I believe there is a micro-switch that allows the AGS to start providing the generator slide is completely in the retracted position, it is called the "Safety Lock" on the Silver Leaf. It is visible from the passenger side of the generator slide when it is fully extended. Unfortunately the slide tends to move slightly out after a period of storage time. When that switch is not pressed it prevents the AGS from starting. This is a safety feature designed to protect anyone working in or around the genset when it is in the open position.
So, to assure this will not restrict the starting on the AGS, unplug the one wire connector connected to the switch and wrap it safely away from any components. The generator will now start if the AGS is activated even if the generator slide is not fully positioned in the retract mode.
Hopefully, that works on yours and is a help.
