Alt rebuild
Not all alt rebuilds are the same. Most are good with the bearings and brushes. The big difference is in the Diode block. Most Alts have diodes that rectify the current generated. A simple bench test is good most of the time but can miss an intermittent problem or irregular current.. A good alternator rebuild shop will test the unit and give you a readout of amperage vs. rpm. 50 bucks is a little pricey for the diode block on its own so I am thinking that they had to take the unit apart, install a better diode pack and then test. Definitely worth $50.00 considering all the time and aggravation it will save you.
After cleaning as many connections as you can think of. Make sure that the alt has bee given a professional going over and be sure that you have a readout of rpm vs. amps.
