No Load Test

  1. Connect a suitable test meter (09081-00010 alternator tester for models with special connector from regulator, or a common regulator tester) as shown in illustrations. Start engine and increase speed gradually to 2000-2300 RPM. Read "B" terminal voltage. Voltage should be 13.5-14.8 with a current draw of pot more than 10 amps. If current is over specifications, battery is discharged or internally shorted.
  2. If voltage is not steady, dirty regulator points or defective connection at "F" terminal may be the cause.
  3. If voltage reading is too high, one of the following problems may be indicated: Regulator low speed gap too wide. High speed point gap too wide. High speed point gap resistance too high. Open circuit regulator coil or voltage relay coil. Open circuit regulator "N" terminal or "B" terminal. Low speed point contact tension too heavy. Loose regulator ground connection.
