radiator fan

[jnr 13b]

hi all

I change my radiator on the weekend.
I finich putting the thermo fan on today.
I found a ignition switch cable under the fuse box in the engine bay.
I put a 15amps fuse on the cable and run it straght to the thermo fan.
ground go direct to the fan.

everthing work find. the cable does not heat up of anything like that.

but when i turn off the car. the engine still stay on for about 2 second.wtf.

I take the 15amps fuse out, start the engine then the car off it was back to normal.


so the 2 seconds delay only happen when the thermo fan is working.

what is wrong with the car. help help me

try using a 4 pin relay..use that 12v as a signal..and use a direct feed off the battery for the fan..might want to get some 30amp cable though..just incase..15 should be fine though
