I thought that the constantly manned spaces within machinery spaces were positive pressure to stay clear of smoke/fumes and that principle was for safety beyond war fighting capability.
Not much to argue with there, and because the engineering spaces in ships tend to be (but are not always so in practice in the civilian world) sealed off from living spaces, you can blow a ton of air in there and not fumigate the living spaces.

BTW, for the old Navy salts here, from 1996 to 2012 when I was regularly riding gas turbine powered warships as a Navy contractor, I began to see unmanned main propulsion spaces except during general quarters. Aft steering is never manned except at GQ, much different than in my day when it was always manned (see McCain collision).

Swap your starboard relay to the port side and test on ignition. If it functions it is simply your relay and if not, tone out your hot at relay and work your way towards the blower if you have 12v up to that point. suerte

I would have but couldn't find the relay, so toning it out led me to the relay, changed it all is good

Excellent! Yeah, I glossed over your initial post... On the upside, now that you have identified those relays you can figure out and label the others from your schematic for the future. Glad you got er worked out.
