Electrical questions for Ms. FrankenVicky
Working out some electrical issues, for which I could not yet find answers. The car came to me thusly:
cover removed from the cut-out; the relay seemingly did not work; the headlight and horn wires were removed from the cut-out and taped off; the tail-light did not work; the ammeter was pegged at zero; only the dome light workedI have replaced the cut-out with a solid-state unit, having hooked up the headlight and horn wires, both now work, but the ammeter only shows a drain when lights are on or horn is sounded. It does not budge to the right of "zero." My questions are as follows: 1. If the ammeter shows a drain but not a charge, do I suspect the ammeter or the generator?Thanks in advance, and sorry for all of the questions at once. |

Loosen the fan belt so the generator spins freely. Take a hot lead from the battery cable/starter and touch it to the front of the cutout. The generator should rotate (motor) if it is functioning. Also check the setting of the third brush.
Normally cars with cowl lamps would not have the parking light socket in the headlight. |

Re: Electrical questions for Ms. FrankenVicky
Have you removed the wiring/bail at the end of steering box to see if wiring is ok and also put together the right way? I have two bulb plus cowl lights. the light switch is one click right is low beam 5pm,two clicks high beam 4o'clock position six oclock is off and to the left one click should be cowl lights.

Seems like most of the major parts shops only sell two versions of the wiring harness - one bulb (with cowl lights) or two bulb (without cowl lights). Last edited by Lefty W.; 06-19-2011 at 10:53 PM. Reason: Added last sentence |

Re: Electrical questions for Ms. FrankenVicky
Horn sounding while turning the steering wheel means there is a short at the bottom end of the horn rod. On the black plastic base plate of the headlight wiring harness in the center is the stand up spring contact for the horn rod. This is passes through the brass rotating switch plate that makes contact on the black plastic plate and presses against the end of the horn rod. This stand off spring is touching the hole in the brass rotating plate and grounding the horn. I place a piece of shrink tubing around the length of the spring contact, leaving the end uncovered, so it will not contact the brass rotating plate. On some of the repro switches the hole in the brass rotating plate is smaller.
