TESTING NEGATIVE TRIGGER DOORLOCKS
•
Some models with power locks use a negative (-) triggered door lock system.
To find the door lock wire with your multi-meter:
1. Set to DC voltage
2. Attach the (-) probe to chassis ground
3. Probe the wire you suspect of being the door lock wire
4. When the switch is at rest, the meter should read 12V
5. Lock the door with the switch. The meter should read 0V or close to it. If it does, that is the correct wire.
