hey, i have a fan on a switch instead of the computer because i removed the computer and I bought a 50amp switch because all the other ones keep burning out and the 50 amp is burning out to...what could this be..i have the positive and negitive going to the battery..please help

 

I have two questions. 1. How is your fan wired? 2.Why do you have both sides of the switch hooked to the battery?

 

the 2 fan wires go to the battery and the the switches wires go from the battery to the switch...how should i wire them up

 

You need to use a relay. You are putting too much of a load on your wiring. There was a post that showed a diagram somewhee.

 

Like said above, the switch is only meant to pass a few hundered milliamps at most. Youll need to use a relay to turn the fan on and off. You can use a normally open relay rated for at least 25A from an autoparts store or something if the original wiring/relay is gone or damaged. The fan switch can then be wired to control the relay instead. Also dont forget to add a fuse if your using your own wiring.

 

so do i get the gm relay or 1 in like the help section and how would i wire it up

 

You can wire a fan without a relay. A relay is just a sort of remote switch anyway so that you do not have to travel higher amperages inside of the car or wherever. If you have both a positive and a negative going to the switch then you have a problem. An electrical switch is installed on one side or the other of the current. A relay may be a better option but if you really don't know how to do that then one way to wire your fan would be to run a positive wire to the switch then run a wire comming out of the switch to the positive on the fan and then of course run your negative on the fan to a good ground. You could even run the negative to the battery terminal itself but that would ruin the whole purpose of having a negative ground which is to save a mess of wires. Relays are not that hard either. They just require and extra circuit to be run.
