= IDLE CONTROL TRANSFORMER OUTPUT
The printed circuit board is supplied with AC voltage from Wires 11S and 44S, this voltage /frequency signal is
used by the printed circuit board for governor control operation.
When the Idle Control Switch (SW2) is activated to the “ON” position Wire 83 from the printed circuit board will be
connected to Wire 0 frame ground. There are two Idle Control Transformers (ICT) that sense current flow off the
main power windings. The voltage signal from the ICT’s connect to the Printed Circuit Board via Wires TR1/TR2
and are used for sensing load on the generator. With no-load on the generator there is no current supplied from
the ICT’s and the engine will run at a lower RPM. When a load is applied to the generator the ICT’s supply a
voltage signal to the Printed Circuit Board and the engine RPM will be increased to running RPM approximately
3600RPM.
