I recently picked up a SS joker poker cosmetically in great shape. The previous owner stated I was getting a machine that hadn’t been “monkeyed” with... WRONG ! He had stated a few drop targets didn’t drop when hit so I had a complete new set and replacement springs waiting. When I lifted the playfield up, the drop target housing (10,JJ,QQQ) was hanging by four or five wires. I proceeded to replace all drop targets and springs as needed. Then I reattached the drop target housing to the playfield. I’m no expert, but I’ve learned quite a bit in the last few years with this new hobby, starting with target alpha, card wiz and a bow and arrow..anyway, l lowered the playfield and hooked up all the wire harnesses to their corresponding boards in the back box and turned the machine on expecting the worse. To my surprise, the game played! Until...I noticed some drop targets scoring correctly while others scoring way too many points. For example: the upper target bank of A’s from left to right A-scores correct, A-scores correct, the joker and A next to it score extra( if I had to guess, 2500-3500 points) then the far right target scores correct. Other banks have similar problems, both JJ’s and the middle Q do this. Also one or more of the roll over lanes at the top of the playfield do this...I know this is long winded, but I’m trying to get as much info initially here that I can. Looking forward to the advice from the experts on this site !

Thanks in advance

Thanks, could it also be board problems? When the target is dropped, aren’t the leaf blades switches supposed to make positive contact until the bank resets or resets after the ball drains?

Ok, I’m up this weekend where my joker poker is still trying to diagnose the scoring issues. Looks like the roll over and drop target switches are fed to MPU via the A1-J7 Molex connector. This connector has 17 slots for pins with two slots, (5&9 being spares)... the book and pictures I’ve been able to find show 15 wires in the connector, however I only have 13. Slots 10 &11 are empty. Now, someone before me cut the wires and they have been reconnected with butt connectors...I thought I may have found the problem, but when I count the number of wires coming from the playfield, and before any cutting, I still only have 13, and the “bundle” of wires wrapped with that was string stuff doesn’t look to be compromised in any way. I’ve been staring at the bottom of the playfield for hours and don’t any extra wires. Puzzled. Help !!

Any thoughts on the all in one Pascal board ?

Thanks for the response...somewhat comforting...any clues to my extra scoring issues ? Also , I was up where my game is this past weekend, and the Q bank and K bank stopped scoring all together along with the single roll over 2/3 up on the right side. Once the ball drains though, the target banks DO reset, telling me there’s at least some kind of communication

Calling all experts!! New problem on joker poker. Started off the day trying to figure out why none of the 11-10 value switches would score...Found a bad switch using the test mode, I replaced it and they all work. Then I started trying to figure out why none of the queen’s would score ... using jumpers underneath the playfield I could get them to register for score, I suspect bad ground on one of the three switches. I was using voltmeter When one of the wires made the weight that causes the game to tilt touch the inside of the opening, which did in fact make the game tilt. Now I’m stuck. Here’s what happens now, when you power up the game the displays shows zero immediately instead of the normal five second delay and then after about 20 seconds the game tilts. Also, can not access the self diagnostic test...I was able to use this earlier diagnosing the other problem. Of everything I’ve read it says the slam switch and the tilt switch have to be closed for the game to work, to which they are...I hadn’t even touched them... any help would be appreciated because I’m completely stumped

Any help out there? For clarification, when I said one of the meter wires touched the hanging tilt rod, I was referring the meter cord.

Installed a pascal all in one board in my joker poker. Seems to have restored the original game play. Few questions...

1. Should 500 points be awarded when ball is ejected into shooting lane?

2. Left “J “ scores 11,500 points on first ball and lights up 5x ( right “J” still up) I don’t feel that this is correct

3. 2nd “K” (red) from top scores 7000, 20,000 or 25,000 on first ball... seems random ...also resets without any of the other K’s knocked down

4. Upper roll over “B” ( middle) scoring 2500 unlit , should be 500

5. Middle “Q” on first ball scores 20,000 and resets Without the other two queens knocked down

Yes... board is set for joker poker. Points awarded when ball ejects to shooting lane has stopped.

Thank you for the response. I’ve checked and rechecked...all wires are in fact going to the correct pins in the edge connector. Pascal himself responded today and feels the problem could be a bad diode or diodes mounted on the Bakelite under the playfield. I’ve checked these but not 100 percent sure I know what I’m doing in this area. He said it was good that i discovered the switches scoring extra points all ended with a 2. That strobe return is pin #4 on the A1-J7 plug. It will be another week before I can get back to where the machine is, but I think I will go back well prepared...Thanks in advance for anything And extra help
