I bought a charger to charge car battery, has Ammeter in front.
When turned on for hours the Ammeter doesn't move to show how much current flows to the battery and when opened to look if anything wrong I found weird design.
They attach one wire directly from the transformer to the positive terminal (battery) and the negative attached to circuit has 3 mosfet IRF1404 L and no rectifier in the circuit.
Any ever seen such design?
