Headlights dimming or go off
1993 3L Ranger. A few days ago my headlights went out suddendly then came back on a few seconds later. This happened twice on same short drive. No repeat yet.
Next day I noticed that headlights dimmed when I slowed to take a corner. Is my alternator failing?
We've had a lot of rain lately and I was suspiciuous that electronics in cab may have gotten a little damp due to rain intrusion into cab.
