Thanks guys i found the problem the solenoid wires on things kicker was wired incorrectly i checked my teardown photos and it was wired wrong when i got the machine 50 Volt DC was looping through the coil and was affecting other solenoids as well.
I would have thought i would have been blowing a fuse as the negative wire was connected with a 50 volt positive, I didnt check before i fixed it but im guessing the negative wire was connected to the looping out 50 volts.
Now all the kickers are too bloody fast .

Cheers
