My coach has a HEHR Powerline alternator with an external regulator. It uses a Ford voltage regulator. I was told by the pevious owner that the alternator was upgraded to 200 amps and I replaced the NAPA regulator with a genuine Motorcraft unit.
I've noticed a voltage fluctuation issue with this. It bounces between 13 and 14 volts.
I was told by Monaco to consider upgrading it to a Leece Neville alternator. I wouldn't mind putting a Ford alternator in it. :p
Have you verified this independently, with a separate digital voltmeter?
Are your batteries staying properly charged?
Is your alternator causing you any specific problems?
is no to any, particularly the last, what are you worried about?
