I have a 2011 skeeter ZX 200 with a minn Kota 3 bank on board charging system. I replaced both trolling motor batteries 2 years ago. When plugged in the number 1 and 3 batteries show full charge and light is green. However, the number 2 battery yellow light stays on. I have changed the in line fuse holder and checked the battery which shows 12.75 volts. Is it not charging right or could there be a malfunction with the light?
Any help would be greatly appreciated.
