Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor MECH-BATTERY-CHARGE Error Fix: Battery Will Not Charge or Drains Between Uses

Error code MECH-BATTERY-CHARGE on the Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor means: Battery Will Not Charge or Drains Between Uses. The battery goes dead between uses, requires frequent jump-starting, or the engine cranks slowly. Cub Cadet riding mowers use a regulated alternator/stator driven by the engine flywheel (15A on XT1/XT2). Causes: (1) OLD BATTERY — lead-acid batteries last 2-4 years. Replace if over 3 years old. (2) CORRODED TERMINALS — clean with wire brush and baking soda. (3) LOOSE CONNECTIONS — tighten both battery cable clamps. (4) FAILED ALTERNATOR/STATOR — with the engine at full throttle, measure battery voltage. Should read 13.5-14.5V. Below 13V means the charging system is not working. Test the stator output and voltage regulator. (5) PARASITIC DRAW — a short or accessory draining the battery when the engine is off. Disconnect the battery during long storage periods. (6) SHORT MOWING SESSIONS — if you only mow for 15-20 minutes, the alternator may not fully recharge the battery. Use a battery maintainer/tender between mowing sessions. (7) WRONG BATTERY — ensure the replacement matches CCA and group size specs.
