Hi all,

My BK2K has been out of action for a while.

Coming back to it to sort things, it's now mostly okay but I have two
coils that won't play ball.

The left kick back (Sol 13) and the Upper Playfield lockup kick back
(Sol 7A).

I swapped them for new one's a while back and I foolishly I didn't
take enough photos at the time.

I'm all poised to replace transistors but before I do I just want to
be sure that they are wired correctly. Hi all,

me doubt it.

Left Kick back coil lies with lugs right side and has two violet and
yellow wires to the upper lug as the and the green brown on the lower
lug nearest the PF.

Upper Playfield Lockup kickback is lying with lugs left side. Violet
and black lead on the lower lug nearest the PF and a Yellow and violet
lead on the upper lug.

If anyone could confirm or correct this I'd really appreciate it.

Cheers,

JC

my bk2k has the 3 ball kick back sol. mounted with lugs to left of playfield-violet/black on top and yellow/violet on bottom

lower playfield is wired the same
good to see another bk2k owner around for help, stay on this board, Im always tinkering with mine to keep up with useage.
Have a ? for you
when you first turn on and press play, after machine has been off for a little while,does yours cause pop bumper lights and a few other lights to go out and a sound heard each time flippers are pressed for the first 4 times then it quits?not sure if its some sort of capaciter issue or if its normal.

Cheers for getting back with the info. I'm away from my pins for a while, and my machine is playing up but I can tell you although it sometimes takes a couple of on/off's to boot, it's never behaved like that, so yes it's worth checking something!

hey, as long as were checking wire locations, I noticed the flipper wires at one time had been resoldered so I am wondering about correct wire locations and diode directions for the 3 flippers in case they are wrong causing my problem, any chance you could give me your machinces wire color locations and diode directions on the flippers, on mine a solid green is used on 2 locations on each flipper, one going to the contact points , if you could break down which one goes there that would be great, I starting to think the wires may just be wrong but I cant find a descent pic clear enough on the web.Thanks
