I think I fried my Voltage regulator in my steps. How can I Troubleshoot it?
As soon as I connected my newly assembled STEPS the voltage output plummeted.

TP1 + TP2 = 37.8 VAC
TP5 + TP5 = 52.1 VDC
TP4 + TP5 = .195 VDC

Any Suggestions? I'm headed to Radio Shack to pick up another regulator, or 10

Thanks all!!!

Connected the steps to what?
Before you go pulling the regulator make sure there is not a problem with the device you connected the PSU to.
How is the steps connected to the "what"?
Did you hard wire them together or use some type of a jack/plug thing?

Yea, I geuss that would help ea?

The Steps is connected to my new PPA Via 3 Prong XLR. I've managed to get the STEPS back to 24VDC. I must have fried the regulator. I've made sure there are no bridges and that the ppa is clean from Flux. I'm going to connect them again and see what happens (pocket full of 317's)

<--- Says "good luck".
Let's hope it was that easy huh?

If the output voltage goes down when you connect it to a capacitive load like a PPA and then back up when you unplug it, the regulator is not fried, it is just having trouble coping with the load. You see this most often with LDOs, which frequently have very specific limits on how much load capacitance they will tolerate.
