The meters at two local parts shops show a bad diode in my alternator. Sigh. Occasional trifectas, as well as just the 'no AWD' light kicking on. I have the Bosch compact -599 120 amp alt in it, so I'm leaning toward getting a Bosch reman unit from autohausaz at $199 [after core return] unless you guys convince me otherwise. I will do it myself [I'll get the 32mm fan tool off ebay] when I also pull the transfer case gear and this time replace it [I have the part; maybe 10k miles ago, just turned it] since I also get the tell-tale 'click' occasionally. Frustrating, especially since the alt. was replaced less than 30k miles ago when I bought the vehicle. That said, it is a 9 y/o vehicle .....
