Final Awning 1 repair circuit
For all that asked, the attached circuit is provided Implement at your own risk. Some basic electronic circuit knowledge and a good back while cramped in the basement, are needed!
When Awning 1 on my 2020 Pinnacle 37MDQS failed to retract, it was diagnosed by phone support at BMPRO to be a non-serviceable defective relay inside the BMPRO Node in the basement. Jayco dealer wanted about $1000 for a new Node board. I worked out this external patch for about $30 for two SPDT relays and some connectors off Amazon. The relays are typically used to add extra lights on a car; so are 30Amp capable.
The fault symptom was the top left pin Ch7+ goes to 12 Volts when retract is selected, and not as should be, at 0 Volts. The first external SPDT relay provides the correct polarity reversal to retract awning 1. The second relay closes when operating Awning 2 and interrupts the ground to Relay 1. At first, with just relay 1, Awning 2 operation, in either direction, caused Awning 1 to retract!
Itís a little bit of work to install this patch but at lot simpler than replacing the whole node. And a lot cheaper at $30 versus $1000.
