High Voltage/ Battery light stays on

by Gary Wingfeld
(Houston, TX USA)

Battery light staying on the time. I did not have this problem until I change out the alternator. The only reason I change it because the alternator shaft had a litter wobble to it. So I did replace it for that reason. I replace it and the bear was bad in the replacement alternator. So
I replace it again and now the battery light is staying on all the time.
We I check the gages on the dash it told me have voltage. When I put my meter on the negative side of the battery to the top of the alternator I'm getting .04 ohm's. When check the battery I was 17.7 volts. Both test was done while the engine was running with everything on and running 1800rpm.
I'm at a lost at this point. Even replace the battery as well. ANY suggestion. Gary
