Battery/Charging System Troubleshooting - Honda MUV700 big red Service Manual

BATIERY/CHARGING SYSTEM
TROUBLESHOOTING
BATTERY IS DAMAGED OR WEAK
1. Banery Test
Remove the battery (page 21-6).
Check the battery condition using the recommended battery tester.
RECOMMENDED BATTERY TESTER: Micro 404XL (U.S.A. only)
Is the baHery in good condition?
YES - GO TO STEP 2.
No - Faulty battery
2. Current Leakage Test
Install the battery (page 21-6),
Check the battery current leakage test (Leak test: page 21-7).
Is the current leakage below
1
mA l
YES - GO TO STEP 4.
NO - GO TO STEP 3.
3. Current leakage Test With
Regulator/ Rectifier
Connector Disconnected
Disconnect the regulator/rectifier connector and recheck the battery current leakage.
Is the current leakage below 1 mA 7
YES - Faulty regulator/rectifier
NO - . Shorted wire harness
• Faulty ignition switch
4. Alternator Charging Coil Inspection
Check the alternator charging coil (page 21-8).
Is the alternator charging coif resistance within 0.1 - 1.0n (20CCI68"'F)?
YES - GO TO STEP 5.
NO - Faulty charging coil
5. Charging Voltage Inspection
Measure and record the battery voltage using a digital multi meter (pa ge 21-6).
Start the engine.
Measure the charging voltage (page 21-7).
Compare the measurements to the results of the following calculation.
STANDARD: Measured BV
<
Measured CV
<
15.5 V
• BV
=
Battery voltage
• CV
=
Charging voltage
Is the measured charging voltage within the standard voltage?
YES _ . Intermittent failure
• Loose or poor contacts of related terminal
NO - GO TO STEP 6.
6. Regulator/ Rectifier System Inspection
Perform the regulator/rectifier wire harness inspection (page 21-8).
Are the measurements correct?
YES - Faulty regulator/rectifier
NO _ . Open circuit in related wire
• Loose or poor contacts of related terminal
• Shorted wire harness
