Lights Dim With Electric Window Operation
I noticed last night when pulling in to the drive, that my headlights dimmed when I "rolled up" the windows. I've never noticed this before and I haven't experienced any battery related probelms (cold starts are not a problem). So would this be the sign of a failing battery or alternator?
When I say they dimmed, it was really noticeable.
Thanks

If this is when your Ex was running it may be regulator built into your alt, or at least they used to be. Check voltage of both batts whe the truck is off then when its running then check it while running an turn on headlights and let us know what you find
