I just finished repairing the charging system on a 318. The stator winding had the first coil at one end of the stator winding shorted to ground. This shorted coil was in effect bypassing one of the diodes in the regulator and causing a short. The thing is that the stator still showed good voltage across the stator leads, but connection an ohmmeter from either stator lead to ground showed it to be shorted to ground. The stator coil that shorted had quite a build up of oily grass clippings, so I suspect that blocked cooling enough to burn up the coil insulation. Check that out, the stator leads must read no leakage to ground. Not a real easy job to replace the stator on a 318, you need to remove the engine. That adds a couple hours work to the job.
