Just when I was feeling good about "shopping out" my first machine, I have hit a roadblock and am feeling like I'm in over my head. I just rebuilt my upper flipper on my BK2K after it started being extremly "lazy" last week. It was working great after the rebuild kit was installed. Today I rebuilt the right lower flipper (I figured if one was going bad the others aren't far behind). While resoldering, I unknowingly switched the two wires going to the EOS switch. When I turned the machine on and tried the flippers, the right flippers didn't work. Once correcting my mistake (and replacing the fuse in F5), I tried the flippers again. This time the lower playfield right flipper worked great, but the upper playfield flipper (right) was only slightly "jumping". I happened to have a new coil so I swapped it out. Unfortunately, I read my wire labels incorrectly, and I wired the coil incorrectly (I switched the wires going to the outside lugs) (burned another F5 fuse). I have now replaced the fuse, turned the machine back on to test the flippers, and the upper flipper doesn't even "jump" the slightest bit. And it burned the fuse after trying the flipper only a few times. I am now stumped. I do believe I have the wiring correct. Did I burn something else out besides a fuse? I don't know where to turn. Please help

Probably a stupid question, but what do I measure with my multimeter to determine if the diodes are cooked?

I think that sounds pretty accurate. I will change out the coil, install new diodes, and rewire correctly. I will post pictures. Back to work tomorrow. I will post when I've had a chance to work through this. Thank you.

Well I delved back into this dilemma. I have gone back to the "original upper coil" just in case I screwed the "newer one" up with my f****** up wiring. I have installed new IN4003 diodes with the bands going in the same direction on the coil. I have rewired it according to my original tags and photos (the issue was not my labeling prior it was reading them incorrectly). I am a little confused as in reading the manual on page 48 (assembly notes #9) it says "Solid color blue wire connects to the banded end of each diode, mounted on the connector end of the Flipper Coil (item 9). Trace color wire connects to the unbanded end of the diode". Looking at my original photos of the "untouched by me" coils, they don't seem to be wired this way. I have not turned on the machine at this point as I am nervous to do so. I am hoping someone can look at my "before and after" photos to see if things look correct or not. The coil with the original wrapping is the upper playfield flipper prior to my involvement with it , the pictures with the masking tape wrapped coil is the lower playfield right flipper. I will post more pictures. Thanks again for the input.

Hi Robertmee, Thanks. The bottom flipper is the first batch of "after" pictures. Everything looks good to me except my "blue-yel" wire to the upper flipper is plain blue. I am thinking that is has been replaced at some point. I do know that the "plain blue" is wired in the same location I originally removed it from.

I have confirmed that the "plain blue" wire is connected to the J2 pin 5 location in the upper playfield interconnect board (it is a replacement wire). I have confirmed all my wires. Now the upper playfield flipper won't "stay up" and seems lazy. I can hold the bottom right flipper to hold a ball and the upper flipper even though it worked won't stay in the up "engaged" position. Any thoughts?

I'm assuming you mean the three single strand (one is a thick and thin) wires coming off the coil itself and going to the three lugs? I just checked those, and found one loose on the lug end. I have resoldered it and hopefully that will do the trick.
