Above the genset is a circuit box leading to conduit going

Customer Question

Above the genset is a circuit box leading to conduit going toward the rear of the coach, I measured 1.5 v AC from the red lead and 1.49 V AC from the black lead. Following the conduit I found the ESCO 50 Transfer switch, the upper relay was from shore
power, the lower relay from the generator. I measured voltage here and again confirmed 1.5 V AC red lead at junction L4 and 1.49 at L6. Genset just not putting out voltage, brushes? control board?
