I just purchased a Batman Forever and tried my best to "shop" it out. I stripped the playfield and added all new LEDs and rubbers. My hat goes off to all you pinheads out there that do this with your eyes closed because I'm a complete newbie to this amazing hobby and found it very tedious, borderline difficult. So I then cleaned and waxed the playfield and put everything back together. Game was amazingly beautiful with the Cointaker LED kit and that darn Silver ball was bouncing all over the place with the new rubber kit.(most of the rubbers hadn't been replaced and were hard like plastic.) But, I noticed the right flipper wasn't strong enough to make the ramp shots. Again, turning to this site I learned that maybe replacing the flipper coil with a LOTR special coil would solve the problem. So I did. And like many others, I may have wired it backwards because it didn't work. I checked the fuse...yes it was blown...I checked the diode...it too was wasted. So I flipped the wires, replaced the fuse and put in a new diode. Turned the machine on and as it was going through boot up, the right flipper shot up, and then went down and wouldn't work again. Another blown fuse, but, the diode seemed to be okay. I tried looking at the manual but couldn't make sense of it.(Sorry, complete newbie here armed with a MM and a retired electrical engineer father as my right hand man) I've read that I may have also blown a Transistor...could someone please tell me where to find it, how to test it and replace it? Thanks in advance...

Okay thanks for all the advice. And yes, I need to take pictures for sure! I learned that after taking apart all the ramps and wire rails!!!
I guess I really need to know how to find that blown transistor? I have the manual but I'm having difficulty finding that information. Can anyone tell me where it is located? Is that a part I can get at Radio shack? Radio shack had the fuses and diodes...

I finally figured out which transistor was the culprit. Big thanks to Mike from Pinball Life who taught me how to test the transistors with a MM over the phone. I just did my first solder job putting the new transistor in and it worked!!! Thanks to you two for replying and helping me find a solution.
