•Tighten:

Torque - Regulator/rectifier Bolts: 7.8 N·m (0.80 kgf·m, 69 in·lb)

•When installing the bracket, apply a non-permanent lock- ing agent to the bracket mounting screws and tighten them securely.

Regulator/Rectifier Inspection

•With the hand tester set to the R × 1 kΩ range, test the regulator/rectifier according the following table.

If any of the values obtained do not agree with the above table, the regulator/rectifier must be replaced.

Regulator Inspection

○To test the regulator out of circuit, use three 12 V batteries and a test light (12 V 3 ∼ 6 W bulb in a socket with leads).

CAUTION

The test light works as an indicator and also as a current limiter to protect the regulator/rectifier from excessive current. Do not use an ammeter instead of a test light.

•Do the 1st step regulator circuit test.

○Connect the test light and the 12 V battery to the regula- tor/rectifier as shown.

○Check infinity (∼ ) terminals 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.
