I have a 1998 Safari Class C built on a Ford frame. I've been having electrical problems problems for a while. I'm getting no power from my batteries and they won't charge. Everything works when I'm plugged in. I don't appear to be getting any power to and from my house batteries which are charged to 12.6 and brand new. When tracking a main wire from my alternator I found this object. It appears to have a large wire coming from the main bundle and two thinner wires going back to the bundle.
Can anyone identify what this might be and could it be responsible for my electrical problems. I'm at a loss at this point. Attached are several pictures I crawled under the rig and took. This is the unit in question.

Re: Can anyone identify this
Are you sure those are wires coming and going? It reminds me of a vacuum reservoir.

Re: Can anyone identify this
I have no idea what it is. I'm wondering if the two light wires go to the battery isolator solenoid. It took a minute for your picture to show up. The thing you showed is rather round. The one in my pictures, it's hard to take them under the vehicle, is elongated and probably a foot long. I haven't tried to open it up yet. Kind of scared to.
Re: Can anyone identify this
Sure looks like a vacuum reservoir to me as well.
Should be able to distinguish between vacuum lines and large-gauge wire pretty easily.
And, the vacuum line would be coming off the engine's intake manifold on a gasoline engine.

Re: Can anyone identify this
Without a better picture of the actual connection area, I'm going to agree with the previous posters in that it looks like a vacuum chamber of some nature. There's a somewhat simple way to tell - take a good look at the connections to the top of it - if it looks like rubber hose/tubing around the whole connection, I'd lean towards it being a vacuum chamber/reservoir of some sort. The large hose may be the input and the two joined smaller ones go to other areas/items on your rig. * Correction * I just went online and googled for a Ford RV Vacuum reservoir, and this is the third or fourth picture of one shown for the F53 Chassis.

Re: Can anyone identify this
The more pictures I see of the how the tubing is connected, the more I'm sure it's a vacuum reservoir. Those aren't wires. You're electrical problems are not related to this canister. If your air conditioner vents stop working and all the air starts coming out of the defrost outlets, come back and visit this piece.
I updated the image in my earlier post for show an elongated tank.

Re: Can anyone identify this
That's it. The image you posted looks identical, but why the light colored wires? But thanks for the information. Old Safaris can be a nightmare.
Re: Can anyone identify this
Those aren't wires. They're plastic tubes. Somewhere, they're connected to the damper motors that control the heater/air conditioner outlets. The selector switch on the dash directs the air down to the floor, through the air conditioner vents or through the defrost vents. If there is no vacuum, the system defaults to the most important thing - defrosting the windshield. Often, while you're going up hill, you'll loose vacuum. There's check valve between the manifold and the reservoir tank to try to keep enough vacuum the system won't default to defrost mode. Lots of times my check valve won't hold and air stops coming out of the a/c vents and starts blowing out the defrost vents till I get over the hill and there's a vacuum in the manifold again. Sometimes, those small tubes break and let air rush in dropping the vacuum to nothing. Even rarer, a diaphragm in one of the damper motors will leak. If the tubing leaks, find a good piece of neoprene vacuum tubing the same ID as the plastic tubing's OD and slip it over the broken ends. If the diaphragm leaks, you'll need a new one.

Re: Can anyone identify this
I appreciate your information, but there are two wires coming out of the unit. They can be seen in the very first picture I posted. I've squeezed them and they don't seem to be tubes. The other one that enters the unit may be a vacuum line. I'll go under and check that again as I have to re-bolt the unit back in. I pulled it loose yesterday to get a better look. My heating-A/C unit seems to be blowing correctly.
I was confused so I posted here. There is very little available information on these RVs.
