I just got this Sharpshooter pin not to long ago and I need to confirm a few things before I move on into more debugging. First is there suppose to be one or two relays? I have seen conflicting pictures on the net were some games have one and some have two. Also are they both the same value if there is two or are they different? My next question is about the power supply it looks like the connector burned and broke off. I think I figured out how to rewire it just want to make sure before I put a fresh molex on it. The bottom pin is blank then 2 blue wires then another blank spot is that correct? Any help on that would be appreciated.

Good news is the CPU is blinking I'm guessing 3 it blinks really fast then keeps repeating the blinking sequence of 3 is that normal? I know it needs like 6 blinks and the board is good I'm just concerned that it keeps repeating the cycle of blinks over and over without stopping.

So is the power supply compatible? Or is that a major problem? Anyone have a PDF of the Power supply schematics for a Sharpshooter 2?

When I looked they give the exact same schematics for Sharpshooter 2 as Sharpshooter. So either someone got lazy or there both the same.

Actually I got the PCB to boot with 6 flashes and it goes to game. All I did was take the PCB out to check one of the blue marked chips and tested it in my chip tester which tested good. Then Socked it and put it back in the game just to retest and it booted. I think all the edge connectors are bad so I have all new .100" connectors and pins on order. I already have a huge bag of .100" headers and the Displays also seem to work but the scoring is all screwed up. It will play some tunes when you hit some switches and I believe a tune when you hit start. But when the game is turned on its still an auditory mess. I'm going to repin the entire game then see what works and what doesn't. Have to test the coils and see if any are shorted next.

As long as the power supply is the same then I guess I'm good I just wish there was a Sharpshooter 2 schematic up and not a clone of the Sharpshooter schematic on IPDB.

Not Sure about the Solenoids as of yet haven't had the time to even sit down the last few days lol. I believe that broken connector was for playfield light bulb power.

My guess is that it's some sort of MPU issue it uses that same midway PCB as a lot of other pinball games. The guy I originally got it from got the game to boot using a baby Pacman PCB. Where did you find that blown fuse at?

Honestly I have no idea.

I have spent last night and the morning/early afternoon today with the sound board. So far I almost have it working 100%. I found out that the SN76477N was bad in the circuit that controls all the main sounds. The chimes was the first thing I tackled and I replaced all the Transistors in the circuit and now they sound great. So I tested the SN76477N from the Explosion on the chimes circuit and that tested good and I tested the one for the main sounds and that tested bad just got scratchy chime sounds. So I reinstalled the good SN76477N from the Explosion sounds and put it in the main game sounds circuit and not all the sounds are right yet. Plus when I installed it I'm now getting a random "gun fire" shot noise that gets progressively get more and more as the game is on longer. I did notice that one of the switches in the drop target bank doesn't make the "Gun fire" sound when I push the leaf switch together all the others do. Maybe something with that will have to check. I replaced all the Transistors and Disc capacitors on the entire sound PCB which made a HUGE difference in the sounds. I'm guessing that there is still a bad IC on the PCB still I tested all the ones in the picture that are socketed with a chip tested. Unfortunately the rest I can't test with the tester I have so I'm going to have to figure something out.

I did add some jumpers for a logic probe and Traced the random gun fire signal up to the SN7432N location A chip I believe will have to recheck. I can see the signal pluse every time the gun fire sound goes off unless its related to that drop target SW it still has me scratching my head for the moment.

Yeah The Game just died again late Saturday night. I'm going after the power supply next because all I did was plug in a few light bulbs and the game flipped out and wouldn't come back. I don't think its a fan of the small filter cap going to order a big one like the one originally on it plus replace all the bridge rectifiers and 5v regulator and Resistors.

I just figured to cover all bases. I just rebuild a QBert power supply and matched up the size of the cap. Never had any issues after that. I just thought it was really weird the issue with the randomly repeating sound they way it kept repeating like a capacitor randomly discharging is what made me thing of. When I tested for 5v on the CPU it was like at 8v So something with the 5v has to be screwy. Then I just came to the conclusion if I'm going to replace the 3 Bridge Rectifiers and the 5v regulator whats the difference if I just replace the 3 big resistors and Capacitor just for good measure. I get everything I can from Mouser so the Capacitor should be good.

I just figure with stuff like that big cap has a hell of a drain on it and the bigger one holds a bigger charge so the smaller one is charging and discharging at a faster rate that a larger one would. It's just the way I like to do stuff try to match them up like they were originally made.
