Kawasaki WORKHORSE 250 (2003) [279/322] Rectifier circuit inspection

ELECTRICAL SYSTEM 16-23

Charging System

Regulator/Rectifier Inspection

•

Remove:

Regulator Bracket Bolts [A]

Connector [B] (disconnect)

Regulator/Rectifier [C]

Rectifier Circuit Check:

•

Check conductivity of the following pair of terminals.

Rectifier Circuit Inspection

W-Y1, W-Y2, W-Y3

Tester connection

BK/Y-Y1, BK/Y-Y2, BK/Y-Y3

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 must be replaced.

NOTE

○

The actual meter reading varies with the meter and the

individual rectifier. Generally speaking the lower read-

ing should be from zero to one half of the scale.

Regulator Circuit Check:

To test the regulator out of circuit, use three 12 V batteries

and a test light (12 V 3 ∼ 6Wbulbinasocketwithleads).

CAUTION

The test light works as an indicator and also a cur-

rent limiter to protect the regulator/rectifier from ex-

cessive current. Do not use an ammeter instead of

a test light.

•

Check to be sure the rectifier circuit is correct before con-

tinuing.

Regulator Circuit Test-1st Step:

•

Connect the test light and a 12 V battery to the regula-

tor/rectifier as shown.

•

Check Y1, Y2, and Y3 terminal respectively.

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

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