Dan,
I use 11720 H 4858 transponder, The patient channel for aiming. It's a strong tp. Probably you need to use 3 digits for your latitude and longitude. I use 42.7, 86.2 . That makes us nearly neighbors.
Where are you , anyway, I'm on the south side of Holland and can probably come and help.
My advice is to take a small TV and receiver out to the dish with you, to lock in that true south bird. It makes the process much easier. My Streets & trips shows you near Allendale ?
The basic initial setup for a motorized system is as follows:
1. On the motor scale, set the latitude of your location.
2. On the dish elevation scale, set the elevation determined by your motor manual calculations, ( sometimes furnished by a web site calculator ) .
For example, My motor , an HH90 is set to 43 degrees, because my latitude is 42.7 degrees.
The dish elevation setting for my location is 38.4 degrees, so that's my starting point on the dish scale.
Now, with the motor "loosely " attached to the perfectly plumb mast, the entire assembly is pointed as close to true south as I can determine. The motor is snugged in place to the mast and I start up the TV and receiver. Using USALS mode, I enter my latitude and longitude into the "set location" menu area. Now the receiver knows its precise location.
I select the southernmost satellite to my position and set it up in the antenna menu screen with a strong active transponder. In my case, that in AMC3 @ 87 degrees.
The motor moved just slightly to it's 87 degrees position . Now that the reciever "thinks" it is pointed to AMC3, I have to loosen the motor mounting nuts until I can barely turn the whole assembly east and west, a tiny bit at a time, while watching the quality indicator on the receiver. When I have the best quality I can get this way, I tighten down the bolts on the motor again.
The next adjustment is to slowly change the dish elevation setting, to get even more quality. Move only 1 degree at a time, and allow time for the receiver to respond to the new location. Once you've optimized that signal , you should be done. Tighten everything down solidly .
Setup a western satellite and have the receiver go to it. The motor should go there, and your quality should be good. The same is true of eastern satellites.
