Single wire lighting coil connections

#1
On an engine with a small 3 amp lighting coil with a single wire... How would it be wired to a light?

Would I just run the wire to the + on the light and ground the - to the engine block?

I am refering to a Honda GX with the single wire.

Thanks,

Yes you can wire a light that way. No rectifier or regulator needed. If you want a light switch, install it in the + wire between engine and light.
