Fuse Panel 1964 Globetrotter

[tmeagle1]

Can anyone tell me what the function of this box is and if I were to ever decide to replace it what is the best replacement? I will post a picture of the front and side where wiring feeds the interior fuses. Thanks for the feedback. The first fuse is currently not giving me power to the front interior lights, I notice where the wire is connected the metal piece is loose just above where the fuse connects, will this cause some lights not to work? If so, would it fix the problem if I moved the two wires to the middle slot? Thanks.

I could stab at a guess.

Could it be a manuel converter?
Switch set at battery for 12vdc from battery when not plugged into shore power. Switch set to shore power when plugged into shore power would take 120vac and covert to 12vdc.

From what I've discovered this is exactly what you stated Geocamper. It's two switches to turn off battery power when using shore power. The bottom two wires are coming from a converter and the top two wires are twelve volt. Each fuse slot needs both wires to operate. I hooked up the twelve volt wire to the top of the middle fuse and the bottom wire to the bottom of the middle fuse, put the fuse in it and the lights worked. I think it's just a complicated fuse panel box and will eventually we'll replace it since it is original to the '64. Thanks for taking a stab at it. All is well, I have 12volt lighting where in the Airstream.

That is an early type of power converter that uses a transformer to run the lights on 12 volts AC and the fan and pump on 18 volts AC. It is similar to a modern "converter" but does not charge the battery. The switches, as marked, connect the various loads either to the transformer or to battery power.

Modern replacements are designed to charge the battery and require a certain amount of rewiring. Replacement may not be necessary.

You may be able to squeeze the blades of the fuse holder together to get it to work. Disconnect the battery and the shore power cord first. I believe that the original fuses were a somewhat larger physical size that is now difficult to find.

Thanks for the infomation.
