As VFR said, use a kettle lead with a uk plug terminated on it.
Plug in to the mains and see if it powers up.
Check battery plug for output, set multimeter to a DC range higher than your charger output and test plug pins.
The charger specs indicate the output is protected by a T3.15. Which is a 20mm slow blow/anti surge.
You will probally have to take the case apart to change this, as the photos do not show an external
The way I see it is that the green light isn't on, which indicates no input , so the problem is on the mains side, not the output. In other words, he has no output because there's no input.
Possibly. If the output is current or voltage sensed and fuse has gone. Then the internal circuitry will stop led coming on...
