I just drove home from visiting friends. I live in a rural area and there was NO traffic sighted at 1:15 a.m. About 6-8 miles from home I suddenly had all my lights(dash lights included) and stereo system totally cut out. Power restored quickly, but it cut out a few more times. I struggled to get the cd player to shut off and turned off my fog lights, and finally assessed the situation. I noticed my engine had not stumbled at all but strangely was running hotter than before, and my voltage gauge had dropped to just above the first line. I figured my alternator was failing, but I couldn't explain why my engine had heated up so much. The temperature was at or below 0 and I've been lucky to see the temp gauge rise even to the R while on the highway. When I finally made it back to town I noticed my voltage gauge had risen back to its normal position and the temperature was normal. Cut to the end of the trip, I checked under the hood with my flashlight but didn't see ANYTHING out of the ordinary. WHAT HAPPENED on my trip home tonight???? It scared the hell out of me. I have a few ideas but I want to see what you people can suggest first. Thank you.
