Do you have any type of short circuit protection between the positive lead on the vertical power and the mater contractor? I see the VP lead goes through your firewall (as does mine), if that grommet chafes I believe it would cause a major short. Also to note, I think the earthx batteries have internal short protection but Im not sure if this is what is relied on to protect the main power runs. The manual states it will reset after a cool down period if about three min. I think that would mean if you had a short it would disconnect, then momentarily reconnect every few min?!?

To that point if the battery internally disconnects the only backup option for avionics power would be a secondary backup battery, as a backup critical systems bus would not function.

Any clarity on this would be appreciated and Id love to know what people are doing to protect from shorts on the few connections that go straight to the master contractor.

Thanks!
