Currently has a brand new N3221 voltage regulator (2012 vintage I believe - was new in the box with papers). The truck had a 2013 regulator when I picked it up in Houston. It died about 100 miles from Portland - 2600 miles into the trip back. I put in the brand new spare and drove the last 100 miles home without problems (other than the blown up air compressor - a story for another time - check your dryer cartridges kids). I did find some loose battery terminals after I got it home. All of those are fixed.
Start up the truck and both voltage gauges go to green (28v and the 14v gauge usually reads about 13.5v).
Drive the truck around - a couple miles or so. Gauges go to 24 and about 11.5.
Turn it off and immediately restart - gauges go right back up to green.
Is this intended operation for the 260a alternator and N3221 voltage regulator? I can't find any TM's that are applicable - anyone know of any?
Thanks!
