Ok, have another issue with this Zac machine. I replaced the coil for the centre kick hole, but it does not seem to activate. I have made sure that power is going to the coil, and when I test with multi meter I am getting 38v. Any ideas?
Everything else works perfectly.
I am assuming that is the coil that was burnt out?
If it was then you need to check the complete ground path of that coil.
Coils burnt out when they lock on either from a bad driver transistor or bad pre-driver ic.
Check the driver transistor for that coil and if that is ok you may have to get out the drawings and trace it back to the IC that runs the transistor.
Not familiar with Zac's but they all work basically the same.
On my Timewarp Will sys3, the ball eject was burnt out from being locked on when I got it, but that also took out the IC that runs the driver, and when I got it going, the coil would not fire, I had to replace the IC and away it went.
