battery not charging
My alternator in my 83 CJ7, 258 engine, is not charging the battery, this
has been an intermittent problem the past few months. I have now used 2
different alternators, and had both of them bench tested. Also I have a new
battery (6 months old Optima), and new battery cables. Fan belt is adjusted
properly and spinning the alternator.
My next guess is that whatever wires meter the battery voltage and tell the
alternator when to turn, or however that system works needs to be cleaned or
replaced. Can someone explain to me how this charging system works?
As I see it there are 4 connections to make this work.
Ground - The alternator grounds it self through the engine
Positive - the post coming out of the back of the alternator, connects to
junction mounted on fender
Side A of plug - Also a positive wire ( also a red wire) that connects to
the positive post as well, then continues to fender
Side B of plug - This is a thin gauge wire, black in color, that ties into
the wiring harness, and probably up through the firewall of the jeep. What
does this wire do? where does it connect to?
Any ideas?

Re: battery not charging
That thin wire should be the "sense" wire that tells the voltage regulator
at what rate to charge the battery. It normally comes from the instrument
cluster, usually from one side of the the Alternator light, and then feeds
the regulator with the voltage from which the regulator determines when to
turn the alternator onto its charge mode.

Re: battery not charging
Are you saying that the one I have called "Side B" feeds into the ignition
switch?
