CAUTION STATEMENT
As with all electrical equipment, caution is essential when troubleshooting. Remove all watches, rings, and
jewelry before proceeding. Take care when doing power checks. Take time needed to place meter leads
correctly so as not to short to nearby terminals and/or electrical connections. Do not forget to disconnect
power at the battery when doing continuity checks or damage to your test meter may result. All troubleshoot-
ing should be done by a qualified technician experienced in DC voltage and DC testing equipment.
GENERAL STATEMENT
The following guide will present each electrical circuit separately, not including options, unless they are in
electrical series with the standard machine.
1. "Power Off" means key switch is turned off.
2. "Power Disconnect" means battery disconnected from the machine.
