hey guys...Yesterday, I was charging my Yaesu VX-5r in the car with a
makeshift charger, and the hot lead that was connected to the center
pin on the radio grounded out against the radio's case....and now the
radio will power up, but will not charge.

My question is: has anybody ever experienced this on this or a similar
radio, and have any idea what component in there got toasted? I opened
the radio up and saw no visable damage, but the components are barely
visable themselves...I read the schematic, but it's more of a
block-diagram, and I couldn't get much out of it.

I know this was a stupid and careless mistake....but if anybody has
any suggestions, they would be appreciated! (or suggestions on how to
build a charger for LiOn batteries!)

Another test would be to take the battery out, and power the radio
from the supplied wall cube. If it operates/ powers up, then most of
the circuit is working.. if not then there is probably a fuse or
resistor used as a fuse blown.

Yaesu does offer an external drop-in charger for this radio, should
you wish to purchase one.

I just tried, and the radio won't power up off of the supplied power
supply at all...also, when I put a charged battery on the radio, it
reads an extremely low voltage on the internal voltmeter, and the
radio acts like it's going dead (backlight won't turn off, only low
power TX)...so it is very possible a risistor got hit....I didn't see
any fuses...but I didn't take the radio all the way apart
yet...thx..IAN
