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
McMaster-Carr and DigiKey are two potential vendors that come to mind.
Also Grainger, but they won't sell to you unless your employer has an
account (even if you pay with your own credit card.)
replace "roosters" with "cox" to reply.
Also try Mouser Electronics,
http://www.mouser.com . You can order on
line, with no minimum. They have a huge
inventory and their on-line
system tells what is in stock or not.
BTW, they don't add huge S&H
charges either .... only the exact
shipping charge for the items you buy.

Start with Radio Shack and places line
You have to learn to use Google. That is where the above links came from
and none are spam sites of ebay. I got 76,000,000 hits but I did not check
them all out.
I have had no luck finding anything useful at Radio Shack in the past
few years. The local store employees for the most part give you blank
looks when you look for basic stuff like resistors and diodes. (have
needed same on short notice before for work.) Anymore I go to a local
place called Arcade Electronics first, but that probably doesn't help
replace "roosters" with "cox" to reply.
My business is repairing roll laminating machines, and buy parts where
I can to save BIG BUCKS.
GBC has a board thats near a 100 bucks where a 10 dollar transistor
fails. So I buy and swap that transistor to save money, its as good as
a new board and saves near 90 bucks:)
Most of the Radioshack stores around here closed last year but that
didn't matter because they had very little stock and as you said no one
knew what you were talking about.
We used to have two great industrial supply houses in the area but they
are gone because there is no industry here anymore.
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.
Member of the 'throw-away' society; eh Tony?
Have to agree that if/when one has to pay North American labour rates
it is often not economic to 'pay' for something to be fixed!
Also to 'pay' for something to be fixed usually means driving
somewhere or having someone come and pick it up, repair it and return
it (or pick it up yourself). With the consequent use of gasoline etc.
However anyone willing to reuse/recycle should be commended.
My quick, back of the envelope, calculations seem to indicate that any
significant project I can tackle personally can often be completed for
one third the cost if one does it oneself, especially if one has
mostly used materials on hand or saved up for it. Repairing an item
such as a battery charge from a few extra bits on hand or purchased
could possibly be done for just a few dollars. I too have couple of
such chargers and another to scrap for parts. A few years ago rebuilt
one of those 'heavy' chargers that can give enough current to start a
vehicle or recharge a battery in 20 minutes. It had been thrown out by
a local auto repair outfit who said "take it". Some $40 later and with
the addition of a missing handle replaced with one from a scrapped
'weed eater' it is good as a new $250-$300 one!
I congratulate the OP for thinking about refurbishing, reuse, repair
or recycle whatever you want to call it. We should all be thinking
If everyone saved and re-used broken things and scavenged them from others, what
would happen to our economy? And where would I get all the great stuff that
makes my life cheap, easy, and interesting?
It was common practice until somewhere in the 1980's for people to
repair things. This disposible society is actually something new.
The economy in the 50s thru the 80's was no worse than it is now, and
selling parts was a business in itself. What we do now is fill dumps
with tons of junk, and deplete our resources, while buying inferior
products. I know that when I was a kid, my parents fixed everything
they could, and in all honesty, life was much better then, and people
in many ways had more money left over at the end of the week or month.
Of course back then, people did not live to own the latest fads. I
still have a TV that I bought around 1970, and it still works great.
But now we are all faced with, and being forced into HiDef tv (which I
could care less about). That's a large part of the problem, we are
forced by greedy corporations to keep buying stuff. When MS comes out
with a new OS, they force out many of the older computers, and now
they are doing the same with our tvs, and who knows what else. I
still use Win98 and have no intention to upgrade, and I dont even like
the picture on a HDTV.
Ya, I am getting off track here, but I have a valid rant. The older I
get, the less I want to change, particularly when that change is in
most cases just to make some company wealthy, and does nothing to
benefit me as the consumer. I find the newer MS OSs just bloated, and
overly complicated with no benefits. And as I said, I like the
picture on a standard tv much better than HDTV. Unfortunately, our
younger people live to kiss the asses of these companies, because
their generation is never satisfied with anything. So, these
companies win, and us older people suffer as a result.
It's a sad state of affairs America has become......
