Information about modifications and repairs to the Electrical System and Ignition on your BMW 2002 and Neue Klasse car. Alternators, batteries, coils, fuses... Submit an Article if you have something to share.
I'm often asked about the proper wiring for the typical Blaupunkt radio in the early BMW models and am including a diagram showing the proper locations for all electrical wiring. Earlier and later radios have a slightly different configuration. If anyone has specific questions please contact me through PM or through our website: Vintageblau.com
The wiring process for a vintage Blaupunkt radio is generally a simple procedure. Besides the antenna wire and speaker cables, the only other
Introduction:
The first step towards upgrading your points-based ignition system is to figure out which Pertronix belongs in your distributor. If the distributor has ever been replaced, you have to make sure the distributor matches the Pertronix you are ordering.

While the electrical system of the 2002 is no Lucas catastrophe, it's still 60's level technology and has its fair share of shortcomings. I'll refrain from labeling it 'poorly designed,' but the headlight circuit is one of the primary 2002 electrical systems that has lots of 'room for improvement.' Also, with the popularity of adding additional fog and/or driving lights to these cars, this makes for the perfect time to rewire and improve this whole system while adding such upgrades.
Fuse Box Wiring Color Code Cardboard Remake
I've designed new artwork for the back of the fuse box. There are a few things to note:
1) When printing, remember to set the print size to "Actual Size". Print to A4 paper.
2) If prompted for password just type: faq
3) Remember to use a suitable cardboard. I used a heat resistant, waterproof 350gsm paper.
4) Use proper safety when using X-Acto knife or other blades.

Introduction:
If your outside turn signals work, but the inside indicator doesn't (or is intermittent), the problem may be curable by a simple procedure to refresh the flasher relay itself. The problem is that the contacts that operate inside the relay itself rely on a small brass spring, which weakens with age. By carefully bending this spring back into shape, you can save the expense of a new flasher relay to fix the simple problem of the

By Chris Blumenthal
Introduction
Most 02 pilots have experienced turn signal problems. The dreaded indicator light "no-blinkie" and flash-only-once syndromes are among the most common. Another symptom is the fast-flashing indicator. Most of these problems seem to be traceable to excessive resistance in the turn signal/hazard flasher circuit. The '02 turn signal/hazard flasher circuit is
Congratulations! You have purchased a unique electronic tool specifically designed for tuning of the BMW Model 2002 - by a 2002 enthusiast! This unit is100% hand built.
To use the tool - First make sure the car is in the NEUTRAL position (and/or Park for automatic cars). No key in the ignition, all accessories off (FAN OFF).
Locate the diagnostic port under the hood (Driver’s/Left side close to firewall). Simply plug the diagnostic tool into the port; the plug is polarized so you cannot co
Troubleshooting your Cold Start Circuit
The Tii cold start circuit consists of several components. If you suspect the system doesn't work, a few basic troubleshooting steps with a voltmeter will help you track down the problem. And don’t be surprised if it isn’t always the cold start relay (CSR) - the biggest “aha moment” I had was realizing that the thermo-time switch (TTS) provided the timing, not the CSR. (Lesson learned - if the system isn’t spraying fuel long enough, check the thermo-t
The objective of this modification was to install an electric radiator fan with variable speed control. Specific design goals were as follows:
· Minimize loss of radiator frontal area
· Mount fan flush with the radiator
· Minimize axial motion of the fan assembly under driving conditions
· Implement high-frequency PWM speed control
· Control fan speed as a function of radiator outlet temperature

As many of you know, the original ceramic fuses used in our car are a bit troublesome. The small contact areas mean that they are extremely sensitive to corrosion, and although the fuses are covered by a clear shield, they are still very exposed to the elements. I had enough of turning my fuses in the sockets and scrubbing at the contacts every other month. This, in addition to restoring the connections throughout the wiring harness, will greatly improve the electrical system in your car. You wi

Here is how I installed a Crane Cams XR3000 ignition and PS91 coil in a 1976 carbed 2002. Before this installation, I had little experience with automobile ignition/timing, so I found the available guidance difficult to use.

European turn signals use only a single wire to power their lights while US turn signals use 2 wires. When you to go install your European turn signals on a US car you are faced with a dilemma. Do you use just one wire to power the European turn signal or do we modify the European turn signal to accept both wires. The answer is you modify the turn signal to use both wires!
Trying to use only one of the US wires to power the European indicators doesn't work because the flasher relay t

Marchal is a French manufacturer of high quality automobile lights founded in 1923. From its inception Marchal was very active in motorsports, especially in the 1950s through the 1980s. Marchal lights and sponsor decals can be seen on many winners of the 24 Hours of Le Mans and the Rallye Monte Carlo. There are many Marchal lights made during the 60s and 70s which are appropriate for BMW 2002s. The lights are exclusively made in France. Labels inside the housings give the exact week and y
How to build your own LED (round tail) tail lights for around $100!
Preface: There are a few things you need to know before starting this project!
1. Light output- Yes these are really bright, but no they do not look as bright as the original bulbs when compared side by side, although they are much much brighter. The reason for this is the way the light gets spread around in the tail light bezels. With the stock tail lights, they use regular bulbs and the brightness of the bulbs is directly af
1. Basic Description of 02 Charging/electrical System The 02 charging system converts mechanical energy into electrical energy when the motor is running. Your 02 requires electrical energy to (i) start the motor and run the ignition system, and (ii) operate electrical accessories (e.g., lights, wipers, heater blower, and stereo). Whenever output of the alternator exceeds the demand of the system, that output is available to recharge or maintain the battery’s state of charge. The charging syste
Cibié is a French automobile lighting manufacturer founded in 1919. It is pronounced like you are saying C-B-A. There are many Cibié models that are period correct for 1960s and 70s BMWs. In 1969 Cibié was merged with Paris-Rhône, then in 1978 merged with Ferodo and Marchal. These 4 previously competing French auto parts companies formed Valeo in 1980.

Cibié Super Oscars ( also called 200 series ) - the largest light at 8.5 inches in diameter. 5.5 inches deep.
Background:
I have known of my bouncing timing mark for sometimes and have learned one of the root causes is ignition distributor shaft axial and/or rotational play. So I called well known distributor rebuilder and told me rebuild time is approximately 5 weeks including shipping both ways. I would have sent it to him if it was Winter season here in Ohio, but to do it now means I won’t be driving my "Ultimate Driving Machine" for 5 weeks. So I decided to take on the task and repair it myself.

By Rueben Antman
Introduction
Many common signal and flasher problems can be dealt with with some simple maintenance of the electrical system itself. Often this is prodded by some little electrical quirk that one is trying to get rid of. In my case, the "B" light on my dash was not blinking when I had my turn signal on. Because I knew I had a good flasher relay,

The hazard switch circuit is probably the most complicated circuit in the 02. Here is how it works, in a nutshell:
The Relay
The flasher relay contains two solenoids/flasher circuits. One drives the turn signal and hazard flasher bulbs, and one drives the flasher indicator bulb in the instrument panel. The flasher relay has four terminals:
