I need Gottlieb System 3 flipper rebuild tips. I've rebuilt both flippers and they are still very weak, not sure why. Help please!!!

Question 1: yes sir.
Question 2: no but they are in great shape meaning no cracks and I ran them through the ultrasonic cleaner a bunch of times and they look brand new upon very close inspection.
Question 3: yes they seem to run very smoothly when manually testing them.
Question 4: I have not tried jumpering the eos switch but I will. What does jumpering the eos switch do? Thanks.

I think it was the EOS switch's being very dirty. I cleaned them with contact cleaner and 1500 sandpaper and they now kick pretty strong. Thanks for the help. Much appreciated.

Hey Vid, pardon me if you already covered this previously in this thread but, I just installed all new flipper parts on my WCS, also new coils, everything from the roota to the toota. I still am not gettiing that snap I feel I should get from new flipper parts and coils. I also used the little gap tool when tightening down the flipper bats to the pawl and feel I got the gap between the flipper bushing and the flipper bat pretty damn perfect. Was I supposed to tighten the flipper piston and link to the pawl also? Thanks.

I mean that do not have the power or "snap" I would expect from all brand new flipper parts. When I manually move them they feel perfect, also I used the gap tool when I tightened down the flipper bats so the gap seems good. I'm not sure what else to check.

Thanks xsvtoys. I'll doublecheck the wiring in the manual when I get home.

Does anyone have a pic of how the wiring goes to the flipper coils on WCS ? I can't find a clear pic anywhere and the manual does not have any diagram of the wiring to the flipper coils. This is what I have right now. Pretty sure the right flipper is the top picture.

Thanks Vid. Should the power wire be on the banded side of the diode or middle lug or unbanded side of the diodes?

Thanks to all that helped! Much appreciated. I think maybe I'll adjust the gap on the flipper bats and see if that helps. The flippers aren't bad but they are missing just a little bit of power. Last time I did a flipper rebuild was on my Judge Dredd and when they were done, the power was unreal. I felt like I could have smashed the drop targets in front of the subway. Anyway, I must have something slightly off.

Hey Vid, could you step me how to test the voltage at the flipper coils? I tried with my multi meter but I am getting wierd readings and am not sure if I have it set right. Should I be pressing the flipper button once the meter is clipped onto the lugs? Thanks in advance. Here's a pic of my meter and the test clips I rigged up for it.
