My ’06 Sportsman has recently begun flashing a battery symbol at me. I had the battery tested and it is still good. I have to jump start the guad but it runs on it’s own. I tested the voltage after starting and had a reading of 16.4V. The icon and speed needle were both flashing. When the fan kicked on the voltage dropped to 15.6V and the flashing quit. The voltage didn’t go back up after that and when the fan kicked on the second time the voltage dropped to 14.5V with no flashing indicators then returned to 15.6 when the fan shut off. I checked at the ECM and had power at the red/white strip wire(third from the right top row) and at the red wire(4th from the right bottom row) I haven’t found a schematic online or a Youtube for this specific ATV. Any ideas what I should be focusing on?
BTW my low beams also quit working. I can measure battery power at the legs on the bulb when the switch is on and continuity across the legs too but no illumination. That is something that I have never experienced before. High beam and taillights work still. ????
