HELP Astron 70 amp PS
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. Rich |
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.
