Don't know that your GT lounge is the same as ours, but...
For ours I believe that the lounge motor is always (live) - it is not controlled by the 12V
battery cutoff. I think it goes through a thermal breaker that is phyisically to the rear of the circuit breaker panel. This puts them inside the messy electrical compartment that is beneath the lounge seat. These thermal breakers are presumably individually replaceable - but I don't know anything about them. What makes this design interesting (ie stupid) is that you need to be able to recline the lounge a bit to reach the nuts holding the seat cushion onto the the lounge track in order to get to the fuse that needs to be replaced in order to recline the lounge a bit.
