Hi,

This won’t be a consolation but. I had and have got new the 5500

It lasted me 10 years and seized. All for the sake of some drainage holes in the casings.

I stripped it but was so far gone.

I had such a great love I bought it again. Still no drainage holes, it has now!

I take it down in Late October clean it and apply grease.

Ring a local Sat TV Guy to take it down and put back when you have Bench tested.

 I've done a few more diagnostics to try and determine why my AZ rotor suddenly stopped working. Here is what I've learned:

Voltage between terminals 4 & 6 and 5 &6 is 30 volts with the switch activated so that suggests voltage should be getting to the rotor from the control box.

Checking resistance at the controller terminals 4 to 5 shows 8 ohms as it should There is no resistance shown between terminals 4 to 6 or 5 to 6 and I believe that should shw 4 ohms.

So now I'm stumped. Could the problem be in the rotor connector or in the rotor itself? Any thoughts from the group. I'd like to get this repaired before the snow flies!
