Tech Help?

[lyndondb]

I have two questions:

1 - 1969 b body, 3 -speed wiper motor - what color is the barrel on the motor. Appears to be some kind of copper zinc?
2 - Same car when the switch is turned on the parking lights and interior dash lights come on.
I am told it is "hunting a ground". I have checked the light grounds on the radiator shroud, new engine to firewall. What am I missing?

Thanks in advance.

Not positive on the color, but if it is a "copper-zinc" color it was probably coated with a zinc chromate coating (very toxic & no longer used). You can probably mimic it with anodizing (really close) or get in the ballpark with some custom-matched spray paint.

For the lights coming on..... I'd look for a wire crossed/shorted somewhere. I can't remember exactly how the 3-speed wiper motor works, but it has one wire for each speed coming through the bulkhead disconnect (top plug if I recall correctly) so there's several wires that could get crossed/melted into another wire. Does ANY speed turn the interior lights on?

Wipers really have nothing to do with it. When the ignition switch is turned on the parking lights come on.
Thanks for the information.

Beekeeper has a good thread on this with duplicating the color with paint. My guess would be yellow zinc or cadmium.

I did mine in yellow zinc and they turned out perfect.

I agree they do look good. Does the barrel come off by taking out the large screw in the middle?

The parking lights and dash lights should come on at the same time when you move the switch.

Make sure that the brass grounding strap in actually grounded, and not sitting on a pile of paint build-up on the stud it affixes to. That would cause a 'grounding hunt' as you put it, and the easiest path would then be through another switched item on the instrument panel.

The grounding strap is new and going from the firewall, (which i sanded to bright metal) to a chrome bolt and washer to the intake.
Thanks for the info. I will use it the next chance I get to trouble shoot.
