90-826148R2 MARCH 1997 ELECTRICAL - 2A-25
Capacitor Discharge Module (P/N 827509) Ohms Test
a - Spark Plug Wire IMPORTANT: Spark Plug Wires Are Screwed into CDM.
b - Part Number: 827509
Date Code:0415 (Julian Date and Year: 5=1995)
c - Pins are Labeled: A:Black - Ground
B:Black/Yellow - Stop Circuit
C:White - Trigger
D:Green - Stator
d - Capacitor Discharge Module P/N 827509
e - Test Harness P/N 91-825207A2
A resistance check, although not necessary for any troubleshooting procedure, can be made of the CDM as fol-
lows:
NOTE: This test can be performed using the test harness (p/n 84-825207A2). Do Not connect the test harness
plug to the stator/trigger engine wire harness.

NOTE: Due to the differences in test meters battery polarity, results other than specified may be obtained. In such
a case, reverse meter leads and re-test. If test results then read as specified on all tests CDM is O.K.. The diode
measurements above will be opposite if using a Fluke equivalent multimeter.
