    66 B/B Engine stalls and Lights go out simultaneously

    66 B/B Engine stalls and Lights go out simultaneously. Eventually it will start and run but this has happened several times. Could this be a ground problem? Any suggestions would be greatly appreciated.
    Thanks,
    Bob

    Bob,
    Have you checked the bulkhead connector on the firewall? Very common area for issues like you are having. Corrosion build up can and will cause problems after 53 years.

      Bob, when checking for connection problems I would have the car running and then wiggle the harness connections, that way you'll have a idea of the area of the problem. along with Leif's suggestion try looking at ignition switch harness.

        Also check the battery terminal connections. I used to leave the negative cable a bit loose so I could twist it off by hand (a poor man's quick disconnect). One time the car wouldn't start because it was just a bit too loose.

          I had a similar problem a few years back, might be an issue with the negative ground cable connection to the frame.

            Under the Brake Master Cylinder there are two bulk connectors. The engine side connector has a heavy Red wire on the top inboard corner. Take the connector and lightly wire brush the brass clips. Reconnect and retry your starting.
            This happened to my 1966 last week.
