I haven't put this back together yet. Been driving the Silverado.
Minivan has been down for 2 weeks. Battery light came on and I thought it was the alternator (got it warranted at O'Reillys) but turned out to be these battery cable savers I installed a few months ago. I installed those because the original power cable are too damn short. Seemed like a great idea...actually found another thread on the Chrysler minivan forums with someone having the same exact problem with those battery cable savers!
After i reinstalled the alternator, I monitored the voltage it it kept dropping to around 12V. Then I noticed those battery positive cable savers were smoking! I checked the voltage at the alternator stud and I had a full 1.0 voltage drop!
I wound up replacing the alternator wire, which goes down to the starter with a fusible link. Removed it from the engine harness wiring. Used 2 guage wire for alternator and also a new 2 guage wire to the stater. The third positive wire was for the ECU. That one I spliced with the original alternator wire I took out. I bought the Harbor Freight hydraulic heavy guage crimper for that.
Put everything back together and voltage was 14V at idle. I checked the voltage drop from alternator to battery was now in millivolts! Seemed like way overkill, lol. It just looks a little gettho, but who cares. I gave it back to my wife..."sent it!"
FIXED!
