Sometimes trying to find things that need to be adjusted or replaced can be quite frustrating on a EM pin. I do not know your EM diagnostic level but if I were you I would wait for the schematic to arrive and learn how to read it if you don't know already. Then go to "pinballrepair/em.com" and read from start to finish what Clay has to say. He is one of the best in the game for diagnostic/repair. He will also tell you the start up sequence. Follow that sequence with the schematic in hand to run through the process. For any parts you might need for your Gottlieb pin call Steve Young at "The Pinball resource" (PBR) for all your needs, he is the cheapest most stocked guy around for Gottlieb parts. While you are waiting for the schematic go to Clay's site and do some reading on EM's.
Lastly, did the pin work 100% and this started after transporting it to your house?
Once again, I do not know your level of EM repair and I did not mean to apply you know nothing, I just wanted to give you my opinion on how I would start the diagnostic procedure. Good luck and have fun with the pin.
