I'm Awesome
I just made a parts run with my 98 1500 4.3. It was about 60 miles each way and just before I got to the JY I noticed the voltmeter at about 12 volts. As I continued on it was slowly dropping like the alt wasn't charging. I came to a red light and when I stopped it jumped back to 14V. When driving off it dropped back down to about 12 and continued to fall. I got to the Junk Yard and left it idleing and charging close to 14v. I was there about half an hr and it was reading between 10 and 12 when I got back to leave I was down to almost 10 v. When driving away I noticed it would go back up when I took my foot off the throttle. I ended up making it all the way home by taking my foot off the gas and shifting to nuetral downhill and stopped at a rest area and let it idle for about 10 min.
Alt. is only 2 months old and was replaced due to bad bearings in the old on so I will replace it again Mon. on warrantee. I have never seen one that only charged at idle but not at higher rpm's
