Strange Electrical Problem

[Robert/Texas]

I’m experiencing a problem starting the engine in my ’28 roadster. This problem occurs about every three or four times that I go to start it.

When I turn on the ignition switch the ammeter shows no discharge and when I step on the starter nothing happens. The horn and lights work though. I’ve been able to solve this problem by putting the transmission in third gear and pushing the car a few feet forward and the car starts like it normally does.

All thoughts and suggestions will be greatly appreciated.

Thanks, Robert
