RE: 2015 Tiara 50 Coupe

My trim tabs stopped working this weekend (Lenco Eletric Tabs).  My mechanic checked all relays and connections.  Everything tested good. It seems as if the FIREBOY fire suppresion system must be energized before the trim tabs will work????  The FIREBOY system is not energizing at all.  I contacted customer service for a wiring diagram.  Has anyone ever come across this issue???

Feedback is appreciated. The boat tilts about 45 degrees at cruise....NOT FUN!

If both systems are not energizing did your electrician verify power and ground on that particular circuit?
I would bypass the fire system and wire the tabs directly to another breaker/ circuit. I don't know why they would tie them together in the first place unless they ran out of room on the panel.
