Troubleshooting

CAUTION

Remove all jewelry, especially rings and watches, before doing any electrical trouble- shooting or testing. Disconnect the battery cables unless the test requires battery voltage.

For effective troubleshooting and repairs, you must have a good understanding of the electrical circuits and components used on this machine (see Wiring Sche- matics section of this chapter).

If the machine has any interlock switches by–passed, they must be reconnected for proper troubleshooting and safety.
