How to wire a condenser fan to battery directly? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

My aircondition condenser fan stopped working. I checked circuitry and found the line between condenser fan relay and the air conditioner fuse inside driver's seat has no continuity. I don't want to go through changing entire super junction harness or replacing a wire inside the harness. I would like to hard wire this condenser fan to battery like the way SR people would wire their flexilite radiator fan on to the battery.

I would like to know how to do this. Does any one have schematic for this? What kind of relay and wire and switch do I need to get? I am pretty much new to electricals.

use a relay, Draw power from the battery, use the fuel pump as a trigger. You can even hide the relay in the fuse box (just take out the ac relay if you have no ac) That is what I did.

Thanks a lot for the reply.
What type of relay should I get? What do you mean by "using fuel pump as a trigger"? I thought I had to install a switch.

He means just wire it so it starts up when the fuel pump turns on...so that way the fan turns on when you start the engine. You can just install a switch to (what I did)...but then you have to remember to turn it off and on.

mRclARK1, Thanks for the reply. I get the idea. Do you have a simple schematic of how you wired it up? I am a totally new to electricals so I can't understand FSM's schematics.
