I have a 2000 BX2200. New battery, new alternator, new starter. It's as if I have a power drain even though I've confirmed the alternator is generating. Fully charged battery, mowed for 3 hours, shut it off and instantly attempted to start it. Dash lights come on but nothing happening at the starter. Not even a click. Put jump pack on, glow plugs click and it'll fire right up. Thanks for any assistance.
