GRJ,
I got everything working again. The PIC chip in the TAS EOB board originally had a prong bent/folded to prevent it from engaging the PIC base. I had straightened it thinking I may had accidentally bent it. Nope. It’s supposed to be that way. I pulled another PIC chip out of another EOB board and the last prong was folded inwards. I straightened it out and the EOB board is no longer causing a short at the transformer. I also fixed the smoke unit. I replaced the triac and it solved the problem. Thanks for your help!
