Thanks Dan!

i could not have done it without your books and parts to study ;-)

Happily, just two IGBTs were ALL that was damaged:

The new beefier PC board was completely undamaged this time!!  So the "use 
the IGBT as a fuse" thing is finally working!!

I did replace the two TVSs directly in front of the IGBTs since they caught 
significant "impact" damage as the lids were coming off.  I spaced them off 
the board this time so they were "in the way".  They got 
"flattened"!!  Goodness knows how much force is going down in there!!  So 
$15.56 worth of new parts and she is all good to go again :-))

Time to start work on the strike rail :o))

Cheers,

        Terry
