Killed W?D Wrong Cap?

I have just replaced C30 on my W?D whilst trying to rule our causes for the steppers tripping F116 when plugged in.
I'd changed BR5 a few months ago and just got my hands on a (what I thought ) was a C30 equivalent. I picked up a cap 25v 15000uF locally and switched it out.
Prior to switch out I was getting 27v unreg. Once I changed it it dropped to 9.4v.
I plugged in the steppers and all good no blowing of the fuse.
Only thing is though, the flippers started flickering occasionally through the game and they didnt feel as strong as the did prior.
In the second game though ... The left flipper has stopped working.....and both are very hot.
Desperate for a quick fix as my dad is visiting for the first time since I got here and after talking it up so much Its not gunna look good.
Any thoughts ????

Lost the Left flipper now.
Where do I start???
Did flipper test. No power or hold on the left. Have power on the right and hold only if i manually lift it to the hold position.
Opto switches work.
Knew I shoulda left good enough alone!
lol
Any tips before i start googling?

Seems that cap30 not soldered correctly and dropping the UR12v to 10v blew the flipper fuse.

C30 "smooths out" the output from BR5. If that output isn't smooth, then you can
get weird stuff happening with your optos, which could cause your flippers to act
all crazy.
Have you replaced BR5? I'm wondering if your bridge doesn't have one leg out, and
the cap was doing a herculean effort of trying to keep the voltage up.
Though if you're having problems soldering C30 in correctly, no offense but maybe
you need to find another pinhead in your area to show you the ropes on how to
solder correctly to boards. A bridge is 2X as hard as a cap to solder in, due to
having 2X the number of connection poitns. ;)

Wait, hang on there, you're going a thousand miles a minute.

Im hearing ya Korn.
I replaced BR5 earlier on whilst trying to discount reasons for the slots blowing F116. So now BR5 and C30 are new. The issue with C30 was with lack of flow through to the BR side. Guess I've learned that the hard way but learned it all the same. I am a noob to PCB soldering and so far just replaced the BR, Cap, and a couple of tip 102s. The last "Tech" seems to have had an aversion to removing transistor legs and has cut them off on the component side and soldiered a tip102 and a 107 to the old legs in stead. A little messy but they are doing the job.
I have been practicing on an old Stern 100 board and have gained a little confidence by no means ready to replace ICs etc.
After our last convo re W?D schematics on IPDB or lack thereof I have scanned the missing copies. Im not able to amalgamate them into one doc in order to send it to IPDB though.
You mentioned that you might be able to help me out if you had access to them IOT trouble shoot these steppers blowing F116. Whats the best way to get you access to them If your still keen for a look?
I really appreciate any time you can afford to help out.
cheers

exactly the problem you encountered. (I'd rather top and bottom solder a
component if I run into that problem.) i.e. still valid, just... messy. No style

Just email them to me... thekorn at thekorn dot net. ;) Unless they're way too
big for email, but I kind of doubt that. If they are I have an ftp dump site you
could put them on, or put them on rapidshare.com .

Though not a technique I personally subscribe to, that technique does avoid

I always thought the reason this was done was because the tech was lazy

and probably didnt want to hassle with removing the board. This type of
hack job can be done while the board is still in the machine lol.

I dislike that, but it can be a valid technique to use when you don't have

the right tools for the job. If all you have is a soldering iron, it's
better to do this than to screw up the holes and pads trying to clean out
the holes.
