Does the fan switch require a relay or can it be wired directly to the fan??
If it can be directly wired to the fan, does the bypass switch require a relay??
--Chris
It was discussed in depth not long ago.. basically put a Relay to be safe, especially if your fitting a bypass switch
Thanks Ben; will do.

I'm great with the spanner, but US with the wires can anyone send me a wiring diagram for a electric with or without an overide switch -
Pleease
does this help

or try this if you arent sure the fan switch(thermo) can take switching the power.
by making all the switches switched earths, if there is a short at the switch, or something rubs through the fan wiring, it will power the fan rather
than burning out the loom. probably, i think

Nice drawing Indykid... obvious Autodesk user
pen, paper, camera.
did'nt even scan it.
sod this techy malarkey

Are thermo switches output on/off (digital) or are they like senders for water temp guage and give an variable resistance output (analogue).
If the latter, then a relay is necissery, the fan won't operate properly and will most likely ruin the electric motor. Electric fan motors, like
most motor are designed to work at constant speed with an un restricted input.
thanks for the diagrams guys roblem solved - Awesome!
just had a thought, does the diagram given mean that all the power used byt he fan goes through the thermo switch?? is the thermo switch OK to take this much power or current?
