[Vwdiesel] 89 Jetta na charging system

[Dave Cook]

Travis' description sounds a bit like the Banana Rabbit.

Occasionally the alternator light blinks slightly-never fully on and only visible when driving at night.  It is enough to cause a pulsating static on AM radio as well.  

But the battery continues to get charged.  

I'm guessing a broken/loose connection in one of the two wires that goes from the alternator to the battery.
