1.0 SEQUENCE TESTS - (Engine not running)

Preparation & Setup
It is assumed the truck has been programmed using the correct Truck Configuration File and GE
Statex III Enhanced version 1.00 (if truck is equipped with a 17FB144 CPU card) or version 14.00 (if
truck is equipped with a 17FB101 CPU card) or later software prior to proceeding with the following
tests. If not, refer to "Electrical Propulsion Components" for instructions for preparing the Truck Con-
figuration File, programming the truck, and usage of the GE software menu system.
•
Always disconnect 74C at GFR for static testings (engine not running). Failure to do so may
result in damage to battery boost SCR and/or dead batteries.
•
If the truck body has not been installed or the body is raised, place a steel washer on Body Up
Switch or jumper circuit 71F to circuit 71, to simulate body down condition.
•
If hydraulic pressure is low, connect a jumper wire between circuit 73S and 710. (This step will
be necessary if all hydraulic brakes are installed and engine is not running).
CONTROL SYSTEM SELF-TEST
1. Set up PTU as described previously using the communication port in the electrical cabinet.
2. Turn control power switch On.
3. Verify the two digit display shows 00 after a 10 second delay. If only a single digit 8 is displayed,
check for a faulty CPU (FB101 or FB144) card.
4. If the two digit display shows numbers other than 00, refer to "Electrical Propulsion Compo-
nents" for a listing of possible codes, code descriptions, event restrictions, detection information
and possible reasons for the problem. An attempt should be made to correct any obvious prob-
lems before proceeding.
5. If the problem has not been resolved, select the proper section of this procedure (digital, analog
etc.) and use the PTU to aid in troubleshooting the problem.
6. If the entire electrical system is to be checked, the checkout procedures should be performed in
the sequence listed if possible.
