one slight problem the ignition light and low oil pressure light are permanently on even with ignition switch off and the only way to stop the engine is to pull the coil HT lead off

(dunno if u already sorted)
You wired the lucas coil to the fuse box? i've got the same coil, this issue happened to me when connected the coil to the wrong fuse, went in short circuit.
just wired + to the upper fuse, and it worked fine.

not really had time to play yet

the charge and oil pressure lights do out when the engine is running

it think it's the ignition switch but will have a play

[Bungle]

had a little play

if i remove fuse 9 the lights go out

fuse 9 has a white wire going in and a green wire going out

the green wire feeds the ignition lights

the white wire should go back to the ignition switch

so it's still looking like the ignition switch is not switching and not my c0ck up

i will keep fiddling

But if that is the case then the coil will also have a permanent 12V to it as the ignition switch would not be switching that off either. Stick a multimter on and see - if it is live you'll be getting a flat battery soon and the coil might burn out too.

not with the battery negative not connected

hey bungle
dunno if it can help, but thats where i wired the + lead of my lucas coil:


basically i've just checked for a point that provides live 12v only with the ignition switch turned on.
connected coil there and it worked...
cheers

i think the lack of ignition switching is my problem and not wiring

[GraemeC]

Suppose if you unplug the ignition switch/barrel it will prove it. Even more so if you then stick your multimeter on the wires coming from the switch and check for continuity at the different switch positions.

You have a permanent supply for some reason. The lights go out because of oil pressure and the alternator producing enough zaps to cancel out the zaps going through the iggy bulb. Your indicators ought to also work if it's the iggy switch. Shouldn't be hard to find an ignition dependent supply with a circuit tester.
