Hello Everyone,
I looking for anyone that might be able to help with an issue i'm having with a allied leisure boogie. It will coin up and when I press the credit button to start a game it will kick the ball out like its ready to go but it will not select the number of players or ball in play. It seems to play somewhat correctly but does not score and when the ball drained the playfield resets and it kicks the ball out again ready to play. I have checked and cleaned all the cards and reseated all the connectors but still doesn't work. I checked the 5 volt regulator and it good with "4.8 VDC " Once after reseating the player up and lamp driver it started to score and showed the player 1 light but would not roll to player 2,4 or 4 or change from ball in play "1" but after power off and back on it went back to its current stat of not working .
Any help is greatly appreciated.

Thanks
Bruce

Thanks for the reply,
I have used the pinwiki article previously and fixed a few other issues on the machine.
I will check all the connectors and re clean them to see if that corrects the issues.
Yes it completes the reset sequence, both at the start od a game and when the ball drains.
from the guide clip below it completes step 4 but nothing on step 5

I checked all the connectors and found a few that were corroded and cleaned them the reseated all the cards and turned it back on. Not much changed the displays looked a little better and a few more lights on the playfield work but that's it. I did notice that if I add 8 credits ant then press start 5 times the LD 32 light on the player up card lights up and if I press start again it goes out then the LD 33 light lights not sure what these do because on the player up card it says they are 11 and 14 pins but on the main print they don't show on the player up pin out. Don't know if that has anything to do with my issue but its a new item Clips of prints attached.

Also is 4.8 vdc ok for the 5 volt regulator or should I replace it ?

I also replaced the IC 22 on the player up card it was a sn7442an chip and the new on is a dm7442n chip does that make any difference ?

Ill be back troubleshooting tomorrow .

Thanks
Bruce

Thanks for the info ill get some of the of the pins and connectors .
I did some more checking of the 5 vdc and found it to be 4.75 at the cards so I pulled the shroud and found that someone previous to me had changed the regulator to a LM323 which is not the correct one only rated at 3 amps so ill look into changing it back to the correct regulator if I happen to have one in my stsch of loder electronics or update it to an adjustable one .
Ill keep everyone updated when I get it changed.

Thanks

Just wanted to update both of you.
I received the new regulator and installed it . I now have 4.95 vdc but still had the same issues. With a little more testing I found that the head box lamp driver card had a shorted cap and that was drawing down the system now that that is corrected I now have all the lights working and the player 1 display flashes as it should . But I have a few new issues the 10's will not score and the chimes only sound briefly when the machine is powered up. it seems to be stuck in same player shoot again mode as the slights flash until the launch a ball but then they stay on solid and that repeats forever. I don't see anything on the player up card that looks suspect and cant seem to figure out what makes the game trigger the same player shoot again logic any help is greatly appreciated.

Thanks
Bruce

Latest Update.

I did some checking with a logic probe and found that both IC1 and IC 9 were not functioning correctly IC1 had a visible burn spot on the under side of the chip. Very difficult to see when the chip is in place. Both IC's have been replaced. I put sockets in place for easier chip swaps if ever needed
Testing with the newly chips in place seemed to fix the shoot again issue but also produced new issues. the score for the current player no longer flashes before the ball is put in play. although it does now light the player one and ball in play 1 light as well as players light but if you select more than one player the machine tilts as soon as you press the button to add a player
Could this ne an issue on multiple card's ? or something I did during the chip update?
Would anyone with a working boogie or sister pin be willing to test my cards to verify it is either one of them or an issue somewhere else ?

Thanks
Bruce

Thanks for the info.
I cleaned all the boards and did see a little improvement still tilts but now it seems to play a single player for a longer time then just tilts out of the blue its like something is heating up and opening the tilt circuit. Ill keep looking and hopefully find the faulty chips soon

Thanks
Bruce
