My 77 RS ran great on a trip to Toronto yesterday charging all the way at 14+ volts. Parked it for a hour, then no start. just a loud click and volt meter goes to 0.
Checked the battery connections: OK
Tried to boost it with a car, same results: click.
Bump started it to get home, shut it off, still no start?
It charged OK all the way home 60 miles.
Relay or starter?
