You should first check the charger itself. Disconnect any batteries by removing any connected charger cables and plug the charger into an AC power plug that is successfully connected to the mains (220V) ensuring that the plug has already been checked and working correctly. The display should light up for a few seconds and the ‘ON‘ LED light should be visible.
You should then be able to push on the selection button to activate the display and/or go through the different selection modes –
- 12V, Turtle & STD
- 12V, Rabbit & STD
- 12V, Turtle & AGM
- 12V, Rabbit & AGM
- 6V, Turtle & STD
The next step is to test the charger when it is connected to a battery. Connect the clamps to a battery, connect the charger to the AC power and choose a charging function. If the charger makes a ticking sound for a few seconds and then starts to charge, the graduations go up and down and the battery voltage is showing (and going up) then the charger is working correctly.
If you face any issues with any of the tests above and the LED lights and/or display screen does not work correctly or light up, then there is most likely a fault with your charger. Please contact us for further advice using the “Contact Us link at the bottom of this page.
