My Stars machine was working pretty good i would say. Until my chimes stopped working. Turns out I had a bad chime coil and i guess it cause the fuse to blow. Meanwhile i decided to clean up my connectors replaced all of the female ends and cleaned the male ends. Now when i turn the machine on the MPU LED doesnt turn on at all. Not sure what to do from here. Any help would be appreciated still learning to read the schematics as it is extremely confusing to me.

Quoted from jburas7:

Most likely because you Rect board isn't working correctly. Did you check the fuses there with a Multimeter? Pinwiki has a good right up on the rect boards and to tackle them step by step.
Sorry I can;t link it from work but shouldn;t be too hard to find.

thelaw Thanks so much for sending me to that! it helped me solve this problem. When I put my wires back into the J4 connector i accidentally put pin 12 in the pin 11 hole. Moved it over and it came right on. Now the only problem i am having is that when i use the left flipper the left drop targets reset. But only sometimes (not every single time i hit the flipper). Also whe i start a game the drop targets reset like 3 time when they use to only do it once when starting a game.

Update: Had some time to play a game. Looks like the drop targets are resetting every time i hit any switch. Any ideas?

put it into switch test, look for stuck switches, test all switches .....
