrysler ads from the late '50's or early 60's with someone starting the car and removing the battery (after the alternator gets going) and driving from Detroit to some other destination? Guess I've dated myself. Well anyway, the Alt warning light only goes on when the alternator isn't (before the engine starts, but the "ignition circuit" is powered or when the alternator fails and becomes a load for the lamp as its supplying all of the current to the regulator that it can. Oh, BTW why are there two sets of diodes in an alternator, six big ones for the full wave bridge to rectify the alternator's output and a three puny ones for a half-wave rectifier to supply the regulator.
