Thanks for all the replies on my 5500 rotor problem! I had some time
tonite
to work on it and here's what I got. On both a1 a3, and e1 e3 pairs I'm
reading only 1.0 volts. Between a2 a3 , and e2 e3 pairs I see only .5
volts

Jeff, KB2M,
I am sending the schematic for the G-5500 separately.
Disconnect Azimuth and Elevation wires 1, 2, and 3 from the Control box.
Check the resistance across the 1 and 3 leads. It should be 500 ohms.
Check the resistance across the 1 and 2 leads.
It should be between 0 and 500 ohms and
Hi Jeff,
I had an indication problem on my 5500 many years ago
I opened the rotor and discovered that there was a cold solder joint
on of the pot contacts...a proper solder joint solved the
problem...an easy one to check first..
I'm having a problem with my 5500 after a
Hi Jeff, KB2M
I have sent to you the schematic diagram for the G5500 but the message
bounced back to me because your @comcast.net don't match with my
@tin.it
By the way and first of all check if you have 5 volt DC between studs
A1 and A3 and between studs E1 and E3 on the rear of control box.

If you have the paper manual, you have the schematic. LINK to Electronic
version provided above.
Fairly straight forward,
Bill,
Start by checking the connections in the shack at the controller. If they
are good, then disconnect lines 1, 2, and 3 on the elevation side and check
the _cables_ with an ohm meter. You should read 500 ohms between 1 and 3,
and something intermediate between 1 and 2, and between 2 and 3.
