Congrats on the new boat. do the lights come on in the left/right switches. all three bags should fill from the same fill pump. empty pumps are seperate. do the mpty sitch run and make noise?

I am in the process of getting the GI to GIII upgrade DIY style so i have been accumulating parts.

There is a single fill pump that goes to the sprinkler valves( under the rear seat v drive area) each switch LRC will fill the respective bags by turning on the pump and opening the valve to each. when you empty each LRC bag the switch turns on the evac pump at each bag.

I guess i would check all the connections behind the switch, then feel the empty pumps it they run while emptying ( run only for a few seconds to check) then check the elactrical connections at the sprinkler valves to make sure they are tight.

does the fill pump run when the LR switches are flipped to fill and just no water enters the bag?

Valve look like this below

If it is a stock GIII system it should not work that way. Check the sprinkler valves. There is a little switch on them that is known to get flipped off accidently. Your owners manual makes note of these switches on the sprinkler valves. If you don't have an owners manual, I believe you can access the online version through the links all the way at the top of this website. Possibly under "About Moomba"?

Good luck and congrats on the purchase.

2007 Outback v, forgot about those switches as well. Page 40 in the manual below

Do you switches look like this with just a different logo


04-01-2010, 07:12 PM
yes they look exactly like that..... any idea whats going on ??

Read page 40 in the above lnk to the manual it should explain the overide lever on your soleinoid valves and or the breaker for the switch panel. I think its the levers

I tried to cut and paste page 40 from the manual but was able to.

alright gang i need some help......btw my sprinker valve system looks identical to the picture above........i looked at the switches that are in the first pick they are switched to on and still when i hit the left or right drain or fill switch you can not hear the pumps or anything running but when i hit the center fill or drain you can hear it working.....all the lights come on when i hit any of the switches just nothing happens when i hit left or right....how many pumps does an outback v have i only see one? could one of them gone bad or be blown? if there is only one why does it work for the center and not the left or right
i checked all the connections behind the switches and on the valves
anyone have any ideas,advice any help

This isn't all bad as the center switch is actually switching on the fill pump that all three switches use. That means the fill pump actually works. It sounds like a fuse to me, or even two fuses.

If its not a fuse, check on the backside of the switchs and make sure all the wires are pluged in. Think all 3 switch's have a wire going into a relay that turns the fill pump on.
