I am having a problem with my new battery going dead. Checked everything and am down to the voltage regulator, the red wire is always hot and when i unplug it the volt drain is off. Is this a possible bad regulator?
I had the new AGM battery go dead on my 02 400Sportsman this summer and what i found was the red pos going to the battery from the regulator in the front of the radiator was draining the battery. My fix after finding the regulator was on BO was to run the pos wire from the regulator to the IGN switch for a switched circuit instead of the battery. Works like a charm.
I wired my old regulator to the ign switch in 2009 and have had no problems since. Polaris really was out to lunch on this issue never should it have been wired to the battery. My new regulator sits on the shelf to this day.
