Customer Question

I have a KOHLER Power System 135 standby generator. When it starts, engine accelerates to correct RPM and runs fine. All gauges operate as designed however, after about 15 minuets with or without load the electrical gauges start to fluctuate for no obvious reason. Frequency and voltage gauges go back and forth at the same time suggesting common problem with electrical output. Auxiliary fault light also comes on when this condition occurs. It lasts for a second or two then gauges go back to normal then it happens again after several seconds. This cycle repeats itself indefinitely. What do you think is the problem?
