What to do if Schumacher SE-1555A Battery Charger has short start cycle when cranking engine?
- CCrystal ForbesJul 31, 2025
If you're experiencing short start cycles when cranking the engine with your Schumacher Battery Charger, it could be due to drawing more than 150 amps for 3 seconds or less, or not waiting 3 minutes (180 seconds) between cranks. Crank time varies with the amount of current drawn. If cranking draws more than 150 amps, crank time may be less than 3 seconds. Be sure to wait 3 minutes before attempting the next crank.
