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.
