Engine shutoff during ballast fill

[sandm]

not sure what your end goal is. I would decide at this point what you want long term for upgrades and then plan how to attack this issue. if it was my boat I would be planning a 3 pump fill and drain setup. that said I would wire the pumps outside of the ignition circuit. if your boat is like my '06 supra was, there should be a positive buss bar under the dash. hook onto that and wire the pump thru it's own circuit/breaker.

You may have a common connection between the ground of the pump and your ignition circuitry that in turn has a poor ground to your battery ground. When you turn on your pump, there is a high enough voltage potential applied to the negative wires to drop out your ignition circuit. You should see a reduction in pump speed if this occurs. Check the continuity of your ground wire to the terminal block.

Well I went and wired the the feed wire for the pump/valves up and hooked it into the hot bus. It has its own distinct ground wire going to the grounding buss, the ground appears okay, I havnt’ plopped the boat in the water yet, but from my examinations without turning the boat all the way on, it appears to work, only time will tell I guess. I probably should wire in a breaker for it, but it does have fuses so I’m not that worried.

I intend on getting reversible pumps and completely redoing the system, but one step at a time. I had 350lb bags in each rear locker and 400-450 in the center locker, I just ordered the dual 910lb bags from wakeshapers for the rear as well as the reinforcing bars for the engine divider. Might stick those 350’s up front for temporary.

Actually those fuses under the dash are for the drain pumps and the sprinkler valves. 3amp is for the sprinkler and the 10amp are for the drain pumps. The main fill pump has a resetable circuit breaker located right next to the fill/drain switches. I believe it’s 25amps. Your circuit is there and not at the fuse panel so I’m not sure you changed anything. I’m thinking like others mentioned that you have a ground issue.

Hmmm I will look again to be sure, but I do think I changed something, because it used to be, even with the key out of the ignition, you could still turn the pumps (both fill and empty) on and off, now it only works when the key is in the run position. But that makes sense about the 10 amp drain fuses, I will look for a 25 amp circuit.

That is normal to run the pumps with the key off. Just like the stereo. I wouldn’t want my pumps running on the ignition because the hour meter runs with the ignition on.

Well what I mean by that is I only ever fill the tanks when the boat engine is on, most of the time idling while I go to park the trailer and the better half waits for me to come down the dock, so I’m okay with them only running when the boat is on. I don’t want a switch accidentally getting pushed and the motors running dry and running the battery down while I’m trailering the boat, so I consider it an improvement (the fill motor is actually very quiet). I will look again, but I didn’t see a fuse or a breaker near the fill switches though

I have looked and the ballast system has its own distinct grounding wire different than the ignition system and it’s tight and doesn’t seem to have any issues, actually now the ballast system is completely separate from touching the ignition system on both positive and negative side, except they both touch the positive bus and negative bus coming from the battery of course.

That’s interesting. My 06 with gravity games has three switches and a circuit breaker on the panel. I assumed they were all like that. That’s what I get for assuming.

Yeah I think they skimped out on adding the last valve, it does have 3 tanks, but it kinda fills them all weirdly, combines two of them into one zone. Honestly if it had manual valves it would be so much easier because the electric ones don’t close all the way and so you basically get one bag filling slowly and the other bursting at the seams, kinda stupid.

I’m going to get the reversible pumps and my ultimate goals is to have 4 switches: front, middle, and left/right rear.
