It came on but suddenly I saw a large quantity of smoke and smelled ozone. WTF I said and went running for the extinguisher. Seeing no flame I waited for the smoke to clear. Apparently lacking a ground strap, the glow plug system picked the shortest route to ground, which apparently was the metal sheath on the EGR probe.

Just a word of caution, when you unhook that battery to do work on the car, leave it unhooked until you are done, no matter how much you want to enjoy in hearing about the misery and tribulations of other car owners....
