TROUBLE SHOOTING GUIDE 15 TROUBLESHOOTING No Blue, Red or Green LED Indicators Check for loss of AC power at the 120VAC Ooutlet. Confirm GFCI (Ground Fault Circuit Interrupt) outlet has not tripped. Check with a meter or 120VAC test light that AC is present at the end or your extension cord. Confirm all charger cables are installed with the correct polarity connections at each battery and that all connections are clean and tight. With the AC Power removed and the engine off, check the charge level of each battery with a DC meter or handheld DC tester. If there is no charge level indication for a battery, check each battery with a hydrometer to determine if it has one or more bad cells. (batteries should always be replaced in sets, and always the same type.) If everything above checks out ok, contact MotorGuide for product service. Batteries are not Charging, but Blue and RED LED Indicators are “on” Confirm all charger cables are installed with the correct polarity connections at each battery, and that all connections are clean and tight. Reverse polarity connections will blow output fuse, resulting in no output voltage. With the charger on, read DC voltage at each battery. If any of the readings are less than 13 VDC Proceed with the following: A. Disconnect AC power at the 120VAC outlet. B. Remove charger cables from each battery. C. Reconnect AC power and read DC Voltage across each output cable, if output voltage is approximately 14.1DC the charger is ok and each battery should be tested with a hydrometer with the charger and engine off to determine if one or more batteries have bad cells. (batteries should always be replaced in sets, and always the same type.) D. If there is no output when trying to read DC voltage check each output fuse and replace as needed. If the DC voltage at each charger output is less than 13.0 volts contact MotorGuide for product service.
