Battery compartment redo

[John & Barb Ely]

Bob Howald:
I am recalling soldering lore from many eons ago when I was an AC tech, and
I think you may want to consider looking at those new cable ends.
In order for a solder joint to stick, ALL components must be above the
melting point of the solder. If not, you get a cold solder joint. I may
have misread but it sounds as if you stuck cold cable into hot
solder. Almost by definition, the solder in direct contact with the cable
as it slipped into that pool would have dropped below its melting
point. The chances are pretty good that your copper ends stuck only
partially on the 4 aught cable and will eventually break, in the mean time
providing a nice spot for hidden corrosion. I recommend that you reheat
those joints, applying the heat to the cable. It will be a whole lot
easier to do that now and avoid the frustration a year from now of trying
to figure out why your batteries aren't charging, etc.
