try unhooking your negative battery terminal then hooking it back up. itll reset all your radio stations if that isnt a big hassle for you but that usually works for me when i have lights turn on for no reason then they go back off. it might just be a minor glitch.

I also have a GM vehicle around that age, and i also have dual alts. I get a flicker of the battery light once in a blue moon. I haven't really narrowed down the source of the problem, but I haven't gotten it since i have been experimenting with various belt length vs idler pulley diameters. if you're under the hood, do you hear any belt slippage? Does the tensioner move a lot?

thanks for replies new belt and tensioner was installed same time as alternators. I'll try disconnecting battery wires again .thanks
