12V Charger
I was given an old 12v car battery charger recently ,described as 'not showing any charge on the meter' and found it only gave 11.5 v on open circuit. However, there was a slight kick on the ammeter when connected across a large 10R resistor. It looks difficult to open as it uses 6 plastic breakable expanding plugs to hold the case on.
Before I start, what is likely cause of fault and will it be easy to fix?
