You should be using the ‘fixed’ AC or DC power supply terminals on your power pack depending on the type of switch machine your are using. The terminals should be clearly labeled on your power supply as to what they are.

If you ARE using the proper terminals, it could be a hidden short circuit where two wires are in contact that shouldn’t be. Sometimes the easiest thing to do is just to strip out the wiring in question and start over again.

The other possibility is that the switch machines themselves have a burnt out coil, the result of the examples I gave above. If you can, remove the switch machines and, using short wires, hook them up to the power pack and switch machine control as shown on their instruction sheet. If they operate correctly in this fashion, then you may have crossed wires out on your layout somewhere. If they still operate incorrectly connected in this manner, then the machines are probably no good and will have to be replaced.
