Got a Beaver?

Recently I ran across a 1984 40' Beaver Diesel (Cummins) MH. The MH is sitting and in need of -- well, lets say - It is in need of someone crazy enough to buy a 1984 MH that has been sitting the last 5 years.

I haven't yet decided if I am that person, but I am seeking some info. I have only seen pics of the unit, but it is located less than 50 miles from me, so I will be seeing it in person soon.

According to the owner "The toggle switch will not shift out of neutral" is this a normal problem with these units? I realize it can be as simple as a switch of a wiring nightmare. At this stage, I am not seeking info on how to "fix" the issued, but more on if anyone has heard or had this problem. The owner also stated the alternator will not keep the batteries charged. That is a no brainer, alternator/regulator/wiring.

Anyway, anyone have any info and/or experience on a 1984 40' Beaver MH how about sharing it.

Any idea what this " toggle switch " is to control ?

If he says the alt won't charge the batteries, has he been running the engine?
If he is jump starting the rig and just leaving it run, it would take days for the alt to build up any charge 5 year dead batteries.
If the toggle is for transmission control , an Allison trans controller won't do a thing without good battery voltage.
Alternators , unlike generators, require power to make power, if you spin a 12v generator , it will produce 12v+ power. If you spin an alternator attached to a dead battery ( say 7v of power in the battery) you would get 8.5>9 volts out of the alt. the alt windings have to be energized in order to function properly; the higher the winding power the higher the alt output.

I have a 1991 Beaver Marquis. It hasn't happened to me, but the previous owner says it sometimes sticks in or out of gear. Crawl under, move the shift lever manually and grease it.

Sounds like a really great restoration project. Probably no money to be made in restoration but is really satisfying to look back at the "stage" pictures later.

Hope you have lots of fun and patience.

I would look closely for signs of rot in the walls and ceiling first. If I saw much that could not be fixed easily/quickly I'd loose interest completely. That kind of trouble sends more coaches to the bone yard than all other type problems combined.

Once past that inspection, I'm game for about anything required as long as the price is right?
