No-Load Test
- Connect test meters as shown in illustration. Start engine and increase speed to 2300 RPM (gradually). Read the "B" terminal voltage. It should be 13.8-14.8 volts with current draw of not more than 10 Amps. If current is over 10 Amps the battery is discharged or internally shorted.
- If voltage reading is not steady, it indicates regulator points are dirty, or defective connection exists at "F" terminal.
- If voltage reading is too high, it indicates the following problems: Regulator low speed gap is too wide. High speed point gap is too wide. High speed point resistance is too high. Open circuit regulator coil or voltage relay coil. Open circuited regulator coil or voltage relay coil. Open circuited regulator "N" terminal or "B" terminal. Low speed point contact tension too heavy. Loose regulator ground connection.
