If you are sure all is well with your pummer, then go ahead and snug the
battery pack up to the back of the PCB. Solder it in and snip the leads.

TTACHING
THE
SOLAR
CELL
Pull the battery pack off, so it’s easier to solder the solar cell wires to the
PCB. This is pretty straightforward if you remember to solder red to “+”
and black to “–“.
Strip off a bit of insulation from the end of the wire by firmly pinching and
pulling it off between your thumbnail and index finger. Or use a proper
wire-stripping tool if you wish (but it’s not as much fun). Solder the red wire
to the PCB pad “Solar +”, and the black to the square pad next to it.
Do the same on the solar-cell end of the wire, red to the oval pad, and
black to the rectangle pad.
If all is well, when you hold the solar cell up to the light, the pummer will
stop working (and start recharging). Cover it with your hand, and it should
kick back to life!
