Thanks, Bumper, may tackle that this winter. Problem so far is I have not been able to identify what you would think of as a traditional power buss.
Thanks

If you have an "avionics master switch", the switch that turns off power to all the toys, then the point to put the isolation diode is in series with the wire coming from the battery to that switch (i.e. when you turn the switch on or off, there is still power constant on one terminal - that's the one coming from the battery :c). The the new battery will wire to that terminal of the switch.

If there's no master switch and a bunch of fuses or circuit breakers, and you are blessed with turning off each instrument separately, then you'll need to locate the wire that provides power to those fuses (there may be a common wire going from one fuse to the next to provide power to each) that wire would be serving as the "buss". You'll need to locate the end that comes from the battery and insert the diode in series with that wire at the "first" fuse.
