Voltage inspection
Remove the seat (page 2-2).
Remove the ECM (page 5-73).
Measure the battery voltage using a commercially available digital multimeter.
Voltage (20°C/68°F):
- Fully charged: 13.0-13.2 V
- Under charged:Below 12.3 V
Tool: Digital multimeter — Commercially available.
Battery testing
Always clear the work area of flammable materials such as gasoline, brake fluid, electrolyte, or cloth towels when operating the tester, the heat generated by the tester may cause a fire.
Remove the battery (see above).
Securely connect the tester's positive (+) cable first, then connect the negative (-) cable.
Tool: Battery tester — BM-210-AH or BM-210 (USA, only).
Set the temperature switch to "HIGH" or "LOW" depending on the ambient temperature.
For accurate test results, be sure the tester's cables and clamps are in good working condition and that a secure connection can be made at the battery.
Push in the appropriate test button for 3 seconds and read the condition of the battery on the meter.
For the first check, DO NOT charge the battery before testing: test it in an "as is" condition.
Tester damage can result from overheating when:
- The test button is pushed in for more than 3 seconds.
- The tester is used without being allowed to cool for at least 1 minute when testing more than one battery.
- More than ten consecutive tests are performed without allowing at least a 30-minute cool-down period.
The result of a test on the meter scale is relative to the amp. hour rating of the battery. Any battery reading in the green zone is ok. Batteries should only be charged if they register in the YELLOW or RED zone.
