For proper charging, it is necessary to plug the charger into the machine first, and then power up the charger. When the machine is fully charged, it will be necessary to remove power from the charger, allow the charger to shut down and then unplug the charger from the machine. When charging, the volts will be below 28.8 Volts and the amps will be in the high teens to 20.8 Amps. When fully charged, the amps will go to 0.02 or 0.00 and the voltage will go up to 28.8 Volts.

Do not leave the charger plugged into power when the charger is not in use. The charger will have the appearance of working properly when actually it could shut down the DC output voltage.

If the ProNautic Charger does not recognize a connection to batteries or the lane machine, or if it detects a bad ground or connection on the AC power side, the charger will not charge properly.
