I did my own installation and I'm not sure when this started, but recently noticed I was running out of power too soon on my 24v minn kota. I start the day with 2 full charged batteries. When I checked on the batteries after fishing one AM, one was still fully charged the other was around 3.0...
My 3 cyl 1989 Mercury 70 hp (ELPT0) OC134764 Model # 1070412GD works fine as long as I charge the battery myself.
Anything I can do to check it to determine what to do next?
