Rear Strut Brace is in, battery in, now I have a problem


Recommended Posts

The red charging light is staying on when the key is out of the ignition. Bad ground? Voltage regulator? Something else?

Red light goes out when the key is turned to the next detent.

What can it be?



BTW, I bought the brace from Matt Kehler from Manitoba.....fits great..and I stripped it down and repainted it with low-gloss black....Thanks again Matt.

I suspect a bad diode in the alternator...coincidental? Not sure. Double check all wiring, then test alternator.

or happy to help.

Alternator light on with the ignition off indicates that you are back feeding the alternator from the battery.

Did you run your positive to a junction box or straight to the starter?

How did you connect the rest of the positive connectors that terminated at the battery?

Make sure no wire is frayed, all the connections are clean and secure including the ground wire from the back of the alternator to the front cover.

I would also run a negative ground from the block (where the original negative was) to the driver side inner fender.

Let us know how it turns out.

Monster Mike,

Please email me at: cram775@gmail.com

I need to get one of those braces for my car. I just cut out my battery box in front and that brace looks super good, especially since one does not have to drill into the strut tower.

Otherwise, can you post Matt's contact information, that would be cool. I think you mentioned Manitoba. I know that Canada, but no worries, I'll order one from his even if he is North of the border.

Thank you!

My money is on a bad ground. I'd take off that dinky screw, and run a bolt from behind the panel where you've put your ground.

Scrape the paint on both sides, and use a star washer to really bite into the metal (also on both sides)

    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
