Go to the fuse that keeps blowing and follow the thick ( RED?) wires through its daisy chain to the coils. You may well be able to spot the faulty coil by burn marks or maybe one that is already pulled in.
If you cant find it, then keep the PF up... place another ( you may go through a few of these) fuse into the holder and turn game on from the bottom of the cabinet whilst keeping an eye on the coils that this fuse feeds... if one pulls in instantly and no others do, or if one starts humming, possibly smoking, then this is the faulty one.
You should be able to diagnose this visually if you have enough fuses ( BTW, if you run out of 3A Slow Blow... a 5A fast will suffice to do a quick fault find)
