Where is the 3rd fuse? I have dis connected coil as suggested and I am no longer blowing fuses
I am also testing voltges on coils and this is what I get
Knocker :38v
slingshots: 0.4v
Flippers:    0.4v
Pop bumpers: 38v
Ball eject: 0.4v
Drop targets: 0.4v

So now back to my original problem, no ball eject, slingshots, or drop targets. Apart from that machine plays fine.
Thanks for your help so far, I am learning heaps. Hopefully we can get to the problem.
