Thanks, and wow you're right lots to read,
Looking at some of the issues people are having I went back and tested the output at the alternator and it was 0. Just the 11.4 volts that was the same as the battery which is way to low. This alternator has less than 10 hrs and was installed new several years ago. Put in a new one and am now getting 13.4 volts. Must be the Lake Havasu heat, 117 today😅
Thanks for the answer, this is a great site.
