Went deeply into manual I down loaded 9 yrs ago. Found little blurb about an off/on switch that activates a trickle charge [3 amps] if desired to be used. No drawing where the switch is located. Also mentioned that if starter batt is charged by other means then no need to activate the charge feature. Kind of seemed in the "wording" that this charge feature might not be functioning. So, I guess, similar to as I alluded to in post #1... the PO must have set up the solar panel just for this reason. Guess the fact that one of the solar leads to one of the batt terminals had unknown to me broken off was reason for starter batt eventually going dead. Now that I have solar hooked back up, the batt will likely remain charged.
In addition, I have a 2 amp trickle charger that activates whenever the boat's 110 AC switch is on. It keeps my completely isolated emergency G27 batt charged... and it is not too far from the gen set batt. Therefore as added precaution [help in keeping gen set batt charged] I plan to run lead from the emergency batt trickle charger to also include a charging feature for the gen set batt.
Thanks for the input!
