Just thought I would post a couple of pics of my project to electric fan the old isuzu Bighorn.
After my last trip on the Selwyn river, where I put a hole in one of the radiator tubes, after the plastic Viscous fan decided to meet the radiator while fording, I decided to put in an electric fan that I could turn off while fording if I needed too
I got donated a radiator with fans on it so the Mod begins ;D
Here's a couple of Pic's of the current fan.
And a Pic of the donor radiator with both fans still on it.
So, I finally got some spare time (when the truck wasn't needed for daily duties) to pull the radiator out again, to have the thermoswitch thread put in it.
While the radiator was with the good buggers from Hornby Radiators I set about sorting out some of the wiring.
I know it's a bit back to front, but I started with the warning light.
The idea is that when you look to put the trucks feet in some water, you flick the switch to stop power going to the fan.
Now this poses a problem, it's bound to happen in the heat of battle (excuse the pun) :roll: that I could forget to turn the switch back on.
So we have a little red warning light as a reminder
Here is a link to a video of how this little light works.

And a pic of the switch mounted in the centre console.
And here's the plan for the wiring for the whole system.
So once the radiator came back with the thread in it, I sealed in the switch and decided I had run out of week for fabing the mounting for the fan to the radiator.
So it has gone back in, with the old fan set up
I did however put the radiator and fan in to check I had clearance in all the right places, it was tight and I have to mount it off to one side and high, but it fits.
So once I get a weekend where I can pull it out again, and sort the mounting brackets, I know where it needs to go, which looks like this.
But in the mean time I had a chance to build the loom to go from relay to the fan and thermoswitch.
Here is a pic of the relay mounted, and the loom sitting on top of it, the relay is the one with the inbuilt fuse on top!
So I have hooked up the loom to the fan and bridged the earth for the thermoswitch, AND IT WORKS
So just the final mounting brackets to build, and final fitting and it's a done deal.
Final in this series will be pics of the mounting, so still an update to come
