Battery Disconnect Switch

[Bob Bidonde]

I am not technically convinced that the battery cutoff switch should be in the grounded battery cable. My Model A's have alternators and solid state devices. Both have 12V negative ground electrical systems with their cutoff switch in the positive battery cable that runs to the starter. For many years I have run these cars this way without any electrical issues with alternator regulators and solid state devices.

I doubt there is a technical argument that supports putting the switch in the grounded cable is a better way than putting the switch in the cable to the starter, so I will maintain my status quo which has been successful. I am not saying putting the switch in the grounded cable is wrong.



Thanks to all who responded to my question.
