Fan over ride switch

[markwast]

Has any one a wiring diagram to fir a over ride switch for the cooling fan, Im crap at electrics so like to be safe rather than sorry.

If it's a standard system then the simplest way is to graft a new wire onto the fan earth
and run that to a switch, the other terminal from the switch goes to earth.

Think lanciamad has done this in his hpe....

You should def use a relay, if not, too much current is going through the switch

[thecolonel]

Agreed, relay is always the best option.

Get a standard 4 pin relay

30 to earth
87 to fan earth wire
85 to + 12v
86 to switch
switch to earth

Relay is deffinately the way to go, if you buy one in packaging they more than likely tell you which wires connect to the relay anyway. Just to clarify, mine's not currently an over-ride switch, but an additional switch for the secondary fan i've got fitted.

If it helps, I could compile and publish Andy Batchelor's redesigned electrics trialled and fitted to his Betas.  This rerouted the high-current circuits for lighting (fan too with dash override) away from the main fusebox, with an array of relays in a secondary fusebox in the position where Lancia fitted its own secondary fuxebox in the Automatic Betas.

Contact Darren Cooksey (Montecarlo Consortium Member Sec) before Gaydon and get him to bring the comprehensive wiring diagram he has for this including a light to tell you the fans are operating.
