Just saw this and can help you out, but first, can you mark you relay pins in your schematic so I can see and know exactly which is 30, 85, 86, and 87 or 87A?
My guess, but want to verify, is:
Left = 30
Right = 87
Bottom and Top are 85 and 86.

Also what is the exact relay you are planning on using? Should be more of a solenoid or 60A panel mount style vs an automotive one.
Hey Air Male.
Thanks for the offer to help but I actually went in a different, simpler direction.

You want to use Schotkky diodes chosen for a low forward voltage drop at peak current (target .5 volts or less). In this application, the diode will dissipate significant power and will need some form of heat sink. You need to be concerned with forward current, voltage and power dissipated when selecting the device.
Aeroelectric Connection does make a single Schottkey diode for this purpose which takes into concern how to mount and connect to it: http://www.aeroelectric.com/Catalog/...M9001-700A.pdf
In your application, I think you need a second diode between the relay and the essential bus. They make dual Schotkky diode packages, but it would be up to you to connect and heat sink it. Example (TO-220 package): https://www.mouser.com/ds/2/389/stps40m60c-956723.pdf
What is the simpler direction you've chosen?
