I cleaned up my alternator. Removed the voltage regulator, put ox guard on the copper to aluminum junctions, polished all the corrosion off surfaces and brushed the corrosion off the voltage regulator heat sinks. The alternator wire is still suspect and likely getting replaced tonight as it's original and there is enough corrosion at the battery end and I just don't like the factory ends. Much less in the way of lights dimming if you cruise and roll a couple windows down.
The jetta melted a fuse for the fan module a while ago, and now that you guys mention that I am going to pull that aprt tonight and go to town on it.
This is temporary, once the car gets an optima it is going in the trunk.
