Hi,
Has anyone had this happen or have suggestions?
I was driving home about 2 miles from the house, and all of a sudden the following happened
ABS light came on solid
Both the brake light and battery light started fluttering on and off rapidly
The A/C blower spun down for a second and came right back on
My radio volume got very low (I assume the amp shut down)
I finally thought to look down at my ScanGauge and the voltage was fluctuating from 18.3-19 volts

The voltage regulator is in the alternator. I found that overcharging can also be caused by old oily brushes in the alternator and the voltage regulator can be fine. If you are really handy you can replace the voltage regulator yourself. But if you need to keep your truck in service, I would pull an alternator at a junkyard, get it tested, and then put it in. You can take your old alternator to a rebuild shop to be properly cleaned and diagnosed. Sent from my SM-N950U using Tapatalk
