1874Re: [solectria_ev] Another NLG4 Bites the Dust?
- Feb 2, 2006Speaking of solder
Anyone tried to use the new solder with the older solder like what would be
in the Brusa charger? I assume the old stuff has lead and the new does not. I
think you have to either have some of the old solder or totally clean off
all the old solder if your going to use the new solder.
Has anyone else figured out anything different?

Take a flashlight and get a good look at the circuit board kind of in
the middle of the unit that has all the red and blue capacitors on it --
It's mounted close to another board and may be hard to see the bottom
surface. See if you can spot any black/brown discoloration around any
of the places where those capacitors are soldered to it. I'm working on
a unit now that has had a failure that burned out the circuit board on
two of these capacitors, and I'd be interested to see if yours had a
similar failure. You may also see whitish smoke deposits somewhere in
there that may indicate the source of the failure.
The good news is, the failure seems to be related to bad solder joints
and may be repairable.

before the bulk charge would have ended and everything seemed fine. Came back
and there was a distinct smell in the garage, not unlike new carpeting maybe
even overheated carpeting. I used my nose and found the smell located around
the charger. I know the smell that the NiCD batteries make as they are
charging and this was distinctly different and stronger.

overcharge. The status was zero (NO PROBLEMS) and the voltages seemed to be about
right. I allowed the charger to finish the overcharge which took another hour
and a half. Still the monitoring gave no indication of problems.

the closed container. Looking at the components nothing is terribly burned up
and my nose isn't accurate enough to tell where the problem is. All the
fuses test good. If I had to guess it is coming from one or both of the two
big transformers (? I don't know electronic names) that are connected
directly to the heat sink.
