I have a pink Chinese Vector VEC074 Automatic Battery Charger with "Start Assist".
The circuit breaker is supposed to protect it, but at high rate of charge on a dead bat-tree (12V) the smoke was let out of it.
I was not attempting to start the car on start saasist, just charging the battery.
It still "hums' so it appears that the A'C transformer is still good.
I believe that just the rectifier/diode was blown by some amazonian electrons.
Can I just replace the diode/rectifier ?
Where can I find parts ?
Where can I get a schematic ?
Since a battery does not need pure DC to charge it, is this simply a regulated pulsed DC output ???
It seems to "start assisst" you can simply take the secondary A?C and rectify it with no regulation at high current, which is switched with the front panel selector.
When charging a regulator is switched in to vary the rate of charge. This does not allow for high current as is enabled in start assist mode.
Part of the unit still hums and works as I switch modes , however there is still no out put voltage, which leads me to believe that the transformer is ok, and just the rectifier is destroyed.
Any help ??????????
