I have a 3 year old bass tracker. Just put in new trolling motor battery in February. Always keep it plugged in my garage. Went to the lake recently, and I had very little power for the trolling motor (ruined day of fishing). When I got home, i plugged in the charger but the red light did not come on. Doesn't seem to be taking a charge. A green light comes on, but not the red one. I checked the extension cord and it works.
Any thoughts? How do I figure out if it is battery problem or charger?
