69 T Alternator Wiring Question
 

I removed my alternator last night the have it tested due to a no charging condition. When I removed it there was a capacitor with the base bolted to the alternator frame and the other lead bolted to the + terminal, same as the battery lead. On the capacitor are the following markings:

Beru
FK 216/13
2.2 uf 110V=
Max 100 C
Germany
KZ

1. Is this just a noise filter? Is it required to be there?
2. If the capacitor is required, is it suppose to connect to the same lead as the main battery lead?
3. In addition to the large lead going to the + (bat) connection on the alternator there is another connection (~12 gauge wire) that is connected to a terminal near to the pigtail connection that goes into the regulator. (I hope to be able to post a picture later.) I verified that the wire goes to the regulator but I want to make sure it is wired correctly to the alternator. I cannot find any pictures of the back of the alternator to verify the wiring is correct. Does anyone have a picture of how the wiring should be?

I dropped off the alternator at a local shop. They are going to test it and let me know if it is good. If it is good, I need to make sure the wiring is correct. However, I have a feeling that it is bad. The battery has 12.2 volts with nothing running or on and when the car is running I am getting 11.5-12.1 volts and less if I turn on headlights.


Thanks

This is a noise filter.
Capacitors of various sizes have been used on generators and altenators on many vehicles to cut down on the spikes created by the unit.
If the cap is removed you may or may not hear a "whirring" noise in the radio (usually on AM).
It does not damage anything not to have one....but as long as it's there..put it back on.
If you already have that noise in the radio...even with the cap in...perhaps you need a new cap.
