malc Run one wire from each of the relay 30 terminal to 12 Batt source both fused.
No need to fuse your wires to the 86 terminal.

Boostedpimp alright so basically this is what I should have correct?

malc I would install 2 40 amp fuses. 1 between each relay and the fan.

Fuses are installed between relay and power source, ie the battery.

Circuit breakers work great! There are 50 amp breakers available. I would also put circuit protection in the switched side as said earlier.

Good luck!

malc If a fusible link blows you have a serious problem to investigate.

If you are out on the road and the if the link should blow out - what are you going to do rewire the system on the road ???

If you replace a blown fuse without finding the cause the only thing you get is a second blown fuse.

carsavvycook A circuit breaker will work just fine. Make sure you install a 15AMP in line fuse in the key on power wire to the relays for additional protection. It will not blow when the fan kick's in and draws more AMPS.

carsavvycook If you are putting the fuse in the constant battery feed wire to both relays and are afraid of it blowing a 40 amp fuse, use a 50 amp fuse. Also make sure this wire is 10 gauge, and I would hook it directly to the battery, to eliminate any other voltage draws.

jaguarxk120 If you use a 40 amp fuse on a fan that draws 40 amps then the fuse is way too small. A fuse is used to protect devices from gross overloads. Using a 40 amp link will work for a time but will open in time as heavy curent folws will degrade the wire. Remember the fuse link is a cheap way around using proper fuses in a circuit. For a 40 amp load I would use a 50 amp fuse, it will protect the wiring if something go's wrong. TF

I was told to use a fuse link because they have a saturation time before blowing where as a fuse lets go as soon as that limit is reached... so lets say the efan spikes to 42 amps once in a while during startup and im using 40 amp fuses.. i'd be popping fuses each time it kicked where as with a 40 amp fuse link it would last through the initial spike because the spike is only a second or two long. Is that correct? that's what I was told previously

Boostedpimp Thanks for the suggestions guys much appreciated

Any thoughts on what size fuse link I should use? Im guessing since the relays and inline fuses are 40 ampers maybe the fuse link should be 40 as well

Currently i've gotten away with using a 40amp inline fuse, 35's blow often so should i throw the 40 somewhere in there?

Thank you for the help guys really appreciate it
