Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below. Problem
The generator volt fault becomes active after a couple of minutes. The generator speed drops from 1800rpm to 1200rpm. The drop in speed is due to the wrong switch setting. The incorrect switch setting gives the wrong signal from the timer relay (TR106) to the soft start solenoid.Solution
Make sure that the switch is set to a three second ON delay function. This setting means that the relay should output current after 3 seconds. Refer to Illustration 1 for the setting of your switch.
