M20 starter wiring


Guest Anonymous

I'm starting the electrical stuff on my M20. Before I do anything I want to test to make sure the starter can crank the engine, and then go from there. The battery is out of the car, so I will use jumper cablesto just test it. Here is the plan:

Put black jumper cable on engine metal somewhere. The engine is grounded to the car.

Put the red jumper cable to the starter terminal with the big red wire coming off. Is this right?

The starter motor has a little spade connector coming off of it. Do I put that to 12v to crank the engine? Or is the starter signal one of the other screw posts? (there are a total of 3, I think). I haven't been able to find a wiring schematic anywhere.

Thanks all.

I tried it...

I can hear the starter spin up, but it does not engage the flywheel. This means the solenoid isn't engaging, right?

Here's what I did:

Jumper cables from battery sitting on ground. The black jumper cable went to a piece of metal sticking off the intake manifold, and the red wire went to the terminal with the big red wire on the starter motor. I connected the green 2002 voltage regulator wire to +12 and the e30 black/yellow starter wire to the 2002 starter wire. Then I turned the ignition switch.

Is there a separate wire for the solenoid?

Many thanks yet again.

Check the solenoid, it should have two prongs. One on which you have already connected a terminal, and the other where the terminal SHOULD be connected...

    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
