ok to start from the beginning a few weeks ago I was hand balling the game to show my little ones how things work. after the ball hits the left slingshot I hear a loud pop from the back box? I immediately power down the game an after inspection I find a transistor physically blown apart? replace the transistor and try to fire the game up no action from the slings? So I immediately check the fuses. I find the fuse for the solenoids to be blown and also to be the wrong value!!!! So I then look for the source of the overcurrent. Sure enough the left coil is showing 0 ohms so bingo (should have checked it right away when I blew the transistor) So after waiting for my parts to arrive I swap out the coil and the diode (just reused the old diode) replaced the fuse with the correct value (2.5sb) and now the moment I power the game on the coil slams shut and If I let it continue will obviously blow the fuse. I checked both switches to make sure they weren't stuck closed and they are good. Did a complete visual inspection of the rest of the area with no evidence of an issue. I am really stumped here? I did forget to check and make sure my diode was ok before I reused it could that cause this issue if it has failed? Any help would be appreciated. Thanks.

well the wires are in the right spot Im sure of that. Diode orientation is correct im sure of. The coil omhs out at a little above 4ohms so that should be fine. What is the best way to test the transistor? it is a brand new TP102 so I hope it is ok? I've never had any luck testing those diodes while they are soldered to the coils is this normal?

ok sounds good. I will start with that thanks a ton LTG I appreciate the help. Kinda wondering if that over rated fuse didn't zap my new transistor.

Ok so I removed one of the legs of the diode and it is good. the coil also tests good. I am going to remove the board today and pull the Q75 transistor to test it and again replace it. at this point im thinking it has to be the transistor right?

I am thinking that it got burned out when the over rated fuse didn't blow. Lesson learned for me anytime I get a new game I'm going to check the fuse values before I do anything.

You guys are rock stars!!!!! I looked up how to check that transistor and with it mounted on the board it was showing .5ohms while everything else around it was showing 47ish ohms. swapped out the transistor and bam she is back up and running!!!! thanks a ton guys. Lesson learned on not checking fuse values when you buy a used game. Thanks again guys this game is my favorite one I'm so glad to have it back!!!!
