Electrical issues...

Hey Guys... so 7 years ago I dismantled my car for a quick rebuild... everything worked then! lol!!! while I have a few other things like blower motor etc, most I can figure out but two I think I'm on right track but trouble shooting electric is not a strong point...

 

1.) Turn signals`... All lights are new and just installed LED in rear. left side turn signal works perfectly but the right not so much. Flasher is new and 3 wire change out. When I turn flashers on everything works as it should but in blinker / turn signal mode nope! Went to fuse box. flashes on right nothing on left. Little doohickey in column is set to tolerance as per book. I have purchased a broken one to see if I could use it to understand it and maybe re-whatever it to work without success. I'm leaning to column turn signal stalk... thoughts...

 

2.) Parking lights... get power to left side no power to right.... put a test light on switch in dash ... it looks like both the left and right are opposite each other, ( I have not physically taken out switch yet just gauge cluster ) I would think they would be on same terminal...

 

I have tried to explain as best I can... Looking for a jar of 2 cent pieces thrown in here!

Pull the turn signal switch and use a Multi-meter to check the continuity between Pin "54" and "R" when the stalk is in the right turn position.  If no continuity between the pins, you have a bad or dirty turn signal switch.  You could try cleaning it, but that doesn't always work.

Is your '72 a European model or was it delivered to England as a US spec car?

6 or 12 fuse?

Here's the schematic for a 12-fuse USA "roundie" (round taillights).

The right and left side turn signals and flashers are on two different fuses (#5 for Left, #6 for Right). 

Are your turn signal lamps all LED? If so, they need a special flasher unit to work like the incandescent flasher.

Hope this helps locate the problem.

Hey John   Thanks!  that schematic is so clear and legible  Delivered as US spec and 12 fuse model. The LED I was referring to are the tail light upgrade from: classicautoleds.com/led-lights/bmw-2002/bmw-2002-1966-1973-led-light-set\ 

Nice and bright! Easy upgrade and install and just have to figure out whats wrong! Had problem before I swapped these in and was hoping might fix problem at same time! This is the part that includes the wiper function into the right side directional btw.

Shows part number 1 352 958 on housing.

 

Parking light seems to be switch. Will play with it tomorrow!

    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
