Rusty "that thing" is the 70's version of MSD, without the "M" In other words it's a breaker points triggered CD ignition. The reason the weird wiring going to the coil, is that you disconnected the coil power feed, the breaker points, and transferred them to the outer circuit board. This fed the points trigger and the power to the box. The two boards then routed the output of the box to the coil
'Just like MSD' there is no DC power to the coil. The box feeds a pulse..........sort of like an electronic photoflash.........to the coil
Sometimes you have to move the timing light pickup "up and down" the wire, or turn the pickup around the other way
Knight was a kit name for Allied radio.........similar to Heathkit. That box was either Delta or the other popular brand CD I'll have to do some "recollectin" on that
Here ya go............"Delta Mark Ten"
