What to do if Magnum Energy Battery Charger is auto reconnecting every 10 seconds?

  Mary EscobarAug 5, 2025
  If your Magnum Energy Battery Charger is auto reconnecting every 10 seconds, and the voltage requirements are met, the current sensing may be faulty or the current might exceed continuous capabilities. Allow the charger to enter Float Mode and recheck the status. If the ME-SBCTM continues toggling, it could be defective; otherwise, it's likely operating as designed to protect itself.

  If your Magnum Energy Battery Charger is not combining, check the voltages at the Power Terminal Block. If the voltage between #1 - MAIN POS (+) and #3 - COM NEG (-) or #2 - AUX POS (+) and #3 - COM NEG (-) are above the connect voltage and the difference between them is less than 10 VDC, the ME-SBCTM may be defective. Contact Magnum for assistance.

  If your Magnum Energy Battery Charger is not disconnecting, remove the fuse at both batteries and check the resistance at #1 - MAIN POS (+) and #2 - AUX POS (+) on the ME-SBCTM. The resistance should be approximately 600k Ohms. If it isn't, the ME-SBCTM might be defective. Contact Magnum.
