None of these features change with additional circuit loading (e.g., turning on the headlights), nor with engine rpm. This doesn't sound to me like a voltage regulator problem. I wonder if I've got an active load of some sort pulling on the electrical generation system, such as my DC > DC battery charger which can haul up to 15A out of the system for charging the deep cycle house battery. I'm going to plug the van into the household Mains and let my onboard battery charger take the deep cycle to 100% and see if the surging occurs with a full house battery. -- Mike "Rocket J Squirrel" Elliott 84 Westfalia: Mellow Yellow ("The Electrical Banana") 74 Westrailia: (Ladybug Trailer company, San Juan Capistrano, Calif.)
