Sorry to hear about your injury. The bike is cool, how many horsepower does the diesel put out?, a torque monster for sure. Once you get the gearing correct you’ll be motorcrossing for sure.
Dad 36’ rumble coupe, plate is Vermont 1945. I couldn’t find any side views of the car in a shoebox full of b&w photos, so I don’t know if it was a 3 or 5 window. I know I was about a year old when it was forced off a Vermont mountain road and rolled down a hill, no serious injuries occurred...
The batteries in your phone only require 5 volts to charge, the batteries in your devices are 3.7 to 3.85 volts. 6 volts are plenty to charge your phone you just need to get the polarity correct.
I converted a dollar store lighter type charger by switching the inputs.

Or you can just remove the guts and mount it on a piece of plastic and hook + to + and - to -. Your typical USB wall charger puts out 5 volts.
I hope that doesn’t happen my local NAPA has go to flathead guy, he’ll spend a lot of time with me looking up parts in old books rather than using the computer.
