Back when I was much younger I would have tried to trace an electronic
circuit board and replace components. These days I dont even touch
them, and just replace them. But battery chargers are such simple
things that anyone with some electronics experience can repair them.
Besides the housing, there are only 5 parts. The transformer, the
diodes, the "circuit breaker", the gauge, and some wiring (including
the external plug in and batt. cables/clamps). Also, some have a
switch to go from 6v to 12v. or low amp to hi amp. It takes me 5
minutes to determine the problem which is usually the diodes, but in
this one it's the "breaker". It takes another 5 to 20 minutes to
repair the thing. They're not complicated or hard to work on.
The problem is getting the parts.........

For those that said Radio Shack, they dont carry any diodes larger
than 1A, if they carry them at all these days. I rarely go to R.S. at
all anymore. All they carry is toys, and overpriced cellphones and
tvs. Their parts are limited to a few switches, solder, coax
connectors, phone cords, and a few grab bags of unidentified
semiconductors that (from experience) are often defective.

I should note that I DID repair a high powered batt charger using
diodes made for a auto alternator. Those diodes are way over the
rating of the charger, even for that 50A charger (which was an
expensive charger). The problem is that those diodes are also hard to
get, and most (if not all) are pressure fit and thus have no mounting
screws. I had to use the heatsink from the scrap alternator and mount
it into the charger while providing isolation from the metal case. I
did fix that one, and spent much more than an hour doing it, but for a
costly charger it was worth it.

I have 3 automotive 12v battery chargers that need parts. One needs
diodes, another needs that protection device that cuts out when the
leads short, and comes back on in a minute or so (are those called
circuit breakers or????). I am not sure what the 3rd one needs, but
probably diodes. (Have not opened that one). I hate tossing
something that needs a simple repair, but where can I get parts? I
tried google but as usual all I got were fu#^%&g links to ebay, and
spam sites.
