Manual override; fans

[bigcheez2k3]

Back to topic, ffs, i'll change it now.

I've got a 3 pin plug, i've just noticed. now i tested the live to the fans etc, it all seems "ok", but the fans do not kick in. one of them is dead, i've just tried manually switching them on, and one works, no the one that works i'm trying to wire up.

As said, i can't just lobb a live and earth on the fan with a switch, as it starts burning the wire up <---- how do i overcome this?

That's already been explained, you use a relay to take the higher power.

This thread has answered my question anyway, as my fans currently don't work either and been considering wiring them up to something.

12v -- relay --- fan ?

I think that's the jist of it, with the switch wired into the relay to power it on.

With an earth too.
