Electrical Tests: Notes
- With battery in normal operating condition and solenoid adjusted properly, connect positive lead of voltmeter to buss bar on relay assembly. Connect negative lead to ground.
- With no load, voltage should be approximately 12.5 volts. When locks are operated, voltage should be 11 volts. If no voltage is read at relay, test circuit breaker as follows.
- Connect positive voltmeter lead to light green terminal of circuit breaker, and negative lead to ground. If reading of 12.5 volts is not obtained, connect positive lead to battery side of circuit breaker.
- If 12.5 volts are now obtained, the circuit breaker is defective and should be replaced. If 12.5 volts are not obtained, check for broken feed wire or loose connection.

- To check for faulty solenoids, disconnect the solenoid connectors one at a time, while operating the door lock switch. If none of the solenoids work, the problem may be a shorted solenoid or faulty relay.
- If defective solenoid is found, disconnecting it will allow the remaining solenoids to operate, provided the relay is not damaged.
