supra 21v ballast wont empty
 

Hi all,

Having an issue with the ballast not draining. Triple ballast, front and right drains no issue, left no go. Blown 5amp fuse. Replace with good 5amp fuse and the left drains for about 5 seconds then blows. Tried to reset main ballast fuses, nothing changes. Any advise would be great. Thanks

what year? if it has the seperate pumps for empty replace that pump it is blown and shorting thats why it keeps popping the fuse.

07

2 of 3 ballast empty no prb. 1 fill and 1 empty pump setup with the sprinkler valve ghetto setup is what I have.

This happend with one of the pumps on my moomba which has the same ballast system as your supra. It would keep blowing fuses every couple times out until it finally stopped working all together. Rplaced it and everything is good.

Bad pump motors increasing amp draw causing fuses to pop. Replace pumps.

Bummer, was hoping for something else, thanks guys for the response.

i've been through about 8 of those pumps on my 07....

John 8, that sucks. Something causing a short or crappy pumps?

when those pumps blow it is usually caused by 2 things, being run dry for an extended period or something obstructing the flow.
