Its not charging and cuts off immediatly when turned on
My V-guard UPS doesn’t charging. If the UPS is plugged in there is no voltage seen on the battery side.
And my UPS is immediately shutting down when it’s turned on.
I don’t have 12v battery so I connect it with 12v adapter, if thats the problem.
I know the shutting down is done by a relay switch
How do I solve it
check the batteries inside. measure those voltages
