Adding Roof Air & New Voltage Regulator to Our 1976 24 T

Holiday Greetings!

Just took possession of our 1976 Argosy in amazing condition. Want to add roof air, but there seem to be many opinions on where to place it (front vent over kitchen, rear vent over twin beds or cut a new whole between them in the roof)! Please let us know which option you have chosen, and if you know where Airstream probably placed the wiring harness (and drain?) in this particular trailer.

If you DO recommend cutting a new whole, how much does that procedure add to the air installation at a reputable retailer (such as an Airstream dealer)?

Finally, what are your recommendations regarding replacing the original voltage regulator/converter? It's making a loud humming noise...

Thanks in advance for assistance!!!

There is only one place to install a roof AC.

The wiring is already in the roof.

I will find out the location of the wiring for you and so advise you.

The hum in the converter simply means that the transformer plates are loose.

You can repot the transformer or replace the converter with a new style. New style converters are solid state, so the only noise they make is if and when the fan comes on, which is a cooling fan.

I have only one rule... use holes that are already there! If you have work on skin replacement u will find that the roof vents are not just a hole rather a complex working or many components.. There are structual members between the skins, these ac units are heavy and wind resistance places futher stress. If you simply cut a hole in the roof u may do damage to part(s) that are important, not to mention you will need to add many structual members! besides less holes in the roof is better than more! Andy is also correct many trailers are prewired!

Take the transformer out of the univolt.

Get a pint or quart of high temp paint.

Put the transformer in a small container, and pour the paint over the transformer.

Gently shake the container so as to remove any bubbles that may form, or invert the transformer, or both, several times.

Let the transformer soak, for at least a day, if you can.

Remove the transformer, let it drip dry, then reinstall it in the univolt.

The noise will be gone.

Loose laminations cause the hum, since they will be ever so slightly moving when power is applied.

You will fill the voids between the laminations with the pint.

Or, get some cheap earplugs.

Andy
