I have a spare PCB board if you are interested. It is used and was working when I removed it from our failed Onan generator (engine failure).
We are currently in the Bahamas and will be for about another 4-6 days. There is a FedEx office here so I should be able to ship it to you in Panama.
Email me at pstas2003 at yahoo dot com if interested.
All the Best,
