RE: (ET) Re:MY "NEW IDEA" EGT ON FIRE

Yours is still there.  I have seen ones where the wood had FALLEN OUT, and 
that had TALL POSTS.  Even if you fused every interconnect, you could 
still short one battery.  I think what would probably save you is the post 
would melt and break the connection fairly fast.

Yes, KEEP THE WOOD THERE!

How could that happen?  The bottom of my seat is wood.
