Alternator - regulator mismatch?

This thread cursed me....

Tonight while driving about 15 minutes from home the alternator quit charging altogether.

It was night so lights were on. Battery was able to supply 11.1v to the system. I knew I had enough juice to get home but to be safe I put it in park and turned off the head lights at stop lights.

5 minutes from home it all started charging again!

After Christmas I'll be running down the problem.

Merry Christmas all
