note | Disconnecting the alternator output wire and connecting the ammeter may not thoroughly diagnose an alternator output line resistance increase problem because of an insufficient connection between terminal "B" and the output wire. |
note | When the alternator output is high and the value displayed on the ammeter does not decrease until 30 A, set the value to 40 A. Read the value displayed on the voltmeter at this time. When the value range is 40 A, the limit is maximum 0.4 V. |
