Hello
I have a 16' aluminum fishing boat with a Johnson 4 stroke 15 HP ob. This motor has an "unregulated" charger built in.
I have run extra heavy battery cables from the motor to a single 12v Optima Blue Top battery that I have mounted in the bow of my boat (weight forward).
I run a 12v Minnkota 45 or 50 on my bow, forward and aft fishfinders and an Eagle Intelimap GPS.
I like the setup because I can troll with my electric for an hour or so, then fire up my ob and it charges my single battery. I like not having the extra weight/lack of space with additional batteries.
However, on my last fishing trip, the rectifier in my ob burned up and had to be replaced. A friend told me this happened because I needed to run 2 batteries, a starting battery and a deep cycle for my trolling motor.
Is this a correct statement?
I like firing up the ob and having it charge my only battery. But is my built in charger being overworked? Why would it fry the rectifier? Is an unregulated charger a problem or do I need to be concerned with what I'm doing
Confused..
