I've been on the road before and had a generator that wouldn't come on line so I had them shut down the engine then I hit the reset button a few times... they fired back up and were good to go. Well this recently happened again and I said that they needed to shut down the engine completely (not just pull breakers and cannon plugs) for it to completely reset. They didn't do the shutdown, they pulled the breakers and cannon plug and pressing the reset button did not work - still had codes. I agree that pulling the plug would take away power but I think you have to start from a shutdown engine for the reset to work properly.
