15.Measure the resistance of the exciter winding. ENGINE SIDE 6-PIN CONNECTOR On the engine side of the 6-pin connector, test between the black/blue wire and green wire. Specification: 0.2 ~ 0.3 Document your results and continue. If the exciter winding measures a little over the specification, it may not need to be replaced.

1. INVERTER TYPE GENERATOR..11-1 3. ECO-THROTTLE 2. FULL TRANSISTOR IGNITION ..11-2 (ELECTRICAL GOVERNOR) ....11-3 1. INVERTER TYPE GENERATOR CONSTRUCTION The Inverter generator has an outer and an inner rotating set of magnets for both the generator and the ignition. The inner set of magnets generate AC in the stator windings, while the outer set generates AC for the ignition coil.
Page 101
2. FULL TRANSISTOR IGNITION Operating Principles The positive (+) and negative (-) power sources are provided from the exciter winding. AC current is provided to the Ignition coil from the negative (-) power source. Current switching to the ignition coil is controlled by the Field Effect Transistor (FET). The FET turns on when the pulse pole front end reaches the ignition pulse generator and starts to amplify the current in the ignition coil primary winding.

3. ECO-THROTTLE (ELECTRICAL GOVERNOR) Operating Principles • Variable Engine Speed The inverter’s CPU compares the current output voltage, current and engine speed with what is programed it its memory and sets the throttle position accordingly. The actual required engine speed then is based on generator load ratio and temperature.
