Hi,

I'm finishing up a full rebuild of my Rocky & Bullwinkle and just ironing out the last few issues.

The big problem I now have is that if I hold one of the flippers and manage to make a loop shot then typically when the ball bounces back down to the flipper it causes it to drop. It's almost as if there is something wrong with the hold voltage.

The issue appears to affect both flippers, but it's more noticable on the right simply because it's easier to hit the left loop shot so it happens more regularly.

So far as i'm aware Rocky & Bullwinkle doesn't use EOS switches and both flippers on mine have had full rebuilds.

Can anyone please give me some pointers on what I should be checking to address the issue? I seem to also recall that i've fitted new fuse holders on the flipper board (I say recall as this build has been ongoing for about 3 years).

Any suggestions gratefully received

Pete

Not at home so dug through my pictures. It's a TY-FFASI-2006 - part number 520-5033-00.

The picture below is from when I replaced the fuse holders I think.

Sorry for the n00b question but should the voltage on the coil be AC or DC? Bit confused because the schematic for the flipper board shows the 50v as DV and the 9v as AC.

Does that mean I should see 9V AC on the coil plug when its holding?

Now sure how I can measure the 50v as it only stays on very briefly. Any ideas Russ om how to troubleshoot this dropping flipper issue please?

If I set my meter to DC and put it on the lug with the blue and yellow wire on the right flipper coil I get 6.5v when the flipper is held. Is that a little low?
