Re: Lower Exchanger Electric Fan
If you do i would run a RELAY or you may have some melted wires or switch or both. if you run the pump and fan for any amount of time i would think they both would draw some high current

If you use the same ground wire and put a switch between the fans and the ground you should be ok. It is better to run two separate switches. Switch or no switch you still need a relay.

Re: Lower Exchanger Electric Fan
I have a fan and the pump wired to the same circuit.. the stock relay does not like this AT ALL.. it however does not blow the fuse on the back of the altenator.. So I removed the relay and I use a nice thick gauge wire jumpered in between two of the ports that the relay originally plugged into..
I drove my truck like this the ENTIRE trip to and from detroit.. only thing that sucks is that it is hot all the time so you have to pop the hood and remove it when you don't want it to run.. I will eventually wire something up so I don't have to jump it, but a small elec fan and a johnson pump shouldn't pull enough amperage to melt any wires just kill the relay..

Re: Lower Exchanger Electric Fan
i would have to agree but you could get 2 relays set them side by side and have the one switch control both
the only thing wiring a couple big eletrical devices on the same fuse is when they start they dont create enuff current to blow the fuse but as they run they get hot and the current draw goes up and can acually draw more amps than the fuse would normally allow (like on a short to ground you get a direct spike. were as here you get a gradual amperage increase) and that will melt those wires and the wires around it
hope that sounds good mainly all i am saying is dont over load any curciuts wearther it is fused or has a realy what ever. the wires to me are always the problem child
