Battery light problem
I have 99 GMC Sierra 4.8 I can drive and my
battery light comes on I lose no power my gauges
drop but everything still works Any Idea I was
thinking of changing the switch ?
Is your battery good? I would have it tested. Clean the battery terminals and cable ends while you are at it.
Sounds like an alternator problem. The light comes on when the system is discharging rather than charging.
