A: Sounds to me like a bad ground wire between the block and frame. Regulator needs a good ground connection to the battery to function properly. While running, take a jumper cable from the battery - and touch the voltage regulator casing and see if the lights get brighter.

We changed the alternator, voltage regulator, high-low floor switch, headlight switch. The car is fine as long as you keep the headlights off. The wiring to the headlights seems fine also. Anywhere else we can look? Confused.......
