Wiper motor wires

Recommended Posts

I removed the windshield wiper motor and linkage from my '71 so that I could refinish the well area below the windshield.

 

Here is what I found at the connections on the underside of the motor:

The two wires with the lighter colored heat insulation appear to have broken off where they were soldered onto the terminals.

 

What is the function of those two wires.  I think the wipers were working fine before I started the restoration two years ago, but I'm not sure.

 

I'm guessing I should just solder those two back on to their respective terminals but I don't want to fry anything.

 

Regards, Maurice.

The Haynes shop manual has detailed wiring diagrams that helped me with similar wiring questions. I had the pages blownup at a printers so that I could read them without a magnifying glass. The German color codes were easy to decode and it was a great help.

I'm referring to the two wires (out of three) that are covered with some sort of heat insulating material, not the brown, green, yellow and black wires, which are still connected.

 

If you click on the photo to blow it up, you will see the two wires that are broken off.

Excellent pics, and nice repair!

 

I still don't know what those particular wires do, but I guess I'll resolder them on and see what happens.

 

BTW, what kind of a finish is that on your wiper linkage?  It looks really good.

 

Regards, Maurice.

Eastwood AlumaBlast spray paint on the metal wiper frame and motor housing.  The new linkage rods are pretty bright as made by BMW.

From Wikipedia page on DIN wiring terminal numbers:

Window wiper/washer

53 wiper motor + in

53a limit stop +

53b limit stop field

53c washer pump

53e stop field

53i wiper motor with permanent magnet, third brush for high speed

Battery

15 battery+ through ignition switch

30 from battery+ direct

30a from 2nd battery and 12/24 V relay

31 return to battery- or direct to ground

31a return to battery- 12/24 V relay

31b return to battery- or ground through switch

31c return to battery- 12/24 V relay

See if this diagram makes more sense

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
