Welcome Scrubby:
Specifically to your question about the books, I have both books that you mentioned. For me, and I am FAR from and expert, no one source is sufficient to solve all problems. Buy the books because you are already infected with the Bally Bug. Before long you will have 8 more games.
First. Post pictures both inside and out of the machine in question. We like pictures. Use several posts if needed to get all of the shots needed.
Second, Clean your contacts and connections, lubricate where needed, change blown out bulbs and then report SPECIFIC trouble issues. Hopefully there are none.
Third, Your best asset will be the fantastic men and women here on NLG.
Best of Luck
