What went wrong? Had to short right?

x2.

I have used 3M clear packaging tape for this kind of thing. Just stack up 3-4 layers, hole punch and scissor cut it to the shape you need. Stick it onto the MCPCB.

OP while you’re at it, you should also de-bur the back side of the reflector dish… if it does have a sharp edge. Just trim down the sharp edge with a knife.

Alrighty. Springs should be arriving Monday and I’ll see what I can do to get this thing going. Got jb weld to insulate as someone suggested earlier any objections to jb weld?
