Great video James.

Thanks, I appreciate the feedback!

Very informative, thank you.

Thanks, glad it helped!

Thanks for the video. Can you explain how you wired your onboard charger to go to house batteries and trolling motor bank? Also do you have a way to draw from your trolling motor batteries if your house dies?

[@jamesjr1987]

Hey Dian, I have an extension cord that both of the onboard chargers plug into that both splice into the same shore power port. There's a 3 bank mounted in the forward trolling motor battery compartment and then the 2 bank charger for the rear is in the console.

@@jamesjr1987 got it that’s what I was looking to do with mine. Now I just need to figure out how to pull all the chords/cables through to the compartments. Thanks for all the info.

Are your house battery and engine battery identical types? I would love to hear pros and cons of deep cycle vs. standard.

[@jamesjr1987]

Having them both AGM is the most costly but best (more vibration resistant, longer life, etc), despite Suzuki's owners manual implying AGM's can't be used. You can also go with 1 cranking and one deep cycle battery as well. Or go all in and use lithium for weight savings and longevity.? The only thing I wouldn't do is use a deep cycle for cranking battery, or use a cranking battery for the house electronics. The other options are somewhat of a sliding scale between $$$ and weight/longevity

So does that mean in the "on" position unless I have a bad battery if the motor is running it will charge both? I trolled with the big motor for 5 hours in the combined position and the simrad eventually died. Motor still started. Very confusing. Should I have left it in the on position?

[@jamesjr1987]

If you leave it in the "on" position, the motor will charge both as long as one is not 100% dead. The ACR will bridge the two after 30-45 seconds of the motor running once the voltage has gone up. Simrad is very finicky with low voltage, so you got very lucky the motor started. In the future you want to troll in On so that the electronics do not impact the starting battery. These are really good Facebook groups to join, first is the unofficial group and second is the official group with more factory people monitoring it. Any questions like this you'll get lots of answers! facebook.com/groups/2022889891153660 facebook.com/groups/628226224233999

My 248 has 2 cranking batteries. If I just swap the port side one for a deep cycle is it identical wiring?

[@jamesjr1987]

It is. You might want to consider an AGM instead, better vibration resistance and still has enough CCA to handle most all outboards.

@@jamesjr1987 right on. I noticed you have 2 bilge wires bypassing the battery switch, I am troubleshooting my manual bilge switch not running, did you rewire that or is that how it was from the factory?

[@jamesjr1987]

@@ianbraddock2945 I added the 2nd bilge pump. The dealer wires up the batteries and bilge after delivery from the factory, but they SHOULD have bypassed the switch for the bilge pump. If they did or not can depend on the dealership

[@ianbraddock2945]

@@jamesjr1987 gotcha. Mine was working fine but went out in some rough weather and it's not working now. I traced from the switch to the pump and everything is connected, but I can't find where the wire goes from the switch to the battery

[@jamesjr1987]

@@ianbraddock2945 the wire should go directly to the battery and not the switch. If it goes to the switch that's an issue as it wouldn't pump out if you left it docked overnight
