Section 1 GENERA T OR FUND AMENT ALS MA GNETISM 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.
Section 1 GENERA T OR FUND AMENT ALS A SIMPLE A C GENERA T OR 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 STA- TOR. The ROTOR is a permanent magnet which con- sists of a SOUTH magnetic pole and a NORTH mag- netic pole.
Section 1 GENERA T OR FUND AMENT ALS NOTE: AC output frequency at 3720 rpm will be about 62-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.
Section 1 GENERA T OR FUND AMENT ALS FIELD BOOST When the engine is cranked during startup, the engine control circuit board Terminals 9, 10, and 11 (Wire 14) are energized with 12 VDC.
Section 1 GENERA T OR FUND AMENT ALS Reroute stator lead 44 from the line side terminal of CB1 (renamed as CB1A in Figure 1-9) to the ground stud location previously occupied by stator lead Wire 33. 2. Move smaller gauge (#18 AWG) Wire labeled #44 (not shown), from the top of CB1A to the top of CB1.
Section 2 MAJOR GENERA T OR COMPONENTS RO T OR ASSEMBL Y 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.
Section 2 MAJOR GENERA T OR COMPONENTS 3. Two excitation winding output leads (No. 2 and 6). These leads deliver unregulated excitation current to the voltage regulator.
Section 2 MAJOR GENERA T OR COMPONENTS Figure 2-6. – Excitation Circuit Breaker VOLTAGE REGULATOR: Six (6) leads are connected to the voltage regulator as follows: • Two (2) SENSING leads deliver ACTUAL AC out- put voltage signals to the regulator.

Section 3 INSULA TION RESIST ANCE TESTS EFFECTS OF DIRT AND MOISTURE Moisture and dirt are harmful to the continued good operation of any generator set. If moisture is allowed to remain in contact with the Stator and Rotor windings, some of the moisture will be retained in voids and cracks of the winding insula- tion.
Section 3 INSULA TION RESIST ANCE TESTS DANGER!: DO NOT ATTEMPT TO WORK WITH SOLVENTS IN ANY ENCLOSED AREA. PROVIDE ADEQUATE VENTILATION WHEN WORKING WITH SOLVENTS. WITHOUT ADE- QUATE VENTILATION, FIRE, EXPLOSION OR HEALTH HAZARDS MAY EXIST . WEAR EYE PROTECTION.
Section 3 INSULA TION RESIST ANCE TESTS a. Across Wires No. 33 and 2. b. Across Wires No. 11 (POWER) and 66. c. Across Wires No. 33 and 66. d. Across Wires No. 2 and 66. If a breakdown in the insulation between isolated windings is indicated, clean and dry the Stator.
Section 4 MEASURING ELECTRICITY METERS Devices used to measure electrical properties are called meters. Meters are available that allow one to measure (a) AC voltage, (b) DC voltage, (c) AC fre- quency, and (d) resistance in ohms. The following apply: • To measure AC voltage, use an AC voltmeter.
Section 4 MEASURING ELECTRICITY MEASURING A C FREQUENCY The generator's AC output frequency is proportional to Rotor speed. Generators equipped with a 2-pole Rotor must operate at 3600 rpm to supply a frequen- cy of 60-Hertz. Correct engine and Rotor speed is maintained by an engine speed governor.
Section 4 MEASURING ELECTRICITY ELECTRICAL UNITS AMPERE: The rate of electron flow in a circuit is represented by the AMPERE. The ampere is the number of electrons 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.
Section 5 ENGINE DC CONTROL SYSTEM INTRODUCTION The engine DC control system includes all compo- nents necessary for the operation of the engine. Operation includes off, preheat, cranking/starting, running, shutdown, and fault shutdown. The system is shown schematically.
Section 5 ENGINE DC CONTROL SYSTEM Page 19 CIRCUIT CONDITION- PRE-HEAT: When the PRE-HEAT SWITCH (SW) or the REMOTE PANEL PRE-HEAT SWITCH is closed by the operator, battery voltage is delivered across the closed switch contacts to the PRE-HEAT CONTAC- TOR (PHC) via Wire 150.
