I had seen some wierd fluctuation in my charging a couple weeks back, so I pulled my alternator to have it tested and it failed.
I bought a remanufactured alternator to try and remedy the problem, but what I am experiencing now I don't have an explaination for.
The charging system works fine (based on the stock guage) when I am running the radio and driving during the day. (not using the AC)
If I turn the AC on, it causes the charge to drop a letter. I am normally (pun intended) between the r and M of NORMAL on that guage, but when I turn the AC on, it drops to between the O and R. This is concerning enough, but if I run the AC at idle like in stopped traffic and a stop light, it dropps down to the N. When I go again, it raises back up to between the O and R.
Is this possibly a bad remanufactured alternator? I am thinking the voltage regulator is probably bad on it, but wanted to get someone elses opinion since this really isn't my specialty. When I examined the remanufactured alternator, it had the old motorcraft voltage regulator on it, so it was reused. This is what is leading me to believe this.
Is it possible the battery is getting weak?
The reason I ask about the battery is that if I run with the lights on, it too will cause the guage to go down to between the O and R, but after a while it goes back to the R and M.
Thanks,
Keith
