dual bilge wiring question

not sure of how the wiring goes for duals- so far i grounded the 2 negs from the bilge, then i beleive i connect the 2 bilge positives to the positve wire on the switch and hook that to the positive on the battery? i then put the switch neg wire to the battery neg, bilges just run continously w no switch action-
it works if i connect the 2 pos bilge wires to the neg wire on the switch and then that to the pos on the battery- if that works is that ok? i wont burn anything up will i? because the elec diag shows it how i tried originally and it didnt work
-im an idiot on elec!!!

What switch are you running ?
Why would the switch require a negative wire unless it has a light or something ??

It's always better to switch the negative side of the bilge pump circuit as it reduces the chance of an electric shock when riding in salt.

Don't look at the colors on the switch.

What I would do,
Run a wire from battery positive terminal to a fuse holder (make this wire as short as possible)
From the fuse holder run the wire to both bilge rumps (depending on pump that would be the black wire but make sure the pumps are spinning the right way)
From the pumps run the brown wire to your switch (doesn't matter which color wire you use on the switch)
From the switch, run the other wire to battery.

Test system and go ride.
 
thanks alot- what size fuse did u use?

The bilge switch does not have a positive and a negitive. It has an in and an out.

You hook your negitive from the bilge to the white bilge switch wire and then you hook the black bilge switch wire to the negitive battery terminal.

The positive bilge wire goes straight to the positive battery terminal with an inline fuse (I am using 5 amp mini fuses in sealed terminals).

The positive is always connected. The switch causes a break in the negitive connection.

The fuse is necessary because if comething gets caught in the bilge and it over heats, the fuse will blow. If you didn't have a fuse, the bilge would continue to heat until it ignighted.
