Hi
I purchased a electric magnum metal downrigger for my 220CC earlier this spring. I loved the way it worked so I purchased another one to put on the other side of the boat.When I purchased my 220 it came with two starting batteries and your typical 1-2 both battery switch.
So I wired the plug outlet for the first downrigger I as per instructions that came with the downrigger. I ran 8 awg wire and installed a positive and negative bus to hook up multiple downriggers with and 40 amp breaker. I hooked the Positive bus up to the battery switch out going terminal so the down rigger would be running on the battery I had selected on the switch. This worked fine with one downrigger.
But now I’m adding a second one I’m concerned with the outboard alternator being able to keep up with charging the battery while slow trolling. Also if we happen to start both of the downriggers at the same time it might make the MFD reboot. The motors on the downriggers pull 15amp but starting it can be up to 40 amp depending the weight size we are using. It works on a clutch system so it’s only pulling power when raising and lowering the weight.
Ive already swapped out one of the starting batteries with a group 31 deep cycle. I really want to avoid having three batteries if all possible there is not much room on the tray and I had a time getting the larger deep cycle through the bilge access door. I thought I was going to have to remove the ski piling to get it in but I made it fit. So now my plan is to hook the DC battery to the #2 terminal on the battery switch leave a starting battery on #1 terminal. Leaving the starting cables and Acc to the output terminal. Then put the downrigger bus on #2 terminal instead of directly to battery not to have a long run to the breaker. I have some 8 awg wire left over so I plan on making a jumper from the aux charging cable on the outboard to the DC battery with a 40amp fuse on both ends.
So what I’m planning on doing is leave the battery switch in position 1 for starting and running the acc (pumps , MFD, etc) while the outboard is running. And having the downriggers isolated to the DC battery while charging the DC battery off the aux charging cable. And if I’m anchored without the outboard running for a while being able to swap battery switch over to position 2 to run ACC on the DC battery.
So my question is does this sound like a good idea or should I go about this a different way? Does anyone think I need to use three batteries or will I be ok with two? Any advice will be greatly appreciate thanks.
