I am new here so be gently. I recently purchased a Bad Girls pinball machine( my first) . It is so 1980's and tacky that it fits in well. It had some typical major problems, battery damage, bad bumper driver card, etc. It took me about a month to get everything repaired. It was actually a very fun product, very challenging to say the least. Anyway I have everything working properly with exception of the lites that show which targets have been hit during the rerack bonus. This is after the 1-7 ball drop targets have been dropped. If you hit them manually you get the rerack bonus however the lites in front of each target should be lite and then go out after the target is struck. I am having trouble figuring out which transistor is suppling power to the lites, etc. Any help?
 
It's all about the "cheesiness" factor in the era of Gottlieb but damn some of these are real gems!!

Do you have the manual for the game? If you don't my suggestion to you is start from there! Steve Young has at Pinball Resource has this particular one...Too bad I had a extra one couple weeks back but gave it to a buddy.....

the connection appears to be fine, I went through all the boards and cable connections, cleaned them and put them back. It would seem that connection to "turn them on" would be the one at fault, or the one that would "reset" once they were all turned off or the end of the rerack segment. This I believe would be on the driver board but then again I found bad transitors on driver aux diver boards under the playing surface, I have the schematics but am just not that good at telling.
 
I don't have the schematic in front of me but open connections between the driver board and MPU could cause this problem (clock lines for logic). Obviously there could be other causes but since you mentioned corrosion that's what first came to mind.
