I have an early 1990 with the Detroit diesel. I've been looking for the schematics for the battery, isolator and solenoid area but haven't found one for my year. I'm missing the number 2 of 3 manual that has what I'm looking for. Thanks for the help
Have you tried looking in the Forum Library, in the Schematics folder? That folder should contain most if not all of the electrical diagrams that have been uploaded by Forum members.

Missing a manual can be tuff. I have 1991 U300 with a Detroit and I only have 2 three ring binders. I've never been aware that I'm missing a third and I've owned this coach for 23 years. Could be they just went from 3 smaller binders to 2 larger ones.
From what I can tell, Foretravel doesn't have specific drawings for each year. It appears they make new drawings when there are changes. Fortunately Foretravel seems to have methods of doing things and they don't change a lot year to year unless there are major feature changes. The best gauge is knowing your build date (on the placard next to drivers seat) and the the date and description of the schematic. There are two spaces in the title blocks with EN and CN. I'm guessing those are the "cut-in coach build number" and "end coach build number". My build number is 3861; I'm guessing yours would be around 200 lower than mine.
Here are the schematics for my coach (model year 1991, but built in Dec 1990) which I think will be very close to what yours it (1990). I also include a photo of my 12 volt panel in the basement.
You might notice a date of 1992 on a couple of the drawings. I think this is because my coach was owned by the Motorcade club in its first couple of years and then I'm guessing the manual was put together when it was sold to a regular customer. It came with fabrics and counter tops seen on 1993 models. My understanding is the club would "test" the new fabrics/colors with customers at rallies to see how they liked them.
Thanks John Fitz. These are a few that I didn't find while searching in the schematics. I'll jump back on this this weekend.
Chuck & Jeannie, I spent hours looking through them and found some helpful schematics.
