General Information - Toro Z Master 7500-D Series Service Manual

General Information

1. Always use a digital multi-meter for electrical testing procedures and record voltage reading results.
2. Before performing any electrical troubleshooting, always:
-Verify proper battery voltage (above 12.4 volts): Batteries reading 12.4 volts or less are considered discharged
-Check that all engine and chassis ground wires are securely connected and not damaged.
3. Use of test lights and continuity testers may result in false readings and lead to an incorrect diagnosis.
4. Occasionally, electrical testing requires the use of a jumper wire to bypass a safety interlock switch, allowing
the technician to continue troubleshooting by taking the switch out of the circuit.
NOTE: Jumper wires should be used for troubleshooting only, NEVER leave a jumper wire in place to
bypass a safety circuit.
