Hi Tom.

A similar question came up just a couple of weeks ago concerning T2X
wiring.  While I had my Ham IV rotator down recently to service it, I
didn't pay much attention to the wire colors except to note that after
all these years, they were pretty faded.  I did a little searching on
the web and here's what I came up with...

Norm's Rotor service web site states the following:

"The colors vary from manufacturer to manufacturer. But it really
doesn't make any difference, as long as you make sure that you're
connecting terminal 1 on the rotor to terminal 1 on the control box,
terminal 2 to terminal 2, and so on. Also, on the HAM series and T2X
rotors, you need to be aware that the heavy wires must go to terminals 1
and 2. Norm uses this color code for CDE/Telex/Hy-gain rotors."

If I understood correctly, he has no terminal strip and he needs to know which wires go to what terminal from the inside. I chose to use the pigtail instead of the terminal strip.

By far the easiest is to call Hy-Gain. They can give you and answer and will likely send you a wiring diagram. I recently rebuilt a Ham IV. The IV and V are identical inside. Only the control box is different. BTW I was able to purchase the bearings for less than half the price of the same size balls at the local hardware store.

1. black #18 gauge 2. white #18 gauge 3. green #22 gauge 4. blue #22 gauge

5. orange #22 gauge 6. yellow #22 gauge 7. brown #22 gauge 8. red #22 gauge is the color

Ham IV manual here:

CD-45II manual shows actual wire colors used in the rotator on page 14.
They are a match to those noted in Norm's comments, above:

Let us know if this works for you.

I am repairing a Ham 3 that has a missing terminal strip on the
bottom.  I can't find the wiring color codes for terminals 3-8.  I
have 1 and 2 working the brake OK.  I would appreciate any info on the
remaining wire colors to their respective terminal strip numbers.
