3 Alternators and 2 Batteries within 3 months -- Need Help Please :)
My car is going thru alternators and batteries. No aftermarket accessories. The load seems to be too much for the alternator when I accelerate or pull a lightweight trailer. We have gone thru 3 alternators and 2 batteries in the past 3 months. When I accelerator aggressively the battery light will flash for a few seconds. If I am pulling the trailer, it flashes off and one most of the trip.
It's unlikely that the batteries and alternators themselves were at fault. Someone will have to test and prove what is occurring that is causing the symptom as described. Does the battery end up being discharged sufficiently to cause the car to not start? Have you confirmed that both battery cables and the charging output cables are good at both ends? (not just the battery ends)
