Let us know what you find out. If you did an ohm test, did you also do a volt test from the post on the alt to ground?
Yes. The only batt charger i have is for my quads so was taking forever but got the batt charged fired up at at almost 12v would drop slowly about .01 volts every 1-2 seconds or so . Turn on the a/c and lights and would drop faster. Thats testing on the post on the alt. Im gonna drop the battery off tomorrow to get fully charged and tested as well. The truck doesnt have a lot of miles but its been abused since new by her ex husband.
Alternator was bad. Put the new one from oreillys on it and good to go . But now either the fan bearing are bad or theres a bent blade. Truck vibrates really bad when the fan kicks on . Gonna go through that tomorrow.
