Troubleshooting - Check Relay Operation
Verify Relay Contact Closure
Using a digital multimeter/VOM, check to ensure relay #2 has a contact closure (short) when activated.
If there is a contact closure on relay #2, but that short is not detected on the P12 connector, there is a problem with the wiring circuit or P12 connector.
If there is no contact closure on relay #2, but the associated LED is lit, there is a problem with the relay board. Replacement relay boards are available in our parts shop.
