Cooling fan wiring
Hi all,
should the cooling fan be wired into the constant live or the switched live circuit?
Cheers Chris

I've got mine permanent live but not relayed, is this necessarily a bad thing?

mine is permanent live, no temp switch, just runs all the time. you only need a relay if your temp sensor is wimpy.

as the motor takes a fair bit of current and thermoswitches are not bullet proof might as well put a relay in the circuit,costs nowt anyway and could
save your engine

...and makes it easier to wire an 'override' switch into the sysetm if so desired too.
Dont just build it.....make it!

This means it would still be running when parked up.You must have one very heavy duty battery on your car!

The above link suggests it only runs with ignition on. Means you cant walk away from your car when it's hot and the fan should be on. But
i'd be very worried if my car stalled at traffic lights anyway. Plus if the fan was drawing too much current that you couldn't start the
car! Potentially very dangerous.
So i'm with Conrod with this one, but just make sure your car is up to starting when the fan is on!
