Why won't my Schumacher Battery Charger engine start?
- CCharles KennedyJul 29, 2025
The engine start function may not work due to several reasons: * If cranking draws more than 150 amps, crank time may be less than 5 seconds. * You may have failed to wait 3 minutes (180 seconds) between cranks. When the Engine Start LED blinks, wait 3 minutes of rest time before the next crank. * The charger may be overheated. Make sure the charger vents are not blocked. Wait and try again. * The battery may be severely discharged. Use the 20A Boost rate for 10 to 15 minutes, to help assist in cranking.
