Follow the instructions for the leak- down tester you are using to determine the likely problem area s. Run engine for 5 minutes allowing engine to reach operating temperature. Page 32 Conclusion: Cylinder 1 is weaker cylinder. The Digital Multimeter , Fig. The Digital Multimeter can be used to read volts, ohms, The V-Twin flywheels have a ring of magnets 1 on amperes, and to test diodes. NOTE: Before testing alternator output, use an accurate tachometer to temporarily adjust the engine speed to the RPM specified in the test instructions.

Test alternator output. The DC alternator provides DC current for charging a 12 volt battery. Use resin core solder when 1. If the 2. Page 40 The battery is not used for the lights, so lights are available even if the battery is disconnected or removed. Current for the lights is available when the engine is running.

The output varies with engine RPM, so the brightness of the lights changes with engine speed. The regulator-rectifier converts the AC current to DC and regulates current to the battery. The charging rate will vary with engine RPM and 1. Temporarily disconnect stator wire harness from regulator-rectifier. Page 20 Amp Regulated Alternator 7. If NO or LOW output is found, be sure that 20 Amp Regulated Alternator regulator-rectifier is grounded properly and all The 20 amp regulated alternator system provides AC connections are clean and secure.

If there is still current through output leads output, Page 45 4. Press the reset button to restore power. Page 47 4. Test for continuity between the inverter case and the GFCI ground. Page Anti-Afterfire Solenoid If the previous tests have not revealed a faulty 6. Press button on test box and note AC voltage.

If the alternator output is within specification Volts. Batteries contain ACID which is poisonous and causes severe burns. Avoid contact with skin, eyes or clothing. Page 50 Installation b. Fill battery cells with distilled water after charging for batteries that have been in 1.

Before installing battery, connect all equipment service. See typical wiring diagram, Fig. Make sure key switch is OFF before connecting The engine wiring harness consists of a ground wire jumper wire. Page 52 3. Turn key switch to ON position. Meter should display battery voltage. If meter does not display battery voltage, replace engine wiring harness. If meter displays battery voltage, test the solenoid. Set meter to test for continuity.

Remove pressure switch. Connect one tester lead to the switch terminal and the other lead to the metal body of the switch, Fig. Sticking pinion gear due to dirt. Conditions Affecting Starter Motor Performance b. Damaged pinion or ring gear. Bound or seized starter motor bearings. Starter clutch slipping. Battery faulty or damaged. Page Solenoid Test 6. Attach one meter test lead to each stud terminal on solenoid 2, 3 , Fig. Page Governor Test Governor Test Static Check To determine whether a governor problem is being caused by the actuator or the control module, Dynamic Check perform the following static check exactly in order shown.

Perform dynamic check exactly in order shown. A pair of jumper wires and a known good 12 volt 1. Page 61 2. Remove air cleaner assembly. Torque four 8mm screws to in. Disconnect governor link at carburetor. Torque two 6mm screws to 70 in. Remove governor control bracket with actuator. Remove plastic shipping plugs. Adjust the primary regulator output to 11 Less than 11 inches of water inches of water pressure.

Refuel the tank. Fuel supply shut off. Open fuel tank. Check for proper operation of all fuel lock-off safety devices.
