That's a good idea for mounting the resistors, might as well use the heat they produce. My tail lights are all LED, just the signals in the housing are incandescent. I can live with that. I just took it out for it's first drive after the 12v conversion and I noticed two things. My gas gauge is on empty (not related to pump prices ;)) Did I get the runtz in incorrectly? Also, my Ammeter never actually goes to the charge side, even on the highway. Is this something I need to adjust in the voltage regulator?
