INTRODUCTION STE/ICER (SIMPLIFIED TEST EQUIPMENT FOR INTERNAL
COMBUSTION ENGINES-REPROGRAMMABLE) PROCEDURESContinued
When cables are connected, the large key (1) located by the white stripe (2) on the cable connector mates with large keyway
(3) of connector on VTM or transducer.
a. DIAGNOSTIC CNCTR
ASSY CABLE W1.
The W1 is used to power the VTM and provide access to test points and sensors
connected to vehicle/equipment-mounted DCA.
b. TEST PROBE CABLE
The test probe cable for both general and special measurements. It is used for
measuring voltages, frequency, resistance and continuity, and also for the first peak
series and compression unbalance tests. W2 is divided into two color coded leads:
red for E1 and black for E2. Test clips E1 and E2 of W2 attach to points on the
vehicle/equipment being tested.
c. IGNITION ADAPTER
The ignition adapter cable W3 is used in measuring dwell angle, points voltage,
engine rpm and power tests. W3 is divided into two color coded leads: red for E1
and black for E2.
