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
at all.
The outside fuse is good.
I took off top cover and I don't see and internal fuse.
Is there a diode I should be looking for?
I'm sure it has to have some kind of protection if the wires are
reversed.
Any help would be great.

i am no expert but check the output transistors
short circuit will probably take them out
good luck and let me know how you make out

Thanks, It turned out to be the SCR, I disconnected it
and now it goes to 13.8 volts.
So I ordered a SCR from astron.

I have had problems with the scr circuit. I just cut it out most of the time.
