Step 1 |
|
|
|
|
|
|
|
|
L |
||
1) Check accessories which use excessive amounts of electricity. |
|
||||
Are accessories being installed? |
|
M |
|
||
|
|
|
|
||
|
|
|
|
|
|
YES |
|
A |
|
|
|
Remove accessories. |
|
|
|
||
NO |
Go to tep 2. |
|
|
|
|
Step 2 |
S |
|
|
|
|
1) Check the battery for current leaks. ( 9-9) |
|
|
|||
Is the battery for current leaks OK? |
|
|
|
||
|
|
|
|
|
|
YES |
Go to Step 3. |
|
|
|
|
|
|
|
|
||
NO |
• Short circuit of wire harness |
|
|
||
• Faulty electrical equipment |
|
|
|||
|
|
|
|||
|
|
|
|
|
|
Step 3
1)Measure the regulated voltage between the battery terminals. ( 9-10) Is the regulated voltage OK?
YES |
• |
Faulty battery |
|
• |
Abnormal driving condition |
||
|
|||
|
|
||
NO |
Go to Step 4. |
||
Step 4
1)Measure the resistance of the generator coil. ( 9-10) Is the resistance of generator coil OK?
YES |
Go to Step 5. |
||
NO |
• |
Faulty generator coil |
|
• |
Disconnected lead wires |
||
|
|||
|
|
|
|

Step 5
1)Measure the generator no-load performance. ( 9-11) Is the generator no-load performance OK?
YES |
Go to Step 6. |
|
|
NO |
Faulty generator |
|
|
Step 6
1)Inspect the regulator/rectifier. ( 9-11) Is the regulator/rectifier OK?
YES
NO
Step 7
1)Inspect wirings. Is the wirings OK?
YES |

|
|
• Remove the front seat. ( A8-7) |
|

|
|
|
|

|
S |
|
|
|
|
|
|
• Turn the ignition switch to the OFF position. |
|
|
|
|
|
|
|
• Disconnect the battery - lead wire. |
|
|
|
|
|
|
|
• Measure the current between - battery terminal and the - |
|
|
|
||||
battery lead wire using the multi-circuit tester. If the reading |
|
|
|
||||
exceeds the specified value, leakage is evident. |

*In case of a large current leak, turn the tester to high range first to avoid tester damage.
*Do not turn the ignition switch to the “ON” position when measuring current.
