Last week I ordered a replacement alternator from DMC Houston. The Ducy I had was overcharging the battery and I had to replace battery as well... The model of alternator I got from Houston is a Delco.... Warren sent me a copy of the Service Bulletin for replacing the alternator.... I also checked the archive messages here as well.... I didn't want to cut all the wiring back to the wiring harness plug, so I capped off the brown wire down by the alternator and connected/spliced the new single wire plug that came with the new alternator to the yellow/brown wire. So, I have 2 questions. 1. Is this the correct procedure from going from a 2 wire connect to the 1 wire connection??? and 2. If this is, why is it that now my idle constantly cycles from 750 to 1200, the engine is rough and now my fans don't kick on until 240 degrees? I have the fanzilla installed and have never had any problems with it. None of this happened until I swapped out the alternator??? Is this just a coincidence that all this happened after the swap??? Can you all point me in a direction to start looking for the problem? Thanks.
