Home test on the Alt showed it to be putting out 13.2v, just barely enough to give the battery a surface charge.
Took it to AZ to have them test it on their portable tester. It showed the battery to be good, and the ALT passed all tests. I told them about the low voltage output, and they said to remove it and they would bench test it, as that machine gives better results.
So I did. It tested to be good. It read 16.4 at its peak output, and 14.2 at it's lowest. Tested 3 times with same results. I installed it back on, and now need to test other things.
On another note....
Spring testing the rig with some paint I have to relocate since I am moving.
Springs are squatted so low, I can't pull the trailer loaded with more paint.
