Alternator charge light on, key off FIXED, no headlights too


Recommended Posts

After a weekend of chasing wires I finally fixed my alt problem. Turns out, the alternator is fine. Along with my alternator problem, I also had to troubleshoot the lack of headlights. Had no power to light relays either low or high beam.

Any guesses as to what the fix was??

AK weather too cold (i.e. too much resistance in your old wiring)?

Wires terminated in the wrong place? Dash light bulb mixed up with alt. charge light?

Come on - please tell us so CD can stop using red.

After many hours and beers of wire chasing, turns out that my shitbag PO wired the ignition switch up wrong. I don't remember where he had all the wires going, but they sure weren't where they were supposed to be.

The ignition is the only point where both the alt wiring and the lighting wiring come together in one spot.

Here's the way it's supposed to be wired: (for a 74-75 anyway)

15-Both green wires

30-Both Red wires

50-Black with white terminal


P-Grey (my car doesn't have grey, but that's what's shown)

In summary, there was no power at either of the headlight relays and the Alt light was constantly on when the key was off.

So if anyone ever has this problem, check the back of your ignition switch...

RATS !! I was sure it was the alternator .

Wires in wrong places don't count.

Find Sheit-fur-brains PO and make sure he can't reproduce.

the battery side of the wiring to the alt light but not from the alternator side (remember the two positive wires feeding the alt light)...and the PO managed to get that feed wire onto the "always hot" side of the ign switch vs the "only hot when the ign is on" side.

Good catch...doncha love PO's? Especially POs with no mechanical skills?

    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
