We started these last year sometime and got distracted.... Time to assemble... Make sure the positive diode carrier is isolated from the main chassis... Notice you can have the carrier twisted far enough to shot out, make sure it is centered... My buddy at the machine shop pressed the diodes and pulley on for me already. These old round backs you need to be very careful that the 3 field wires coming in out ring are not shorted (notice the heat shrink tubing) and they are tucked back far enough that the stator does not hit them when it spins. I had to make a few adjustments as the center wire is very short on this one... The fan blades on the stator was hitting it.
