right now the battery light is on and the mower starts and runs fine until the blades are engage and load is put on the system. The ignitor in the distributor has been replaced, coil, coil wire, plugs, battery, alternator, and the rectifier or voltage regulator have all been replaced. also if you turn the lights on it kills the mower. any ideas I'm all out and so is my local grasshopper dealer after $850 and mower still don't run properly
