Briggs 10kw LP control board failure from new

I purchased a new B&S 10kw LP with 200 amp ATS, and did a self install in 2009. It would only run for 9 seconds and quit, so B&S sent a local authorized service technician to examine the situation.  My letter to that technician in 2025 below explains it all.  I would appreciate your comments on the frequency of this kind of problem with control board failure and self-install dip switch setting errors too.  I am awaiting a new BSPP 311353GS control board (an updated board to replace the 204006 which is due in 10 days. Here is my most recent kind letter to that technician:
_________________
 
     In 2009 you came to my B&S 10kw generator (customer self-install bought online from Home Depot) to inspect it under warranty for not running and sending 240v to my 200 amp B&S ATS (Automatic Transfer Switch), your visit resulted in a battery explosion in my home utility room.

     Did you submit a report of the warranty visit (to be reimbursed for your time) and the battery explosion to Briggs and Stratton or file and/or report internally at Richard Electric of what took place? It would run for 9 seconds and then die.  The unit was left unused for all these years.  

     During my forensic study of the problem now in July 2025, I discovered that the di[p switches on the ATS control board were set to 0 watts, i.e. DPSW1 set to 0-on, and DPSW2 set to 00-on.  Pages 9 and 10 of the original Installation & operator's Manual (No. 209506GS 3/6/2009) describe how to set them.  The barcode on that manual is 0-24847-71955-0

     I also found that while the engine starts and runs fine, it quits at 9 seconds running time repeatedly.  Upon testing the 570cc VanGuard V-Twin engine, it was being starved of fuel, and I found that the 12v+ was not being supplied from the control board BSPP 204006 to the LP solenoid coil terminal (blue wire).  When I applied an independent 12v+ to the coil, the engine would run continuously, and I ran it for nearly 2 hours. However it would not send 240vac to the ATS, which may be explained by the ATS DPSW1 and DPSW2 dip switches being set to 0 watts.

     I have not received a quotation from you to date following your technician visiting the site on 7-17-25 to see if the wiring was satisfactory for the 13kw LP Briggs & Stratton install. He confirmed the wires were #6 AWG copper.
