I guess the subject says it all..

To the point,,,

I'm picking I have a dead regulator and it's killed the pgm's power valve
circuit..

To me it looks like a fried transistor in the PGM. I don't know how to attach and image
to his posting....

wish i did....

If you look at the pgm with the white and black plugs facing away from you on the
left side below the black plug there are 4 transistors in a line.

the transistor on on the end of the this group of 4 seems to be heat damaged...

Are these parts used to drive the power valve servo ?


I have fixed PGM's before with dead capacitors but not a power valve
problem.....

I think I will be able to get the transistor part number off the part once
i dig it out of the potting mix...

Also any know the source of a new regulator ??..

Best regards
