SX/SXi/SXi Pro wiring qustion!

[overkill131313]

I just installed a full auto bilge pump but it takes power even when it is not running because of the water sensing switch.......so Im looking for a power wire that has 12 volts when the engine is running but zero volts when engine is off........can anyone tell me what color wire and where to find it on a 97 750 sxi?

u can simplify it by just putting a waterproof switch on the dash, or under the hood. or if u can get one of those bilge switches that mounts to the handlebars, and use that as a on/off power to ur bilge setup. i used a Water Witch set up for my bilge. its a water sensing switch that u wire ur pump to. it only draws power when the pump is on. (the water completes teh circuit between the sensors)

I could put a switch but I dont want to.....I want to find a power wire and keep it simple and less parts to go wrong......there must be a wire that has power when the engine is running........kinda like a headlight on a snowmobile.......goes on when engine is running......goes out when engine shuts off......simple and easy! I might have to buy a service manual to look at a wiring diagram.....anyone have one?

The one big problem with your idea is that you need your bilge pump to work in the worst possible scenarios, including times when your engine is not running. At the very least I would reccommend a 3 position rotary switch that could be wired on/off/auto with auto being the way you are thinking and on being straight from the battery. I just hope you have a crystal ball to have it in the right position at the right time. Your bilge pump is emergency insurance and it needs to function when absolutely nothing else will.

I agree with the switch... I almost lost my 750 because the bilge malfunctioned... use a switch...

Or disconnect the wire when you are not riding so you don't kill the battery. Bottom line, the bilge needs to be able to work even when the engine is off.

^^ bottom line- for sure.

I've always used a simple on/off switch from Oreily's/Murrays Auto that is not waterproof. Never had any issues, $3.00. Glued it (with 'Goop' awesome stuff) on my bars. Small, out of the way, easily hit with thumb.

use a switch, keep it simple. You also have to remember that any hot wire when the motor is running is not designed to have more amps pulled through it, you could cause problems tapping into the stock wiring.

This is also true. The lighting coil on a skidoo stator is designed to power the headlight and other accessories, the charging coil on a jetski is not. You could get around that by using a relay but that also defeats the whole concept of a clean and simple install with fewer parts to go bad.

This topic has been covered to great extent in numerous threads already and nothing has been found to be simpler than adding a switch. Now, what switch to use, that is an entirely different debate and one that I am completely biased on. :biggrin:

my brothers superjet just has a fuse holder right at the battery that the auto bilge pump is wired to. when he launches his ski, he pulls the hood, double checks everything and pops in the fuse...when he's done for the day, we store out skis with the hoods off so they air out, and he pulls the fuse out. pretty simple.

OCD makes some clean wiring kits(among other things aswell), i don't own any of them, but i know from the pictures they are top notch
