  If the Engine Start function on your DieHard Battery Charger isn't working, it could be due to several reasons. You might be drawing more than 250 amps, which reduces crank time. Ensure you wait 3 minutes between cranking attempts, especially if the Engine Start LED is blinking, as the charger's thermal protector may need time to reset. Check that the charger vents are not blocked. For a severely discharged battery, try using the 40A Boost rate for 10 to 15 minutes before attempting to crank the engine.
