Really screwed this up. I will try to go in order of what happened. I was trying to find a good supply for 12V on my rotten dog power supply board. I was getting a strange test from a connector labeled 12V, I unplugged it and saw that the pin from the board was cut, and thats why the DMM was not reading 12V correctly.
Now I know what I did next was super wrong, with the power on I tried to plug the connector back in, but it is not keyed properly so I shifted everything over on the connector one spot to the left. Big Buzz, smelled like smoke, turned machine off real fast. I plugged the connector back in correctly and turned the machine on and the displays were all dead. I turned back off, and checked the fuses and one was totally blown. I replaced it turned machine back on and now MORE sizzle and spark! Turned machine off again and very afraid to turn it on.
Really bummed, have no idea what to do now, very afraid to turn machine on. Please help. First pic is the connector I plugged in wrong. Second pic on the far right is the fuse I replaced. I do not have schematics for the rotten dog power supply BTW.
