Reply to "Overheating Bridge Rectifier on TAS SAW Board"

I really appreciate the input.  I did a freewheeling bench test.   With 18 volts from the transformer,  the engine seems to be drawing about 3.8 ma ( if I am reading this correctly).  Rectifier gets really hot.Johnacton, the pictures are helpful.  The bottom one with the BR on the topside is the one that I have.I am guessing that I did the upgrade about 10 years ago, so it may be an older board as you suggest. The engine is a two can motor SD 45, originally PS 1.

Like everyone else,  all my more recent TMCC upgrades are ERR.  I may use this one as a learning experience to see if I can replace the triacs.  One more question, is there a way to test the "diode in the bridge"? And just for clarification is the diode integral to the bridge or upstream/downstream in the circuit.  Thanks for all the help.
