This generator is capable of producing 27.5 amps at 120 volts.

It is essentially two 1650 watt 120 volt gens in one unit. Presently they are connected in series yielding either 14 amps at 240 volts or two separate 120 volt circuits at 14 amps each.

There are 4 wires coming from the windings, each one is 14 amps at 120 volts. If they can be separated and connected in parallel, the result would be 27.5 amps at 120 volts.

Most gens have all 4 wires coming from the stator, some splice two in the stator and bring out only 3. In order for this to work, all 4 wires need to be present.

If so, it's fairly easy to reconnect them in parallel.

/\ This

lot of the older Generac's used to be wired like this. There was a switch you would flip for either 120 or 120/240. In the 120 position you had full capacity as it would parallel the windings.
