'soft reboot' on a dual battery vehicle

[Norman Horse]

Hi All

I'd like to try a 'soft reboot' on my 607.

I've been reading in various places about the '3 minute rule' and all the steps for battery disconnection and reconnection.

But am I correct in thinking I also need to remove and replace the 50A maxi fuse for the rear battery, simultaneous to disconnecting and reconnecting the main battery?

And if this is the case - is there a preferred order of disconnection? Disconnect main battery and then remove 50A maxi fuse? Or remove the fuse first?
And when reconnecting - put the fuse back in first? Or re-connect the main battery first..?

Thanks in advance for your help !
