Hi; I have a 1930, 6 volt positive ground. If I leave the fuse in after shutting off the car, I am experiencing about .2 volt drop in voltage at the battery over about 6 hours. Is that normal?
If not;
Do I need to just start disconnecting wires from the horn, lights etc. to find the drain?

Or, can I check various wires with a clamp amp meter to determine the drain or will all of the wires show an amperage reading if there is a drain?

Thanks for your help.
