I do try my best to explain things when i am working on machines. I am always happy for the customer to look over my shoulder and ask me questions as i am working.
If you are unsure about the repair task then ask on the forum and wait until you have an answer that has been agreed apon by several members.
on the rare occasion when i come across a weird or strange fault i will even ask on here just in case someone else has come across the same problem and has a solution, this can save me hours of fault finding.
If you decide to try repairing a machine your self first thing you must learn are the danger zones (high voltage & mains wiring).
for example early bally and WMS SS and EM machines have exposed live 240vac mains fuse holders which can easily be touched when the playfield is in the up position and there are many EM's and SS machines with no cover on the back of the mains power switch just inside the door.
if you are unsure and even when you are sure make sure the machine is unplugged from the wall outlet and it's power source is via a circuit which has a safety switch just in case you forget to unplug it.
