2015 Ranger Z119C
I have been noticing a ton of electrolysis on my new to me 2015 ranger z119c. I see it all over, jack plate, zinc plates, trolling motor lower unit housing. And even most recently, on the screws of my mega 360 transducer.
The boat has a factory installed jumpstart switch on the 3 battery system. One cranking, and two TM batteries. I noticed 2 things that seem to contradict the wiring diagram for the switch.
1. The grounding strap goes from the negative post on the cranking battery, over to the negative post on the battery that is supplying positive to the TM. As per the diagram, ground strap should go to the negative post on the battery that is supplying the negative to the trolling motor.
2. The Batt 2 wiring coming from the switch goes to the positive post of the battery that is supplying positive to the trolling motor. As per the diagram, this batt 2 wire should be on the positive post of the battery that is supplying negative to the trolling motor.
So both ground strap and batt 2 wire from switch are on the TM battery that is supplying the positive up to the bow. From looking at the diagram, and reading the specific notes, I am thinking I need to move both of these to the other TM battery, the one that is supplying the negative to the bow.
Can anybody confirm this setup, and if it may be causing my electrolysis?
Thanks!
