HELP Astron 70 amp PS
I have a astron 70 amp power supply and was hooking up a transmitter
to it and I pulled the power supply closer to me and the positive wire
came loose and hit the ground terminal on power supply.
Now when I turn it on you can hear the power supply turn on and the
light on the power swithch comes on, but no volts comes up on the
meter. I checked the terminals on the back and no volt, very little if


Check to see if any or all of the pass transistors are shorted. If so the
crowbar may be kicking in and keeping the output voltage low. Doubt this is
the case as the fuse would probably blow. Otherwise check the 723 voltage
regulator IC and see if it is putting out any voltage. YOu may just have to
change it out as that seems to be a weak point of the supplies.
