These should be your rectifier values, I believe,check that one of these is your model board

Model TP1 TP2 TP3 TP4 TP5
AS-2518-18 +5.4 +/-.8VDC +230 +/-27.4VDC +11.9 +/- 1.40VDC 7.3 +/-.9VAC +43 +/-5.4VDC
AS-2518-49 +5.4 +/-.8VDC +230 +/-27.4VDC +11.9 +/- 1.40VDC 7.3 +/-.9VAC +43 +/-5.4VDC

Until you get the rectifier working properly there's no point playing with the other stuff. Start at the first link in the chain then work downstream to the SDB.

Quoted from djreddog:

All fixed. Powering up issue was 3 bad pins. Coil locked on was a bad transistor.
Thanks for all the help!

Nice work! Congrats
