Rite i have a problem. Only a small one though.

The radiator fan is wired directly to the conncetor in the engine bay, where the battery used connect to. Which is now connceted straight to the battery in the boot. Then there is a switch, on a long strech of wire in the car, which is connected to the negative wire of the fan.

When the fan is off, it runs fine. Idles like a champ, and has no problems. As soon as i switch it on, it starts to missfire and wont idle at all.

I orginally thought it was a drain, but none of the wires get hot, and the head lights, dash lights and interior light dont dim at all. Any ideas chaps??
