"My old charger went belly up so I'm in the market for a new one."
Olezippi,
When my battery charger went belly up about 10 years ago I did a little online research and found that a failed diode is often the culprit and I found a video showing exactly how to replace the diode. So I got an inexpensive bag of 3 alternator diodes on Ebay and installed one of them. That fixed the battery charger for way less than the sales tax alone on a new one, and the job took only a few minutes. That old battery charger is a really nice made in USA tool that was definitely worth saving. It's still going strong too.
