Page 5: Generator Fundamentals
MAgNETISM Magnetism can be used to produce electricity and electricity can be used to produce magnetism. Much about magnetism cannot be explained by our present knowledge. However, there are certain pat- terns of behavior that are known. Application of these behavior patterns has led to the development of gen- erators, motors and numerous other devices that uti- lize magnetism to produce and use electrical energy. -
Page 6: A Simple Ac Generator
Section 1 GENERATOR FUNDAMENTALS A SIMPLE AC gENERATOR Figure 1-4 shows a very simple AC Generator. The generator consists of a rotating magnetic field called a ROTOR and a stationary coil of wire called a STATOR. The ROTOR is a permanent magnet which consists of a SOUTH magnetic pole and a NORTH magnetic pole. - Page 7 NOTE: AC output frequency at 3720 rpm will be about 60 Hertz. The “No-Load” is set slightly high to prevent excessive rpm, frequency and voltage droop under heavy electrical loading. Generator operation may be described briefly as fol- lows: 1. Some “residual” magnetism is normally present in the Rotor and is sufficient to induce approximately 7 to 12 volts AC Into the STATOR’s AC power windings.

Page 8: Field Boost
Section 1 GENERATOR FUNDAMENTALS FIELd BOOST When the engine is cranked during startup, the starter contactor is energized closed. Battery voltage is then delivered to the starter motor and the engine cranks. During cranking, battery voltage flows through a resis- tor and a field boost diode in the Printed Circuit Board, then to the Rotor via brushes and slip rings. - Page 9 Figure 1-8. – Connection for 120 Volts Only RECONNECTION FOR DUAL VOLTAGE OUTPUT: When connected for dual voltage output, Stator output leads 11 and 44 form two “hot” leads (T1 – Red, and T3 – Black). The junction of leads 22 and 33 form the “Neutral”...

Page 10: Major Generator Components
Section 2 MAJOR GENERATOR COMPONENTS ROTOR ASSEMBLY The Rotor is sometimes called the “revolving field”, since it provides the magnetic field that induces a voltage into the stationary Stator windings. Slip rings on the Rotor shaft allow excitation current from the voltage regulator to be delivered to the Rotor wind- ings. -

Page 12: Crankcase Breather
Section 2 MAJOR GENERATOR COMPONENTS NOTE: If, for any reason, sensing voltage to the regulator is lost, the regulator will shut down and excitation output to the Rotor will be lost. The AC output voltage will then drop to a value that is commensurate with Rotor residual magnetism (about 7-12 VAC). -

Page 18: Measuring Current
Section 4 MEASURING ELECTRICITY Correct engine and Rotor speed is maintained by a stepper motor governor. For models rated 60 Hertz, the governor is generally set to maintain a no-load fre- quency of about 60 Hertz with a corresponding output voltage of about 124 volts AC line-to-neutral. -

ELECTRICAL UNITS AMPERE: The rate of electron flow in a circuit is represented by the AMPERE. The ampere is the number of elec- trons flowing past a given point at a given time. One AMPERE is equal to just slightly more than six thou- sand million billion electrons per second. -

PCB action will then deliver battery voltage to a STARTER CONTACTOR RELAY (SCR) via Wire 56, and to an auto- matic CHOkE SOLENOID (CS) via Wire 14.
- Page 22 Section 5 ENGINE DC CONTROL SYSTEM CIRCUIT CONDITION – RUNNING: With the FUEL PUMP (FP) and FUEL SOLENOID (FS) operating and ignition occurring, the engine should start, and the START- STOP SWITCH (SW1) is released. This voltage is delivered to the PCB via Wire 18A to prevent STARTER MOTOR engagement above a certain rpm.
- Page 23 CIRCUIT CONDITION – SHUTDOWN: Setting the START-STOP SWITCH (SW1) or the REMOTE PANEL START-STOP SWITCH to its “STOP” position connects the Wire 18 circuit to frame ground. Printed Circuit Board action then closes the circuit to Wire 18A, grounding the ignition magneto. PCB action de-energizes DC output to j1 plug to the FUEL PUMP (FP), FUEL SOLENOID (FS) and CHOkE HEATER (CH) are de-energized by the loss of DC to Wire 14.

cold weather starting, voltage drop between the bat- tery and starter should not exceed 0.12 volt per 100 amperes of cranking current. Select the battery cables based on total cable length and prevailing ambient temperature. Generally, the longer the cable and the colder the weather, the larger the required cable diameter. -

Page 53: Check Fuel Supply
TEST 25 – CHECk FUEL SUPPLY DISCUSSION (GASOLINE MODELS): If the engine cranks but won’t start, don’t overlook the obvious. The fuel supply may be low. Many RV gener- ator installations “share” the fuel tank with the vehicle engine. When such is the case, the Installer may have used a generator fuel pickup tube that is shorter than the vehicle engine’s pickup tube. -

The lower the pressure at the venturi throat, the greater the dia- phragm movement, and the greater the movement of the regulator valve. The more the regulator valve opens, the greater the gas flow that is proportional to airflow through the generator. -