Section 5 ENGINE DC CONTROL SYSTEM Page 20 CIRCUIT CONDITION- CRANKING: When the START-STOP-SWITCH (SW1) or REMOTE PANEL START-STOP-SWITCH is held at "START" position, Wire 17 from the Engine Control circuit board is connected to Ground.
Section 5 ENGINE DC CONTROL SYSTEM Page 21 CIRCUIT CONDITION-RUNNING: With the FUEL PUMP (FP) and FUEL SOLENOID (FS) operating the engine should start. The START- STOP SWITCH (SW1) is then released. Engine con- trol circuit board action terminates DC output to the STARTER CONTACTOR (SC), which then de-ener- gizes the (SC) to end cranking.
Section 5 ENGINE DC CONTROL SYSTEM Page 22 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 ground. ENGINE CONTROL circuit board action de- energizes DC output to Terminal 9,10, & 11 (Wire 14).
Section 5 ENGINE DC CONTROL SYSTEM Page 23 CIRCUIT CONDITION- FAULT SHUTDOWNS: The engine has mounted to it a HIGH WATER TEM- PERATURE SWITCH (HWT) and a LOW OIL PRES- SURE SWITCH (LOS). While running, ENGINE CONTROL circuit board action keeps Terminal 12 Wire 85 energized with battery voltage.
Section 5 ENGINE DC CONTROL SYSTEM ENGINE CONTROL CIRCUIT BO ARD GENERAL: The ENGINE CONTROL circuit board is responsible for cranking, startup, running, and shutdown opera- tions. The board interconnects with other components of the DC control system to turn them on and off at the proper times.
Section 5 ENGINE DC CONTROL SYSTEM battery and starter should not exceed 0.12 VDC 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 larg- er the required cable diameter.
Section 5 ENGINE DC CONTROL SYSTEM 14 AMP FUSE This panel-mounted Fuse protects the DC control cir- cuit against overload and possible damage. If the Fuse has melted open due to an overload, neither the priming function nor the cranking function will be available.
Section 5 ENGINE DC CONTROL SYSTEM The positive (+) battery cable (13) attaches to one of the outer posts of the contactor along with Wire 13 for the DC supply to the fuse (F1). The starter cable (16) attaches to the remaining outer post. Attached to the small 2 lugs are Wires 56 and 0.
Section 5 ENGINE DC CONTROL SYSTEM Figure 5-11. – Glow Plug ENGINE PRO TECTIVE DEVICES The engine will shut down automatically in the event of anyone or more of the following occurrences: • Low oil • High engine coolant temperature • Engine overspeed LO W OIL PRESSURE SWITCH The oil pressure switch has normally-closed contacts.

Section 7 DIA GNOSTIC TESTS Page 37 INTRODUCTION The “Diagnostic Tests” in this chapter may be per- formed in conjunction with the “Flow Charts” of Section 6. Test numbers in this chapter correspond to the numbered tests in the “Flow Charts”.
line voltage should read between 242-252 VAC. If voltage and frequency are good, no adjustment is needed. If voltage and frequency are low or high, proceed to next step. 4. Turn the governor adjusting screws to obtain a no-load frequen- cy as close as possible to 62-63 HERTZ.
Section 7 DIA GNOSTIC TESTS Page 39 TEST 4 RESULTS ABCDE FG VOLTAGE RESULTS ABOVE ABOVE BELOW ZERO OR BELOW BELOW ABOVE WIRE 2 & 6 60 VAC 60 VAC 60 VAC RESIDUAL 60 VAC 60 VAC 60 VAC EXCITATION WIN.
3. Set the Start-Stop Switch to “START.” During cranking only, measure DC voltage. It should read 3-5 VDC. Reconnect Wire 4 to the Voltage Regulator. If voltage is measured, it can be assumed that the Field Boost is working. Stop testing. If volt- age is not measured, proceed to Step 4.
Section 7 DIA GNOSTIC TESTS Page 41 TEST 8- CHECK SENSING LEADS / PO WER WINDINGS DISCUSSION: The Voltage Regulator “regulates” excitation current flow to the Rotor by electronically comparing sensing voltage to a pre-set reference voltage. The sensing voltage is delivered to the Voltage Regulator via Wires 11 and 22.
one meter test lead to Wire 1. Connect the other test lead to a clean ground. The meter should read “Continuity”. RESULTS: 1. Repair, reconnect or replace any defective wire(s).
