advice on wiring diagram before I start wiring
Please could you take a look at the circuit diagram for my race car? I think it is correct but would welcome any comments or advice on doing it in a
different way.

BTW, this circuitlab is a fab site for doing circuit diagrams and is free to use!
thanks, Keith

I wouldnt use an led in the alternator circuit, (unless its specifically designed for it)
I dont know what R1 is for, but it appears to be straight across the battery
and being picky, the alternator dosnt have an earth indicated
but looks good

Good point about the alternator earth. The kill switch opens pole 1 when the main contact closes, so R1 is only there to provide a load to earth in
the event the kill switch is used to stop the engine and the alternator is generating for a few seconds.
I will probably use regular dashboard type bulbs throughout, the circuit lab software doesn't have a component to represent a filament bulb!

the only thing I have seen...
and it may just be me,
but I wouldnt run the live through the brake light switch..
I would run a permanent live to brake light and earth through the switch.
I also do the same with reverse lights
not sure the switches are designed to switch 12v but may be wrong.

Switching earth side still requires 12volt thro switch, an extra run of cable also needed, no point at all, switch power as and when required, works
for all other cars

I must be missing something. Why does switching the earth require a live to the switch
Live to the lamp and earth to the switch. Is that not the way ford did it on the sierra.

I agree, there is bound to be a voltage drop across the brake light bulbs, so there wouldn't be 12V at the point which switches to earth. At
least my (woefully bad memory of) circuit theory tells me that is the case....
