So you have either a bad generator or a broken/disconnected wire. First check the generator: [All the markings are stamped into the generator body.] 1) With the engine off, disconnect the DF wire from the generator; loop that free wire away from harm so it cannot short to anything. 2) Connect the voltmeter from ground to the D+ terminal on the generator. 3) Start the engine. The voltmeter should read something small. 4) With a piece of wire or any piece of metal, short the generator DF terminal to ground while watching the voltmeter. The voltage should go up. If you rev the engine briefly while shorting the DF terminal you should see the voltage go up to 14V or more. If it does not do this, there is a problem with the generator itself. 5) If there is a problem with the generator itself, the first place to look is at the brushes. There are 2, and one is visible from above, the other can be felt below. If either is worn short enough that it no longer sticks above the rectangular sleeve that guides it, then it is worn out and can no longer reach the commutator. You can usually make worn out brushes work briefly as a test by pushing them both down into the generator with your fingers while doing this test. 6A) If you are careful you can replace brushes with the generator in the car. Using two screwdrivers, one to remove the screw that secures the brush pigtail and one as a lever to support the bracket that the screw goes into so it does not bend, remove and don't drop the screw, pull the spring aside and pull the brush out. Drop the new brush in and connect it. The screw should be pretty tight, and the pigtail must be routed so it doesnt short out against anything. The second brush can be done the same way by removing all the wires from he generator, loosening the strap, and rotating the generator body in its cradle until the lower brush is acccessible. 6B) If the problem is in the generator, but the brushes are fine, then the chances are that you will need to take it to someone more knowledgable to get it fixed. Of course I can do it, but there is bound to be someone close to you. Or you can just exchange it for a BOSCH rebuilt. 7) When you are finished, rotate the generator back and reconnect the leads. The generator MUST be rotated so that the DOT on the strap is aligned with the DASH on the generator body. This aligns the cooling hole on the underside so the generator gets adequate cooling. Let us know what you find.
