I am rewiring my 1948 Cub and I have questions about the 4-position switch. 1)Does anyone have a schematic that includes the functionality of the multi-throw switch? It seems that 2 positions do not connect any of the 4 terminals. 2)The coil from terminal 3 to terminal 4(?) broke. What does it do? What can I replace it with? 3)I presume the other "coil" is the field resistor for the charging circuit. How is that connected in the circuit. One end is connected to the switch housing. ??? Thanks.

The link below will take you to cub manuals including wiring diagrams. The 4 positions on the light switch are L (low charge), H (high charge), D (dim lights), B (bright lights). The broken coil is a resister that was switched into the head light circuit for the dim lights. The charge was controlled by the flat resister. normally the field circuit current flows through it to ground. When you turn the switch to H, D, or B, a ground is applied directly to the terminal where the wire is attached to the resister, this raises the charge rated of the generator.
