[QUOTE=babyhuey;16624] Have replaced around 10-12 alternators on Tributes. Mostly older 01's. One other thing I have seen that caused a charge light on when output from alternator was normal. Take the cover off of the under hood fuse/relay box there by the battery. At the front inner corner area you will see two large diameter wires entering the fuse box from below and held into place on the mounting lugs with 10mm nuts. See pic below. Check to make sure that both of these nuts are tight and there is no corrosion on them. Those two wires are the connection point between the alternator and battery. Loose connection here will cause a voltage/amperage drop that has been known to cause undercharging and charge light on. Also check the 15 Amp ALT or #11 fuse in that same fuse box. Should be a fuse diagram on the underside of fuse cover to help locate. Otherwise just need to be able to go off of voltage and amperage outputs from alternator to determine if it is ok. Assume this is what was checked by the auto-electrician [QUOTE]
