My fault....since the charger that came with my Yaesu VX-1R HT ham radio died a few years back, I have been using a charger that was not rated for the job (correct charger output: 6VDC, 500mA, used: 9VDC, 200mA). If done in moderation, this did charge the battery, however, this time I overdid it and it is no longer functioning (no power, even when on the charger). So...I clearly must have overloaded the regulator IC or some such. Question: in general terms, is it worth repairing or do I chalk it up to stupidity? Disparaging comments welcome. Thanks!

General rule:
You can fudge the amperage, but the volts must match.

As with anything, you can repair it, but the availability and cost of the components can add up quickly.

I would bet you fried a voltage regulator. S/B an easy fix if the component is available and you have the skills.

Joe,

That's an excellent tip and good advice. Thanks. I did dissemble the radio, and was able to re-assemble without leaving any extra fasteners, but there was no smoking gun or diode, to be had. Skills: looking at the radio's circuit diagram is kinda like a monkey staring at the back of a watch - not really getting the concept. I know why I'm a M.E. not an E.E.. Thanks for you time.

The components don't need to smoke to go bad. If you have a decent quality camera that can do macro, I could possibly identify the component(s) you need to check. You would also need a multi-meter.
