2002Scoob, Happy birthday! Good luck getting your car started. TobyB and ray_ true and funny. My guess is we’re a few years older, chuckle. Alex

 

 

I think he knows the pros and cons of hitchhiking.

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

I’m not about to read all of this, but make sure your tach wire isn’t grounding out, which kills your spark.  Just pull the tach wire from dizzy or coil and see if it’ll fire.

And yeah, I assumed you tried running a Hotwire straight to coil from positive battery post, but a few recent comments say no.  With a Hotwire to a good coil, a jumper cable from negative battery post to block, tach wire disconnected, some starter fluid in air filter, something better fire, and if it doesn’t you try a different coil or dizzy setup.

Man,

 

Still slacking. Had a rather exhaustive weekend down in Italy (holy hell Roger Waters puts on an epic show!!) and have been decompressing/putting allot of time in on the bike after work to burn off all that amazing food and gelato, haha. 

 

I wanted to tackle it this weekend, but looks like I'm back down to Italy to attend a bike festival at Lake Garda, so additional trouble-shooting will have to wait till next week. 

 

I'm going to start looking into a new work-shop space soon, Germans are a bit up-tight when it comes to having hobbies in public spaces/garages, let alone the fact the lights are on a 5 minute timer in my building's parking garage... makes things a wee-bit frustrating to work on stuff. 

 

but yes! I will get this solved next week.

The sympathy over here is drying up, you know, Scoob....

Yah.... I know. It'll be figured out soon. :)

 

I'm excited to drive the car, but at the same time I've got this weird internal struggle that I wanna stop driving/building/working on petrol powered things. Deep Petrol-Head background with a conflicted eco-conscious mindset. That combined with a lack of workshop, and focus on other distractions lately means Brunhilde has taken a bit of a back-seat in life. . 

 

That said... I'm officially putting away pennies for an E-conversion... The motor I build last fall that's in the car is going to either get sold to fund it, or become a garage (or bachelor living room?) museum piece. (the #matching block is in oiled, dry storage.)

DING DING DING DING!

We’ve got a winner!

 

I’m gunna need your address because a Snickers will be headed your way!

 

How it went down today-

 

I went ahead and refreshed the body ground on the car, a few of the wires were a little fatigued, so everything got cut back with new ring terminals.

I then also ran a ground wire directly to the body of the distributor so there was no question. I did not, however, run a direct positive to the battery, as I wanted to check one thing at a time.

Again.... no spark.

 

So I checked the app and even though there’s 12.5 volts going into the dizzy, the 123 app’s voltmeter read low...

 

So here’s the thing... I’ve always had a second black wire running to the coil, but never knew what it was for.

 

I guess yah, it should be for a Tach... but my car doesn’t have a tach. So with the app open and the ignition on, I flicked off that extra wire which let off a sharp blue spark when it disconnected, and the volt-meter on the app jumped to 12.5 volts.

A few cranks later and it was off to the races!

 

But now this just leaves me questioning exactly what that black wire is for, and if it is indeed for a tach, what changed over the winter that it went from not grounded to grounded or whatever the issue is.... like I said... it’s always been connected to the coil.

 

I’m obviously going to leave it disconnected, but I’d sure be curious about what went wrong and why... the last thing I want is an electrical fire.

Part of me thinks back to the other only thing that went wrong over winter- My hazard light button failing.

 

I haven't dugg into fixing that yet (other than a business card wedged in there to keep it off) but I can't fathom it being the issue even if a lot of electrical goes through that connection.

    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
