In my Cessna 172 the master solenoid isolated everything. Really, everything. Including the starter solenoid. The only thing not isolated by the master solenoid was one lonely fuse feeding the master switch contact that fed only the master solenoid coil.
That way when the master was off, there was no battery connection to anything but the master switch contacts the control the solenoid coil. The other half of the master switch disconnected the only other current source, the generator.
