Please log in for more thread options Hi. I picked up one of those battery/alternater testers at Radio Shack on clearance for a few bucks. This is nothing more than a row of LED's which light depending on battery state and/or alternator output. In other words, the higher the voltage read at the test leads, the more LED's light. What I wanted to do was open it up and modify it to energize the LED's for a 2 to 5 volt range instead of the 10-14 vdc range (I think that's the right voltage range) that it was currently designed for. It has only one IC, the PA2003C. I believe by modifying the values of the resisters, and perhaps using a separate battery to supply VCC, I can get this tester to work on the lower voltage. The problem is that there's plenty of PC2003C's on the market, but I cannot find any information at all on how to use the chip. A data sheet would be nice, but just a brief description will get me by. Does anyone know anything about the PA2003C? Thanks! Denis | |||||||||||||

Please log in for more thread options Hi Denis, I found the uPA2003C made by NEC might be what you're interested in. http://www.datasheetarchive.com/datasheet.php?article=3672103 Hope this helps, Bart | |||||||||||||

Thanks very much, Bart! That's what I'm looking for. Plus, I was not aware of the archive site (being a novice) and I'm sure it will be of great use in the future. Regards, Denis Bart wrote: > > Hi. I picked up one of those battery/alternater testers at Radio Shack
