Charging System. Regulator Circuit Test-1st Step:

Regulator Circuit Test-1st Step:

• Connect the test light and the 12V battery to the regula­tor/rectifier as shown.

• Check Y1, Y2, and Y3 terminal respectively.

• If the test light turns on, the regulator/rectifier is defective. Replace it.

• If the test light does not turn on, continue the test.

Regulator Circuit Test-2nd Step:

• Connect the test light and the 12V battery in the same manner as specified in the "Regulator Circuit Test-1st Step".

• Apply 12 V to the BR (voltage monitoring) terminal.

• Check Y1, Y2, and Y3 terminal respectively.

• If the test light turns on, the regulator/rectifier is defective. Replace it.

• If the test light does not turn on, continue the test.

Regulator Circuit Test-3rd Step:

• Connect the test light and the 12 V battery in the same manner as specified in the "Regulator Circuit Test-1st Step".

• Momentarily apply 24 V to the BR terminal by adding a 12 V battery.

Check Y1, Y2, and Y3 terminals respectively.
