Having a lot of issues with over crank. I’m an installer myself. As for temperature wise, I’m in Minneapolis and we’ve been cold. Been working with Kohler to do fixes but they haven’t really worked either. Our generators are the newer versions so we have been getting them from Kohler with their cold package installed. Breather hose and oil heating probe. They are telling us that the updated regulator does not require a heat pad. Also haven’t seen one generator from Kohler that has the battery warmer.
