Fusebox Setup.

[Mando]

Im seting up my fusebox on a hinged panel for easy access and was wondering how many relays the guys with finished cars have installed in their cars? Is it better to run more than less?

Regards.

Mando....It largely depends on two things.

The circuit your switching and the quality of your switches.

Relays are primarilly used for high load applications....Radiator fan, headlights (depends on switch), wipers, fuel pumps, horn etc.. Especially anything which has a motor involved.

In some applications ( ie. my vintage heater/demister) the switches provided are of a heavy duty nature and rated well above the draw of the blower motor so I am not using a relay for it.

However, If I was using a puny little lucas switch to turn the blower on then I would definitely use a relay.

Hope this helps

Les makes a good point, but just to answer your question, I have seven in my electrical.
2 for fans
1 for AUX
1 for Ignition
1 for horns
1 for fuel pump
1 as a spare.

The fan relays are under the hood and the rest are under the dash.

Perry, my setup is similar to yours.

Thanks again.
