So the Chevy seems to be running fine right now, but I do have a question about our other daily driver ('92 Pathfinder) and thought someone could help - it's an electrical question.
At idle, the voltage gauge drops slightly and the dash lights dim, fan slows slightly, etc. Upon acceleration, everything picks up again. I know the battery is old, or should I be concentrating my efforts on the alternator????
Or, do I just get rid of it and get another Chevy

.
Any thoughts?
