Rectifier Test
! WARNING
Disconnect battery leads from battery before testing
rectifier.
NOTE: Rectifier can be tested without removing from en-
gine.
1. Disconnect all wires from terminals on rectifier.
2. Use an ohmmeter (R x 1000 scale) and perform the fol-
lowing test. Refer to drawing for rectifier terminal iden-
tification.
NOTE: Due to differences in the manufacture of ohm me-
ters, the internal battery polarity may vary from manufac-
turer to manufacturer. As a result, the test readings may be
a direct reversal of those listed. If so, reverse meter leads
and reperform test.
