[NOOBS]: New to World Cup Soccer?
I hope this is not presumptuous to post this, but I don't know if there has been a post of basic "things you should know" about how to troubleshoot this pin. So, here is my starter list for anyone new. So, here are some basics...
When you get any new pin, after cleaning it, I believe the best thing to do is to use the built in tests. Learn how to use them, and understand how the switch and light matrix works. This requires a manual, or at least those pages with the maps. Most issues you encounter will be diagnosed, and likely solved using this basic information. Getting more into the electronics, I think it is important to understand the purpose of the diodes on the switches. It should also be understood that all of the IR sensors (ball through, etc) are actually on the matrix as well, translated through the board below the playfield, under the left slingshot. Having a basic knowledge of a multimeter is also helpful. To learn about all of these things, I found that Ray's Tech Tips on YouTube provided all of this (if you can get past the sarcasm of the idiot that film Ray in the episodes).
For mechanical issues, like electrical issues, step 1, if you need help, should be to use that search box at the top of this page. Odds are, the issue has already been discussed long before you got here. Though new, unique issues do happen.
Mechanical issues are the most frustrating... The diverter has been widely discussed, and I have personally posted about it a few times. The goalie is prone to breaking (plastic and wiring), because let's face it... That guy takes a beating.
For replacement parts, I always look to Marco Specialties first, just to identify the part I need. Then, I may go to ebay or elsewhere, depending on the need. I also like Marco for the basic LED conversion kit, but I know there are many others. I have purchased lights from many places, and there are many varieties, not all of which are worth the money.
EDIT: Cleaning... Keeping a machine clean reduces wear. Novus 1 & 2 are highly recommended. 1 for basic cleaning, 2 for deeper cleaning of the soccer ball, flipper rubbers, and some other areas. Maguiar's Carnuba Wax is great for the playfield. Replace balls annually! If they get pitted, or start to rust, that is abrasive on the playfield. Rubbers are all wear items, and I get mine from Marco.
EDIT: Get a Reed Switch Adjustment Tool! (bent rod with slots in each end, search marco) Don't bend your switches with a plyers, as it will do more harm than good.
In summary... If you are new, get a copy of the manual, learn the matrix, search the forum, and start with Marco for parts. Ray's Tech Tips is a great knowledge base, and many in this forum are welcoming to questions, and most problems get solved in short order.
I hope this post is useful to someone out there, as I used this forum a lot in the beginning, and would like to give back where I can.
