      Yes, 7.3 volts is low, but under what circumstances was that measured?
      Key ON, bike not running?
      Bike running?
      Lights ON or OFF?

      While you measured that 7.3 volts, what was the battery voltage under the same circumstances?

      We need a few more details.

        Disconnect the r/r and see if it will fire up on just a fully charged battery.
