Default IC Spray DIY wiring help

I wired the IC spray as fallows...


Power from battery to power on switch with (Inline fuse 30amp)
Then i did the neg batter terminal to the neg. on the washer pump..

then the power to the washer pump to the Accesory point on the switch..

then the ground from the switch to the bolt on the side of the car when the steering coloum pannel is dropped down..


My question is once i had this all set up and i flicked the switch the Fuse blew.. Is this because its only a 30 amp fuse? And the switch is 12v 32amp?


Does my wiring instructions sound right, and do you think i need a higher amp fuse, if so which one?
Also, on my 3 pin switch, one pin is a copper coller the rest are silver...

silver silver copper
and they are numbered 123... how do i know which one is the 12v power on the switch?

Wink Wrong wiring

Basically, what you are doing now is just grounding the fuse. Is your swich 4 legs or 3 ?

3 will be:
- Power IN
- Power OUT
- ACC

4 will be:
- Power IN
- Power OUT
- ACC
- Ground

1- If you are using a switch with ACC on it, then it is probably backlit at night. The ACC is only there to light the led inside the switch. You should wire the ACC with your wire from the let say cig lighter that has a variable voltage with the dimmer switch. The ground is for the light on your switch. Not for the pump. If you don't want the light to dimm, just wire it directly with your power source.

2- The way your system is set up, for sure you will blow your fuse. It should be:

- power from your battery to your switch (with your 30amp inline) "power IN";
- then another wire will run from "power OUT" to positive on the pump.
- Negative on the pump grounded on the car. (Try the ground screw next to the battery.)
3- 30 amps is a lot of juice. If this is what you drive, then you are probably running a serious garder sprayer, golf green type of thing. Your switch is rated to hold 32 amps. The pump is what draws power. Not the switch.

Hope this helps.

PM me if you need more details.
