Hey guys, 

 

So, I have an issue and need some new direction on how to fix my issue. please, and thank you in advance.

 

When I turn the key, I receive very little power, and sometimes no power, to ANYTHING in the entire car. when the key reaches the "farht" position, nothing happens.

 

The battery is ruled out. 

I am recieving 12.4 amps from the battery. and 13.5 from the alternator when running. 

 

The reason I believe it is the ignition switch is: When I jump start it, It will run like a top. (Except the other day it died on low rpms but thats for another topic) 

 

I have checked all the wires and everything seems to be in order. It must be the ignition switch.

 

My question is... do I need to get a whole new ignition assembly, or is there something within the switch that I could check out?

 

thanks, 

Jeremy

If you look on the back side of your ignition switch, you'll see that the electrical portion (brown bakelite) is a separate and replaceable part from the mechanical (key lock) portion.  Disconnect the battery and mark all the wires back there to make sure you replace 'em on the proper terminal.  Then remove the electrical switch.  You can try cleaning it with electrical contact cleaner, but you probably need a new one. 

 

Installation is easy, so long as you marked the wires!  I'm sure Blunt has the switches.

depending how you are jumping to get a start, cheap insurance is to buy a new ground strap body/block type 

 

 

This. I'd look very closely at battery cables ans connections before replacing the switch.

Stop reading this! Don't you have anything better to do?? :P
Two running things. Two broken things.

As above, clean, replace, tighten all of your battery cables and fittings.  Battery post fittings may look good, but can have crap inbetween.  When you jump, you bypass the battery post crap.  Some cheap cables can have corrosion inside the covering.  The ground strap from your battery box to the engine might also be frayed or rotten.  Clean and tighten cables to/from starter to battery and also to the engine block.

 

If it is your ignition switch, you can usually tell by looking at the connectors.  You'll see that they are burnt from shorting.  If the connections are clean it's likely your switch is ok.

    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
