Is your ballast switch on the dash connected to anything? My 05 came with center ballast only which was controlled from the switch on the dash. I ordered parts from Skiers to add factory Gravity 3. It came with 3 rocker switches and a fuse/relay board that provides power to the fill pump when any of the fill switches are on. My switch on the dash isn't connected to anything now.
Also in your pic of the circuit board under the dash the power feed wire with the ring lug is not secured with a nut.2005 Mobius LSV

Well I actually took the boat out on the weekend with the re-wire and it filled perfectly without shutting down, it filled very quickly, and empties very quickly, faster then before, so maybe it was getting enough juice? I saw my battery is a 24v battery, I hope that there isn’t some sort of wrong voltage and that’s why it was hooked up weird, I need to test to see how many volts the positive bus has, and how many the motor is supposed to add.
In answer to your question about the dash ballast button, yes it’s hooked up, but I don’t think it does anything, I’ve flipped it before and nothing happens

Engine shutoff during ballast fill
There’s NO WAY your battery is 24V. Not a chance. The electronics on Moombas are made to run on 12V, period.
How on earth did you come up with that idea?

Nvm, 24dc has to be the part number not the voltage...

You can wire the batteries in series and then you’d essentially have one 24V battery but everything would be fried when you turned it on.

You should move the ring lug from the large battery post clamps to the threaded battery posts for a much more secure connection. Your Neg connection looks to be a little loose.

Good point, that makes sense, I will check it.
So I need some help with some math, I guess I need to figure out how many amps 4 reversible pumps will draw on start up and continuously running, as well as figure out amp draw of the boat engine running, and then figure out how well my alternator is running, or do you have to upgrade alternator when you are only going to be running the pumps for 5 mins to fill tanks and have them off the rest of the time?

Shouldn't need to upgrade alternator. Most people are sitting with the motor off getting gear ready while ballast finishes filling. Use FLA rating on the pump motors to size wiring and fuses.
