Its going to be METER then disconnect. There are a lot of rules to follow doing this. In fact you probably dont need disconnect there at all,, the panel in the house can be the disconnect depending on what your goals are. Here is a place to start. Then you can come back for some more explanations of details later. You will need to look thru the site to find what you are looking for. I am sure its in there somewhere. http://www.homewiringandmore.com/index.html

ouch!! There are some major problems. Let us know what you corrected (and how) and give us some more info. Like what makes the meter wired wrong? How is it wired now? How high is your weatherhead? Where is the point of attachment? How high are the lines coming in off of the ground. #4 is de-ox missing. This is required on aluminim wire. It coats the wire at the termination points.#1 is ground loop missing. Could it be that you did not bond your water meter? You need to take a #4 copper (for 200 amp service ) to the water line and clamp it before and after the meter.#8 Bond bushing Required. Is it a metalic raceway between the meter and the panel? If so, you will need grounding bushings on both sides. I am not sure on #9, but if there is a fitting that screws into another fitting, you do not need a locknut between them.
Hope this helps
Brian

1.weatherhead is about 8-10"from top of pole,thats done.
2. meter is wired right now.
3.wires from their pole(elec.co.)are to go to top of my pole and down to 100 amp disconnect then back to meter,up pole,to 50' overhead wire to cabin.
4.don`t have water meter,they said to ground pole and cabin.
5.1-1/4" threaded pipe between 100 amp disconnect and meter.
6.whats a grounding bushing?

What matters is the height from grade to any point of the overhead service is not under 8'. It is 10' if it goes across a driveway
I will need to check on the having two risers. I don't think you are allowed to have two of them in the same location but I would need to check.
Why is the disconect before the meter? I have never seen this before. Usually, when you install a disconect,anything after this disconect is considered sub panels, therefore requiring a 4-wire system. But since it has not passed through the meter yet, it maybe considered the power co. equipment. That is a new one on me.
Grounding bushings are big insulated bushings with lugs and a screw on the side of them. You need to thread this on the connectors and tighten down the screw on the side of it. You then need to take a wire from each of this to your grounds.
Since you was cited for no bonding screw, You should ask where this needs to be at? Usually it is at the first point of disconect. But again, the disconect is before the meter. If you only have three wires going into your meter can, you must install the screw into the panel. I don't agree with this disconect before the meter. It can cause a problem with bonding your grounding and grounded wires.
Hope this helps

Bwetzel, A quick change on your overhead heights according to 2002 NEC 225.18---10 feet above ground where there are only pedestrians. 12 feet above driveways. I also agree with you that I also have never heard of a disconnect before the meter. Most meters have no way of isolating the neutral from being bonded to the can to accomodate a 4 wire system. I guess maybe I'm (or we) are missing something.

Joren,
Thanks for the update. I thought that they have changed,but Michigan has not adopted 2002 yet.(Nor have I taken my update class either)
If it was to be wired to the NEC, I would think that it would have to be 4-wire through the meter also. Like you said, I have never seen a meter setup like this.
