This increases the risk of depleting the battery used to start the main engine.

And at 4 amps charging, it will be difficult to bring both batteries up in between consecutive days of use.

I decided to go with the addition of a MinnKota MK110PC single bank 10-amp on-board charger for the 5th battery, wired to a splitter connected to the existing charge receptacle on the boat. So plug one cord in and all 5 batteries get charged.

Most reliable solution in my opinion, and still fairly simple.

Thanks for all the feedback, interesting info about today’s “isolators”really being “combiners”.

I agree, it's like a commercial for E-TEC G2 that don't have this problem.

I had the same problem as you do. My main problem was the battery was constantly draining when I touched the steering wheel with the electronic steering. I too installed an isolator, ran a negative battery cable across the start and kicker battery. Placed a trickle charger on the start battery and carried a small jumper cable to jump across starter and kicker battery in case of emergencies. After the installation of the isloator my problem was solved. I have diagrams of the installation for an isolator if needed. Good Luck
