Ok, my alternator is only puting out a max of 12.5 volts, somtimes much less on the gage. I have new batteries and I have checked with a meter and checked all the wiring.
I have been looking at the DBelectric alternators and they seem to have good reviews. My old alternator has 3 wires plus ground. Do you guys recomend switching to the 1 wire setup? The original one is from 1994 and has the delco 155603 number on the tag.

I think I am going to try this one, it seem to be the closest match.

This is the one me and my friends use. Went from 3 wire to 1 wire and 105 amps.

Ordered the alternator, shipped the same day. Received it yesterday and installed it this morning. Reads 14.7v at the alternator, 14.6 at the batterys and 14v on the gage. Brand new, made in china but what is'nt, the old mando was made in Korea. Definally a good value, bolted up and wired just like the old one.
