4.0L electrical problems
Ok, my problem has been going on for going on several weeks now. When I rev my engine above 2500 rpm, the battery light begins to flicker. I thought maybe the serpentine belt was slipping at higher rpm, causing the battery light. My truck has died on me. So far I have installed a new serpentine belt, a new belt tensioner, and a new battery. I had the original alternator rebuilt. The guys who rebuilt it installed a new voltage regulator, 2 bearings, and a brush holder. The truck is doing better, and hasn't died on me again, yet. I am still getting a battery light above 2500 rpm. If it's at night time, the headlights do dim when the battery light is coming on. The connections to the alternator and the battery are fine, as far as I can tell. My Ranger is my only driveable vehicle, without it I can't get to work. Any ideas? The truck currently has 65,000 miles, and is in excellent condition. Thanks in advance for any advice!
