Started working on a non-working Space Station I just bought. boards look clean as far as acid-burnt pins or connectors, or prior work being done. only a couple cracked solder pins. I did have to remove the small relay boards under playfield to re-solder pins to get my playfield gi back on. I have it to the point where it works to play a game but most of the solenoids are not working. The ones that are working are- out hole-pop bumpers-single drop target in front of ramp-left center kick out-that is it. The ones that are not working are -kickers (slings), drop targets, kick back, upper right and upper center kick ups. this is a lot things not working. At first I thought it might be the special solenoids -because I thought just the upper kick outs and slings were not working. Then I saw the other problems. I have re-soldered any cracked edge connector pins. Any ideas?

Thank you for the help I'll check it out and get back to you

Thanks for your help regarding my Space Station pin. I am happy to report that it is now fully working. I did what you said and found I had no power at the playfield on the items mentioned. I spent today re-soldering pins on cpu -aux power-and even checked the inter connect boards. I undid and reconnected all the playfield to head connectors. I'm not sure what did it-but it's up and working fine. maybe just a poor connection somewhere. Thanks again for your help. Matt
