You're on the right track. You'll soon find what you need.
I cheat when I connect the jumper wires between the potentiometer and small contacts on the rear side of the Mega's board mounted pot.
They're soldered of course. But I use solid 14 gauge copper wire. A long length. The end of which is manipulated by a third-hand alligator clipped to the wire. I then solder the solid wire to the pin.
Then I trim the length of the solid copper wire to length. I connected 20 gauge wire to the solid wire. A piece of 3/16" 3-to-1 heat-shrink gets slipped over the wire and down to the Mega's pot on the board. Then I do the 2nd one. Both wires rises vertically and I GOOP then to the face of the Mega's case for strain relief. The wires of course then continue on to the potentiometer's tabs. Turning the knob clockwise raises the voltage of the Mega. In reality with the pot, the resistance is decreasing as I go clockwise. Clockwise to increase voltage.
For the timer eBay INTERMATIC® SPRING WOUND TIMER. They are more reliable than the other kinds, and a glance of the knob pointer tells you where you are at.
Criminy! I took a break and came back to a Black & Decker charger sitting on my desk! Lightweight. I'm afraid this one is an "automatic goner" right off the bat. They buff the numbers off the IC's and I'm not into wave soldering. The transformer jobs I can repair more manual operation. The lightweight ones are scrap. Ooooooo we plugs it in, and ALL the lights come on. All 7-digits of the volts and amps. Reverse polarity, temperature, all charging levels. An expensive Christmas tree ornament.
Smart. Real Smart.
