[RE-wrenches] Kohler 12RES at 120vac full power

[Kirk Herander, VSE]

Hey All,
I have a customer who just replaced their old standby Kohler 8.5 RMY (20 years old) with 12RES. The 8.5 was stator-lead wired for 120vac @ full power. for the sake of the inverters input. Remember those days? 

I'm looking at the RES service manual, and there is no description of having this option(the old manual had a wiring diagram of stator and breaker config for 120v). The digital controller can be programmed for 120vac, but obviously the stator leads need to be reconnected from the factory setup of 120/240. This was a simple thing on the older models via terminal strip.

Is this field rewiring still a OK thing to do from a warranty perspective? AND I have not looked inside at the access of the wiring on a terminal strip yet. Some genny person installed it without knowing the old genny's wiring at 120v. Thanks fellow old timers.
