When you check the fuses, if they are glass fuses, use an ohm meter. Quite often, old glass fuses will look OK, but will have separation behind the metal end caps, and therefore be open (bad).

Even an ohmmeter won't work on glass fuses which have been "slow cooked". There will be a carbon track, the meter will read good. Just buy new fuses and make sure they fit tight in the holders.

I purchased and installed the PowerMax Boondocker converter from best converter.com. I selected the 45 amp size as that is more than ample for my 12v needs in the Trade Wind.

http://www.bestconverter.com/Powerma...rs-_c_154.html

This converter does have three battery charging. I have had no problems from over charging my battery and "cooking" it dry.

It was a relatively easy installation.

UPDATE:

Ok Leadvox and others, looks like battery drained after 1 day like you guys said. Lights worked great, even most of the instrumentation panel as well, hard to believe for a 1972!

Before i order a new converter, just wanted a heads up if i need to replace ANY of the Univox fuses to be sure? Sounds like this pos converter needs replaced so will check out the Boondocker and go from there..

Thanks

I like spending other people's money. I wouldn't bother trying to get your old converter working kinda. The new ones are much better. Get it on order.

Take delivery, and have fun installing it. It is a project requiring some thinking. Old Airstream's wiring convention is not necessarily the way the converter instructions describe it. The heart of the 12v system is the fuse box. Both the battery and the converter come into the fuse box to feed the 12v circuits to the trailer. The circuits are protected from overloads by fuses. My 66 Trade Wind had 3 12v circuits coming out of the fuse box. Study your current wiring in and out of the fuse box. Identify the function and color of each wire and write it down as well as make a diagram. Generally red is battery plus, black is 12v circuits to the trailer, white is negative or ground.

While I'm spending your money, did you get that multi meter? This is an invaluable instrument for a vintage Airstreamer.
