  Terry EdwardsJul 31, 2025
  If the ammeter on your Charles Battery Charger deflects counterclockwise, it usually indicates a wiring error. Immediately disconnect the unit and double-check the wiring instructions to ensure proper connections. Counterclockwise movement or a full-scale movement suggests excessive current. You can use a voltmeter to monitor the battery voltage when the charger is on; you should see an increase in voltage when power is applied.

  If the internal red LED on your Charles Battery Charger is illuminated, it means the unit is operating at half-power because the ambient air is too hot, or the fans are not working. Once the temperature returns to normal, full power will be restored automatically.

  Richard KnightNov 5, 2025
  To determine if the issue lies with your battery or the Charles SP series C-Charger, first, ensure the ammeter reads zero. Then, turn off the AC power to the charger and disconnect the battery for at least one hour. After this, connect the battery to an ohm-volt meter. A reading of 12.6 VDC or higher is ideal. A reading between 12.4 and 12.6 indicates a 75-100% charge, while 12.2 to 12.4 VDC suggests a 50-75% charge. Consult your battery's manual for further instructions. If the battery seems fine, verify the input voltage (120 VAC), check the charger's AC and DC fuses, the battery fuse/AC circuit breaker, and all wiring connections. If these are working, test the charger's DC output by disconnecting all DC outputs, turning off AC power, and then reapplying AC power. The DC voltage between...
