    Default charging problem

    i have a 1990 k1500 2wd with a 350. I put a new alternator on and i still have a low reading gauge. I put a new batt. In and still same thing. Its only reading about 9-10. It seems to only do this when its cold.i had the alt. Bench tested and its fine.when its on the truck it tests bad. Anyone have any ideas
