Over Voltage with New Battery Disconnect Switch
So it would look like this. (Starter cable could be on either side, whatever the rules say, drawn here assuming a switch that could handle 100 + amps)
When running, everything is the same. Once battery gets recharged all current flows to ignition and field.
When the kill switch is closed, alternator output takes the quickest path to ground. Ignition and field are left without power.
Engine dies because the ignition has no power.
The alternator stops producing any more power because the field demagnatizes and the engine is no longer turning.
It would need a switch with a grounded terminal.