Section 7 DIA GNOSTIC TESTS Page 43 RESULTS: 1. Replace the Rotor if it fails the test. 2. If Rotor checks good, perform “Insulation Resistance Test,” on Page 14. TEST 12 - CHECK MAIN CIRCUIT BREAKER DISCUSSION: The main circuit breaker on the generator panel must be closed or no output to the load will be available.
approximately 0.8 Amps. Apply full load to the generator. The amp reading should increase to approximately 2 Amps. RESULTS: 1. If amperage was measured between 0.8 to 2 Amps in Step 2 and Step 3, the charging system is working. 2. If no amperage was measured, check the VOM fuses and veri- fy the functioning of the Amp Meter.
Section 7 DIA GNOSTIC TESTS Page 45 * Resistance values in ohms at 20° C. (68° F.). Actual readings may vary depending on ambient temperature. A tolerance of plus or minus 5% is allowed. RESULTS: 1. For Steps 2 & 3, keep in mind that the resistance values are very low.
Section 7 DIA GNOSTIC TESTS Page 46 PROCEDURE: 1. Set a VOM to measure DC voltage. 2. Disconnect the connector from the wires of the fuel pump. 3. Place the positive (+) test lead on Wire 14 and the negative (-) test lead to clean ground. Press the pre-heat switch, battery voltage should be measured, if not, disconnect the other end of Wire 14.
3. Set the VOM to measure resistance (“Rx1” scale). Connect one meter test lead to Wire 0, Terminal 2 on the Engine Controller Circuit Board. Connect the other test lead to a clean frame ground. “ Continuity” should be measured. RESULTS: 1. If battery voltage is NOT indicated in Step 1, check continuity of: a .
Section 7 DIA GNOSTIC TESTS RESULTS: 1. If “Continuity” is not measured in Step 2, repair, reconnect or replace Wire 0 (between Start-Stop Switch and ground termi- nal) as necessary. 2. If engine cranks in Step 3 when Wire 17 is grounded, but will not crank when the Switch is set to “START”, replace the Start- Stop Switch.
Section 7 DIA GNOSTIC TESTS b. Open armature (wire broken) will be indicated by low or no RPM and excessive current draw. c. Grounded armature (wire insulation worn and wire touching armature lamination or shaft). Will be indicated by excessive current draw or no RPM.
Section 7 DIA GNOSTIC TESTS Figure 7-16. – Clamp-On Ammeter TACHOMETER: A tachometer is available from your Generac Power Systems source of supply. Order as P/N 042223. The tachometer measures from 800 to 50,000 RPM (see Figure 7-17). Figure 7-17. – Tachometer Figure 7-18.
Section 7 DIA GNOSTIC TESTS TEST 28- CHECK FUEL SUPPL Y DISCUSSION: If the engine cranks but won't start, don't overlook the obvious. The fuel supply may be low. Many RV gen- erator installations "share" the fuel tank with the vehi- cles engine.
Section 7 DIA GNOSTIC TESTS 6. Place test leads on each end of wire, continuity should be measured. 7. If continuity is measured, test battery voltage on Wire 14 going to circuit board on Pin 10, with prime switch pressed. Meter should read battery voltage.
Section 7 DIA GNOSTIC TESTS TEST 35- CHECK V AL VE ADJUSTMENT DISCUSSION: If the engine is having a hard start, no start, or rough running condition, then the valves will need to be checked for proper clearance. If a unit has a lot of hours on it, the valves will need to be readjusted.
Section 7 DIA GNOSTIC TESTS 8. Crank engine again and see if fuel is coming out of the fuel lines. RESULTS: 1. If no fuel is noted in Steps 3 or 8, replace fuel injector pump. (Reinstallation of all original shims will be required.) 2. If fuel is noted, proceed to next step in flowchart.
Section 7 DIA GNOSTIC TESTS NOTE: For units out of warranty, refer to Quicksilver Diagnostic & Service Manual - Diesel, P/N 082034 for further engine service information. This manual can be found at www.guardiangener- ators.com, under “Brochures,Manual & Specs - Recreational Vehicle - Manuals”.
