INTRODUCTION
ABOUT THIS BOOK
This book was written to assist the authorized service representative (ASR) or technician in
troubleshooting the Series 9800Q. This manual contains:
•
a functional description of each part
•
wiring connections
•
illustrations of the circuit boards and their indicators, connectors, jumpers, and switches
•
diagnostic test procedures
•
a troubleshooting (Problems) section.
USING THE TROUBLESHOOTING SECTION
The Troubleshooting section lists common problems, probable causes, and corrective action to
be taken. The probable causes and checks for each problem are presented in logical sequence,
allowing you to rule out one set of symptoms before going on to the next. Thus, following the
procedures as listed should help isolate your problem.
A double line at the end of a problem sequence indicates the last of the checks for that problem.
If your 9800Q still is not working, recheck your symptoms and follow another problem sequence if
necessary. If you encounter problems you cannot solve by using this manual, call GASBOY
customer service at 1-800-444-5529.
Checks and corrective actions requiring voltage measurements assume familiarity with and are
done with a voltmeter unless noted that an oscilloscope or ohmmeter should be used.
