New electric fan blowing fuses.....Help?
I just installed a new electric fan. I had to hard wire it straight to the battery.
Here is how I have it wired, From the battery, I have a 12 gauge wire going into the cab to a 30amp togle switch. Then from the togle switch, it goes back into the engine compartment to an in line 20 amp fuse. From there it goes to a 40amp relay, then to the fan. all with 12 gauge wire. My problem is that it keeps blowing the 20amp fuse. The fan will run great while it is idleing. But, if I take it for a drive, come back 20 min later the fuse is blown. I went up to the parts store to get a couple of extra fuses, and they tell me that a 20amp fuse is not enough for an electric fan. Is this correct? They rcomended at least a 30amp. I stepped it up to a 25amp. I am kinda scared to go any bigger on the fuse. I don't want to burn up anything. Anyone have any idea's? Everything is new(fan,togle,relay, etc...). Nick |

If you have the relay wired properly, you could run a 2 amp fuse. The fuse that actually powers the fan from the battery should be a 30 amp though. At work, we use inline fuseable links on fan circuits becouse of the slow burn they have instead of the instant pop of a fuse.

I am running a pair of 14" flex a lites, with a Painless wiring relay/ thermostat kit. the kit runs a 30 amp circuit breaker instead of fuses. my fans are said to pull 14 amps ea, & i did run the setup on a pair of 20 amp fuses , & toggle(no relay) for a while. I didnt seem to have any problems with fuses tho.... what fan(s) are you running?

If you want to add a pusher, as an auxilary fan, you may get a little extra cooling on the hot days.....bear in mind that the pusher is only about 80% efficent, as compaired to a puller fan. my thoughts are add 2 PULLERS, & ditch the stock fan
