How many of us are there? Owners of Dodge based RV's?

I always thought the "ground the green" wire to full field the alternator was a good system on the old 2 wire solid state mopar regulator. Easy enough to diagnose also..;)
That ford 4 wire regulator does temperature compensation too i think, one coil was temp, the other alternator regulation inside. Or was one powering fields, and other reg?
Maybe where you are Griff the temp thing might be an improvement over just voltage regulation 13.5-14.1 depending on battery resistance with the Mopar unit
