Joe,
Well that's definitely progress.
Take out the Track 2 PM and replace it temporarily with one of the others. If Track 2 then works you'll need to send out the old Track 2 PM for service.
However, be careful because if your Track 2 connections are bad, and they somehow killed the old Track 2 PM, they could kill the new one too. Turn up the voltage only a little bit when you fire it up, and check the overload light for a short circuit.
