8 Troubleshooting
The following section will provide a guideline when troubleshooting
problems. While this guide should help determine the majority of
problems, it is not a complete check. If you can not determine the cause of
your problem, contact your dealer or Norac for assistance.
NOTE:
Some of the procedures described in this section will require the use of
a multimeter. If you do not own one your local machinery dealership
should be able to lend you one.
Table 6 can be used to single out which part of the controller is
malfunctioning given certain symptoms.
