OK got my jumper wires replaced... Used some 4 gauge golf cart jumpers I had in the garage. Now I think that two of my three batteries may be going south. After charging all three batteries separately I have readings of 12.9, 12.3, 12.4.
I went ahead and hooked them all back up so I can see what my voltage was going to be after sitting for a week. First hooked back up, voltage was at 12.6, now it has dropped to 12.2. Disconnect has been off, so nominal draw from the level up system.
What I have been reading is that the 12.9 battery is still good and the other two may be near end of life?
Any info/insight would be greatly appreciated. Have one more trip next week before we put her up for the winter. So have time to get some new batteries if I need to for next season. Will be going with 4 6 volts next time!
