What about a parallel harness like they do with the Honda generators?
The only consumer gens which are designed to be paralleled are inverter types which A Honda 2000i is.
The gen the OP is dealing with is an old school non inverter gen.
This gen is designed to be able to supply 240V and 120V, The full wattage only available via the 240V connection..
The 120V connections only give you half the wattage.
This is due to the gen having a winding which is 240V and there is a center tap. The 120V is derived due to the center tap.
The problem the OP is having is they want ALL the wattage on one 120V output.
The only way to do this is to separate the windings of the gen head at the center tap.
Only then can the two 120V windings can be paralleled.
The problem is that the way the AVR is wired may be causing an issue since the AVR is sampling a small voltage from one of the windings..
This can be done in most cases but it is not easy or for the faint of heart.
