Why doesn't the engine start with my Schumacher FARM & RANCH Battery Charger?
- NNicholas JohnsJul 29, 2025
The engine start function may not work due to several reasons: * Drawing more than 100 amps can reduce crank time to less than 5 seconds. * Failing to wait 3 minutes (180 seconds) between cranks. * The charger may be overheated, or the battery could be severely discharged. To resolve this: * If cranking draws more than 100 amps, crank time may be less than 5 seconds. * Wait until the display shows “rdy” for the next crank. * Ensure the charger vents are not blocked and wait for the thermal protector to reset. * For a severely discharged battery, use the 30A Boost rate for 10 to 15 minutes before cranking.
