Default help- CDE H3 rotor + controller


"amdx" wrote in message
...
I bought a rotor and controller at a hamfest.
It is a Cornel Dublier Electronics H3/CD44 Series 2.
The position indicator doesn't move with rotation,
the indicator needle is almost full scale and can be moved
with the calibration adjustment.
I suspect the problem is in the rotor.
I need a description of operation, to try and troubleshoot the unit.
The function of the 8 connections would help.


I have recently found that terminals 3 and 7 are a 500 ohm pot in the
rotor, don't yet know which is the wiper. Also 4 and 8 are the motor
capacitor.

A schematic would be even better.

Thanks, Mike
