Best aux fan?

[FLG]

Idk Wtf j wrote there... Lol yes it's on high speed when you press the snow flake. And I used a small nut and bolt to join the wires and then insulated it. My friend needed the resistor

Meant to say "without it, causes it to be on high speed when I hit the snowflake button"

In which case you are overloading the low speed circuit. Keep a large fire extinguisher within reach and be will to spend a bunch of money to repair the damage (if you catch the fire in time).

A fuse is sized to protect the wires, not the load. If you increase the size of the fuse the wires are then unprotected.

Yes but according to the etm both wires are the same gauge. I've ran it like this for over a year now on super hot track days without issue

I've traced both the high and low circuit in early and late cars and honestly the only difference between the high and low circuits is the resistor which, if overloaded shorts open and removes the load.

I think the 15a fuse is strictly based on electrical engineering fundamentals that says the fuse should be rated to the design load regardless of what the circuit can handle.... which happens to be 30a.

thanks so much for that helpful insight jakass619.

So, I put a 20a fuse in slot 3 last night, and it blew. The aux fan is fairly new in past 6 or 9 months. The only other electrical change I have made is installing George Graves' dimmer. How should I start to track down the actual issue?
