I have this Farfalla I am still trying to get up and running. Story was it played for years until a bad storm with lots of lightning and stopped working after that.

What I have done so far is replaced the 3 rectifier's, 4 Capacitors, CN1 header and pins, and fuse clips on the power board. I have tested the CN1 plug while disconnected from the power board and all seemed to be close to spec.

Test results on CN1 were
Pins 1,2 Red- 176.7VAC:
3,4 Brown- 9.9VAC:
5,6 Yellow- 10.8VAC:
7,8 Blue- 46.1VAC:
9/10, 11/12 Green/White- 7.1VAC:

I originally plugged everything back in at once and turned it on. CPU LED came on went off Sound LED came on went off, as CPU LED started to come back on I seen the F2 fuse glow and eventually pop. I then disconnected all boards but the power and CPU board, LED came on went off then fuse blew again. So then I disconnected everything from the power board while just leaving CN1 connected to the power board. More of the same F2 glows then pops.

I need some advice on where to look next. I havent used the TP's on the power board yet because I cant get power to the board long enough to test anything. The only thing I can think of is pins 1,2 on CN1 are higher than spec but I dont know where to look to solve that.

Bump for help

Yes currently I have only the main power connector (CN1) connected to the power board and it still blows F2.

Correct

Im at work right now. I'll get a couple for you later. Thanks for your help

Here are the pictures. I had read http://www.zaccaria-pinball.com/gen2/index.html and that’s where I got the part numbers to order them from. Everything seems to be in order. Please excuse the previous owners sloppy work I tried to clean it up as best as possible. I did notice the p2 rectifier doesn’t seem to be touching the heat sink. Could it be overheating that fast?

Ok so here is what I got. All these results are 2000k ohms because that’s the only range that would register on the meter.

~ to + 1816
~ to - 1394

~ to + 1562
~ to - 1610

+ to - tested ok
~ to ~ showed nothing.

I don’t see any shorts on CN1 but the solder for those pins are the closest ones to touching. I’ll clean up the solder and try again.

Tested all diodes. They are measured around .525-.550. I still need to try and clean up the solder on CN1

P2 is a new part. Game has never worked in my possession. Was told it ran for years until a bad storm one night. I'm half tempted at this point to buy another rectifier or just send the board off for a pro to take a look.

Look closely at the last picture. The close up of the rectifiers. There is a + mark on the board. It matches the + on the rectifier

At the same time looking at that picture it does look like the negative side of the cap is going to the positive side of the rectifier.

I think I have the fu***** capacitors backwards

The negative are stripes are facing each other. Guess its time to order more caps.

New caps came in and installed. Now F4 blows. I followed the trace straight up from f4 to p4 and it looks like it’s installed backwards as well as p1. I definitely didn’t touch those so I just want to verify those are indeed backward.

Also since fixinging the two caps f2 no longer blows and the game now boots to where the playfield now all lights up. No sound and displays yet but I’m sure that’s because of what’s going on with f4

Its about one second maybe two.

Thats exactly what fixed mine. I bought new caps installed them the correct way and everything works great now.
