      I have a model “B” RBM ser# 24767 with a ignition problem. It has a magneto ignition. My problem relates to the second coil . Looking at the top of the mag plate I am defining the the coil on the right as the first coil ( spark plug connected to this coil) I can measure the resistance of the first coil and see the wire going to the second coil but can not see a second terminal on the second coil.
      I assume the second coil should be grounded. I get infinite resistance on the second coil. Does someone have a schematic diagram of this mag , or know where the second terminal is located.?

      Second question: The name plate that mounts on the top of the gas tank. Is it mounted so you read it from the front of the engine or the back ?

      Thanks

      John
