Thanks for the info. I dare say you found the likely problem. I do have mysetup so that the battery is always connected to the glow driver, even when charging. I have probably gotten by to date because I limit the charge rate, but NOT to trickle. Must have been a spike this time that burned a connection and caused a short, which lead to the fire.

Well, I know the fix now.

I really appreciate you looking through the old posts. Most helpful.

Cheers!
