'86 Jimmy 4in Lift, 40’s, tons, 8.1 Swap- 700r4 said PNNNNN

This is not a dedicated trail rig, but does trailer to the destination usually. I am currently in the planning phase of doing a 52/56" spring swap, and getting back to being more road worthy.
What's the setup? Fuses, relays, one or two fans? Need more info....
 
One 50? Lol

You should have a relay for each fan with a separate fuse feeding each relay.

You should have a relay for each fan with a separate fuse feeding each relay.

So the only benefit to having one fuse for each fan is so that if one shorts or the individual relay can't deal with the power draw of both fans turning on at once you won't start melting things. Obviously two relays means you could control both fans but that's not of much importance. If one fan shorted you'd likely have a problem anyway but at least you may spare the wires and relay. My current setup is one relay with one fuse. It works well as its designated for the pull of two fans. 50 amp fuse is welding lol!
 
I run one fan more often than two and I wanted redundancy. You're already running the wire so what's another relay and switch?

I run both fans. I just like it that way but I also don't run them all the time. There going off a temp of course. Soon to be controlled by the efi system.

I don't see it buying anything of importance to change it. If it wants to light up and blow a fuse then that's an easy fix. If the relay goes out for some unlikely reason then you hardwire it. I think I had it previously powered by the windshield wipers...I think. Anyways that had a fuse as well.

I'd like to be able to over ride the fans so when I go into a river it's not slinging it everywhere like last time.
 
Mine are switched from a bmw dual temp switch and I have overrides on my dash.

I know the new efi thingy will control it for me and I know I want an override. I wonder if there's a timed switch... like you hit it and then you have a few minutes until it pops back on so I don't forget lol.

Sorry for hijack greg.
 
Wire in a buzzer so when it's switched off it buzzes

Good idea!

Slightly off topic off topic story...I used to work around this guy who was continually shit faced and he put a buzzer on thw lathe so when his cut finished he would come to. He was a beauty. Same guy bent some round tube in a lathe and it picked up a 55 gallon trash can and threw it up in the air then hit again and flew across the machine shop. It was like a bicycle kick. He was totally unphased by it.
 
I usually don't run fans in the winter. Enough airflow from not having wheel wells keeps it around the 170* mark. I will be running them both on 1 90amp relay. What size fuse would you recommend? 40 amp?
