Now, as many of you will deduce from this post I’m not an electrical genius. But I’d like to get an answer to this one as it’s stumping me

1929 Sport Coupe
Points ignition
12v Negative Earth with alternator
Kill switch in the battery to chassis line (edit negative post thanks Paul)
1 x engine to chassis earth
1 x gearbox to chassis earth
All kill switch on voltage is correct
Charging fine

Kill switch off and main fuse in and pressing horn switch I get around 6 volts at the horn.

Same process but with the main fuse out the voltage is 0.2 volts i.e. negligible.

Can I assume that perhaps the voltage is being held by something such as the condenser or even the alternator (Wild guesses

)

The reason I’d like the car to be “totally dead” is that it’s in my house garage.

Any thoughts are welcome and be gentle with me please
