The cold start advance solenoid is located on the
bottom, outboard side of the injection pump.
There is a single terminal input lead to the wax
motor.
1. Install JT07158 (FKM10429A) TIME TRAC Kit .
2. Disconnect wiring connector from the cold start switch
to wax motor harness. Verify that there is a voltage
potential (12 or 24 volts, depending on application) at
the wax motor connector.
3. Start cold engine and run at 1200 rpm. Check and
record injection pump timing.
4. Connect a jumper wire across the wax motor connector
terminals. After approximately 30 seconds, check
injection pump timing.
There should be a 7--10 decrease in timing indicating
proper operation of the cold start advance system.
If no decrease in timing was noted, have the injection
pump serviced/repaired by an authorized ADS Diesel
Repair Station.
