3000m Electric fan wiring

[laikathedog]

Hi,

I have removed my single original three wire electric fan and fitted a pair of 7.5" spal pull fans.

I have three wires to the original fan, one is earth and two others both enter the fan body, in looking at the wiring diagram I think that i can take one of this pair to each of my radiator fans ( replicating the US layout) and run my own earths and the otter will trigger both fans at the same time ?

let me know if that is a working solution

thanks

Personally I would use a relay with a direct fused feed from either the battery or your main live feed to the relay and then to the fans plus a direct earth from the chassis to the fans. Then use the otter switch to trigger the relay this way your not putting any stress on the the otter switch and it should be more reliable.

Suggest also adding a manual "override" switch for those days the otter decides to be unreliable............

I did away with the otter switch. (Stopped it leaking by not being there!)

I use a kenlowe sensor to relays to 8' fans.

I do use and would recommend use relays. Direct power without routing through anything else.
