Lift the two AC leads off the bridge rectifier and measure with

ohmmeter the resistance between these

two

leads should measure 0.14 Ohm. No continuity should exist between these two leads and the ground.

Bridge Rectifier

Normal

voltage running

the rectifier (while the engine is operating at 1800 rpm) is measured across

the

two

connections on the bridge rectifier.

(See

the illustration below.)

Testing the Bridge Rectifier

Set

your Ohmmeter's scale on

RX1

( +

and

set the

needle

zero.

Connect

the

(+)

positive

lead

from

the

Ohmmeter

point #4. Taking the Ohmmeter's

negative

(-)

lead, momentarily touch points #1,

#2, #3, and #5. The Ohmmeter

should register

no deflection for any of the points touched.

Remove the positive

(+)

lead from point

and connect the negative

(-)

lead to point #4.

Touch points #1, #2, and #3. The

needle

should deflect, indicating a passage of current
