Thanks, Jim and Tojo. Gary, the wiring is to run the motor, no lights on this one.
I have the kettenkraftrad put together, and the cart, with the basic paintwork also done. I found a 1.5 volt silver oxide battery that will fit (barely) in the battery cart and tested it with the motor and all seems well there. I have the 190A3 in basic paint also, the clear coat went on after the photos.
Here is a photo of a F8 type hooked to the cart.
