Glued and equally spaced the magnets to the fly wheel, and kept the broken one as tight as possible ( no glue between pieces).....let set up overnight, replaced the flywheel and started the engine, the amp meter is showing charge........I think it works. However what precipitated the disassembling of the fly wheel was negative charging when engine running. When PTO switch was engaged or brake released the engine would die ( Husqvarna YTH180 tractor). Figured there wasn't enough electrical power to engage the PTO (replaced PTO switch), engine still dies. The seat occupied switch seems to work, I will check the brake switch and see what happens.
