I'm new to trying to fix any sort of old pinball/arcade machines so looking for somewhere to start. I have a Wico Big Top Pinball machine that I got from my parents. It used to work when I was a kid but now all it seems to do is light up, the flippers don't move, reset button does nothing, etc. 2 of the 3 buttons on the rear seem to work, 1 & 2 both turn off the lights on different sections of the machine, the 3rd won't seem to press at all. Looking for any info on how I can test this or any cheap parts I should try replacing right away? Only thing I've done arcade related so far is built my own MAME cabinet which is way easier than trying to figure this thing out lol.

Here's a site everyone needs to have bookmarked no matter what era pin you own.

Thanks! I'll start reading through that.

I also played around with the machine a bit more and noticed that all of the scoring still works. It seems that only the mechanical functions aren't working. I'm guessing that since the ball lift button doesn't work it isn't resetting something in the computer to tell the flippers and bumpers to turn on? Something for me to at least start troubleshooting.
 
There is now some repair information on pinwiki for this home model machine.

http://www.pinwiki.com/wiki/index.php?title=Wico

On the back of the power transformer box are three "push-to-reset" circuit breakers. As viewed from the rear of the machine, left to right are breakers 1, 2, and 3.

Breaker 1 (2.5 ampere) protects the backbox lights and power to the game board.

Breaker 2 (2.5 ampere) protects the playfield lights.

Breaker 3 (2.5 ampere) protects the 28 volt coils and the bridge rectifier for the coils.

Those type of circuit breakers, in general, are known to go bad mechanically and/or electrically.
