You guys with Ultragauge, Scangauge, etc, what voltage do you see at idle? I used to think I would see over 13v, but today I was only seeing 12.2-12.5v at idle. Seems a little low to me, I know that these old alternators are not rated very high, and I do have a 20gph water pump and fan running all the time.
I am at 154,500 miles and original alternator, just wondering if it is getting tired. I need to get everything pretty much 100% in the next 2-3 months.
