Would it harm the generator if the car was run with a 6 volt battery that has been sitting for over a year. If I can crank start the engine would the battery recharge?
I am having my 1925 roadster brought home on a flatbed by an auto mover company. Since the car isn't running I assume that he will have to use a winch to get it on the truck. Where is the best place to hook it up. Other precaution/advice?
I probably over worry about stuff.
You should ground the generator output until such time that you have a good battery on board.
Since this is a 1925 with a radiator apron, I would hook two tow straps high on the front spring rather than hooking to the front axle when winching. Depending on the state of the wishbone ball, pulling low on the axle could cause the ball to pop out while dragging the car up the ramp.
As you are in the north, I would not try to jump or recharge the battery as one or more cells might be frozen if the car is stored in an unheated place. As noted above, ground the generator and keep the car's frozen battery out of the circuit if attempting to start the car.
