With Pyramids, if the P/S gets
overloaded - e.g. short circuit in the cigarette lighter plug, or the screw-on
terminals touching each other when tightened – the supply will shut down its
output for something like 7 minutes after the fault signal is recognized. It
won’t be obvious looking at the mount itself, which appears to still be up &
running. This is a safety factor.
I assume the Mach1 uses Power-Pole connectors, or
else, if the cigarette lighter plug is used, I have had a case where one of the
power leads “inside the plug” had disconnected from its solder/crimp
joint.
Also, check the fuse in the screw-on tip of that kind of
plug – which would also lose power to the mount, even if the Pyramid is
fine.
Check the cable to the mount, and others that the
supply may be feeding, in case something else is overloading it. Best to remove
any other devices, and simply first test the mount operation
alone.
