Troubleshooting
No LED Indicators
•
Check the 120 VAC outlet for power.
Make sure the GFCI has not
tripped and that all connections are good. If using an extension cord, use a
meter or 120 VAC test light to check for power at the end of the extension
cord.
•
Check connections.
Verify that charger cables are installed with the
correct polarity. Verify that all connections are clean and tight.
•
Check charge level of battery.
Remove AC power and turn off
engine. Use a DC meter or tester to check the charge of each battery. Check
each battery with a hydrometer to find bad cells if there is no charge level
indication. Replace battery sets together and use the same type of battery.
If indicator lights do not operate after checking the previous items, contact
Extreme Max for service.
