Hello, my name is ***** ***** I am going to assist you with this. Since Kohler does not use numerical designators in fault codes, only letters, I am assuming your fault code is actually HB. HB means that the battery that the genset is connected to is reading over 16VDC.This may be due to what ever charging system you have connected to that battery or battery system, be it solar, inverter or float charger. Find out why your battery is being charged to 16VDC.Once you have the battery voltage dropped back to below 16VDC, the code should clear itself.
