Thanks to all who have chimed in on this thread for the help to get this addressed. I was able to use some recommended DeOxit coating on the newly restripped wires and hook up the wires to the new bus last night with positive results. I have tightened all connections to the hot, neutral, and ground bus connections as well.
Special thanks to the kind folks at WFCO (converter mfgr) who provided me an extra phenolic board to exactly match the old phenolic material that had burned.
I plan to recharge my 12V battery over the weekend and monitor all connnections and behavior. I learned a lot in working on this with everyone's help.
Thank you again!
