Regulator/rectifier inspection
Rectifier circuit check
Remove the regulator/rectifier (see Regulator/Rectifier Removal).
Check conductivity of the following pair of terminals.
Rectifier circuit inspection
Tester connection | R-W1, | R-W2, | R-W3 |
BK-W1, | BK-W2, | BK-W3 |

★ The resistance should be low in one direction and more than ten times as much in the other direction. If any two leads are low or high in both directions, the rectifier is defective and the regulator/rectifier must be replaced.
Note. The actual meter reading varies with the meter used and the individual rectifier, but, generally speaking the lower reading should be from zero to one half the scale.
Regulator circuit check
To test the regulator out of circuit, use three 12V 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 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 regulator/rectifier as shown.
Check W1, W2 and W3 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.

Do the 2nd step regulator circuit test.
Connect the test light and the 12 V battery in the same manner as specified in the "1st step regulator circuit test".
Apply 12 V to the BR terminal.
Check W1, W2 and W3 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.

Do the 3rd step regulator circuit test.
Connect the test light and the 12 V battery in the same manner as specified in the "1st step regulator circuit test".
Momentarily apply 24 V to the BR terminal by adding a 12 V battery.
Check W1, W2, and W3 terminals respectively.

Caution! Do not apply more than 24 V to the regulator/rectifier and do not leave the 24 V applied for more than a few seconds, or the unit will be damaged.
★ If the test light did not light when the 24 V was applied momentarily to the BR terminal, the regulator/rectifier is defective. Replace it. .
★ If the regulator/rectifier passes all of the tests described, it may still be defective. If the charging system still does not work properly after checking all of the components and the battery, test the regulator/rectifier by replacing it with a known good unit.
