Re: Wiper Motor Wire

[i]Any[/i] motor that is supplied with under-sized wire (which would result in a high-resistance circuit) will suffer a voltage drop. The consequence will be that the motor load (imagine a wiper stuck in ice) will try to make up the voltage shortfall by trying to draw more current (power is the product of voltage and current; the motor understands that) which can result in too much current flow in the windings, which results in overheating and burnout, and maybe a short in wire in the windshield frame. Given the price of our wiper motors, suggest you go with heavier wire no matter what the color of the stuff. Austin

The wire to the wiper on my TC is original, and is grey in color, FWIW. However, if the correct gauge wire today is available only in black, why not install that and paint the darn stuff where it shows? I assume that grey paint is still available.

I think Carl's got it right, but I'd simply add that 1) we know that Abingdon's electricals were a bit short in a variety of areas, and 2) their engineers couldn't anticipate $450 for a replacement wiper motor, so, 3) why not stuff as thick a wire into the windshield as we can to keep the motor happy. Also, stay away from solid copper (use stranded, designed for flex), and consider feeding from [i]both[/i] sides of the winshield for extra current capacity if inner clearance is a problem. Austin

I recently purchased a wiper motor wire for my TC. What I received was a length of wire (grey rubber sheathed). Inside this cable this cable I found two tiny wire and a stranded coaxil type centre section. The two tiny wire surely are not expected to carry the load of a wiper motor under load are they? Please advise. [Non-text portions of this message have been removed]

According to Moss the loose strands should be twisted to form one wire and attached to a motor terminal. The two insulated wires should be combined to form one wire and attached to the other motor terminal. Personally, I don't believe they can handle the load and would replace with a heavier gauge, two conductor cable. The same OD diameter and gray color can be obtained from most elec shops.

You can also combine them all in to one wire and then run another wire from windshield wiper mount post to the second connection. Be certain that underneath the instrument panel that you run an extra wire to earth. Externally it appears normal but you end up with a much larger wire to carry the current.

BAH! Battery cable works a charm. AND you don't have to worry about putting it into the w/s frame. It won't fit! But it carries enough electrons to weld with if you have a mind... Drinking whisky helps the install process, though. Non illigitimi carborundum est, Ray According motor terminal.

I have some wire which I bought from Doug Pelton , which has ground or copper shield, a red and yellow conductors I know A4 is the terminal on the RF unit , what do I use ? What with the rest of them ? Bruce Doran-Veevers 613-299-7523
