Best of luck.

They do not publish one for the camper part but the chassis manufacturer does have one (you might have to buy it though).

I doubt these will help, but you might be able to figure out what you need.

Adobe couldn't open any of your files!

Except the modified one!

I switched to 9volt batteries and have a diagram to wire two of them in series but I can't identify the wires inside the MH!

I have run into this before. You need to update your "Explorer" and Adobe Reader to the latest versions.
You mean 6 volt, right?

dunk05 - Is there something specifically you are looking for or wanting to do? I may have something for you or be able to answer some questions.

I just want to install two 6volt batteries correctly! The battery cables from the MH aren't marked and they are all red!

I think a little more information will help. This usually takes an in-person approach to truly find the correct wiring configuration. If you are unsure how to check with 100% accuracy and your coach isn't capable of being moved then call a mobile RV tech and have them do it.

1. Are the old batteries still connected correctly? Then its easy to ID the neg and pos based on battery terminal.

2. Is it possible to follow the cables? A cable leading to the chassis is negative. The negative battery cable usually doesn't go too far before connecting to the frame.

3. If there are no existing batteries to use as a map and no way to follow the wires, then use your multimeter and check for continuity. Read through your digital multimeter's instructions on how to check for continuity.

Not that you asked, but whatever you do, please don't do the backyard mechanic's "SPARK" test.

Once you ID which is which, make sure to label them correctly and take pictures that you can store in the coach for future reference.

OK I found the ground wire and put all three red wires and one with a fuse in it to the plus terminal of the battery! The 12 volt system works now but the fan on the converter box now runs all the time!
