Awning 1 $20 BMPRO Repair

[Pdcooper]

As a conclusion to my other post that awning 1 won’t retract on a 2020 Pinnacle 37MDQS; I was successful in restoring full functionality with $20 of parts from Amazon avoiding the need to spend $1000 on an new BMPRO node from the Jayco dealer (until something else fails!) I’d be happy to send the circuit diagram and instructions to anybody that wants it.

I'd like the info "just in case", thanks

Sama here, thanks

I would be be interested as well, I suspect there are tiny relays that need to be replaced

[Textman]

That would be helpful...

I’m working on a further refinements of my external circuit. I’ll post it next week for folks to try at their own risk. Right now awning 1 is extending and retracting normally with one SPDT relay. However a second normally closed needed to lift the ground on the awning 1 ground while operation got awning 2.

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!

It’s 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.

Amazon part numbers for relays and connectors any chance? Thankx.

Install at your own risk. Every failure case may be different and I offer no guarantee other than it is working for me. Failure to cut into supplies that are not already fused, is not advised.
