I recently installed 3 autozone rebuilt alternators and 1 new alternator after a 5 year stint of no charging system issues. All of these have been within the past 3 months and to begin with, I was under the impression it may just be bum rebuilds. Twice in the past couple of weeks I've gone on the road for the weekend where everything looked fine until Monday morning and then, no charge (as per my gauge and verified by a voltmeter). Battery started and ran the vehicle okay (bat is one year old) but no charging system. This vehicle is a
97 GMC suburban k1500, BTW.This past Sunday morning, I experienced the same thing and shut the car off. This time, I decided to remove the negative cable for about
5 minutes and reconnected. Voila, the charging system worked. It's as if some sort of charge is being held (or accumulated over a few days) or some sort of capacitive action is taking place somehow.I decided to try the neg cable because the last time I took it to autozone, the alternator checked out okay on their machine (but off the vehicle).
Anyone run into a problem like this in the past? Where a good alternator/regulator seems to build up some sort of charge and won't operate properly? TIA
