Sea-Doo Switch Dual Battery Kit With Switch

Peace of mind being on the water, knowing my Switch will start every time no matter what accessories are on while the boat is off.

It has everything except some foam blocks for the battery to keep it tite in the holder. You will also need zip ties.
And the instructions aren't very helpful, look for a video on line.
Took me about 1 hr to install and seems to work well.

The installation video was a huge help, but after installation the 1 battery position was not providing power. The cable harness is very tight inside the switch box with the 3 cables, and the compression of the original battery cable inside the box was not allowing the circuit to work. Trimming a small portion of the box was necessary to allow enough room for the cable turn.

Installed on a 2024 Sea-Doo Switch 21'
The switch wasn't wired properly itself, but if the rear 3 terminals on the back of the switch were highlighted so you can see the labeling, all you would need is a simple list/diagram of where each terminal wire goes.
The red cable going to the primary battery needs to be a few inches longer. Primary bat cable is across the top of the battery instead of going around properly.
The black negative cable going to the secondary battery needs to be a few inches longer, I had to separate the two so I could stretch more to make it work. I had trouble getting both to fit properly.
The tie-down strap could be about 8-10 inches longer so you could use the boat support holes to strap down left to right. Or you could leave the strap kit you provide to use as intended and add another strap only so you could use the boat support holes too. This way the battery is tied down left to right and across the center. These are simple...just my thoughts.
