5. TROUBLESHOOTING GUIDELINE 

 

 
Please see the table below if you experience any problems with the Omnicharge battery 
charger and/or the installation. 
 
Problem 

Possible cause 

Remedy 

Omnicharge is not working at 
all. 

Main switch in Off (0) 
position. 

Push the power switch in the 
‘I’ or ‘II’ position. 

 

AC input voltage is out of 
range or not available. 

Make sure the AC input 
voltage is available and 
within the operating range of 
the charger. 

 

Remote switch or SAMLEX  
Remote Control has 
deactivated the charger. 

Activate the charger 
remotely or check if the 
remote bypass switch is set 
correctly. 

 

Poor contact between the 
charger battery wires and 
the battery terminals. 

Clean battery terminals or 
charger wire contacts. 
Tighten battery terminal 
screws. 

 

Blown DC fuse. 

Check battery fuse or 
internal charger output fuse 
(located on charger PCB). 

 

Very poor battery condition.  Replace battery. 

The battery is not being 
charged up to it’s maximum 
capacity. 

Incorrect absorption charge 
voltage setting. 

Check the battery type 
selector for correct settings. 
Or adjust the absorption 
voltage using SAMLEX 
Dashboard. 

 

Incorrect charge current 
setting. 

Adjust the charge current 
using the Universal Remote 
Control or SAMLEX 
Dashboard. Typically, the 
charge current should be set 
to 10%-20% of the total 
battery capacity 

 

Too much voltage loss in 
battery cables and/or 
connections. 

Make sure that the battery 
cables have a large enough 
diameter. Check if all DC 
connections are solidly 
made. 

 

Additional battery loads are 
consuming too much current 
during charging. 

Turn-off or disconnect all 
battery loads.
