How to maintain and troubleshoot the car’s electrical system

Easy removal of the Tii alternator

When removing the tii alternator from the bottom, disconnect the sway bar end links and remove the (4) hold down bolts to move the bar forward enough to allow the alternator (with pulley) to drop out of the engine compartment. Also, if you remove the (4) bolts that hold the radiator to the bulkhead – then shift it over about 1″ toward the passenger side, the long pivot bolt can be removed from the upper alternator mount (without draining the coolant!). I must admit, replacing the v-belt is tough; it is VERY tight between the fan and radiator.

We have all seen numbers on the 2002′s terminals and wire numbers on schematics and perhaps thought nothing about it. It probably comes as no surprise to learn the numbering is actually part of a German industrial standard and is used on all German cars as well as vehicles produced elsewhere.

Let’s keep this simple and point out a few basics for you to remember. Circuit/Contact 1  Lead to ignition points 15  Switched battery voltage — through ignition switch 30  Unswitched battery voltage 31  Ground return 50  Starter solenoid cranking switched voltage Ground wires are usually brown And for Bosch Ignition Coils – If the letter “W’ is stamped on the bottom of the coil, it must be used with a ballast resistor.

During the production of the original Shop Manual, BMW produced electronic copies of the original electrical diagrams.  If you have a problem and need to troubleshoot your wiring harness, these are real time savers in resolving electrical gremlins.
