1974 Airstream Sovereign right side exterior lights

Hey everyone,

I've been messing around with my newly acquired 1974 Airstream 31'. Pretty much all interior lights are working properly, but once I get outside, I'm running into problems.

When the trailer is connected to my truck, the LEFT blinker works...but no running lights on the right side, left side, or in front. The right side blinker doesn't work at all.

I've checked all the bulbs to make sure they aren't burnt out... looked at my "glass" fuse panel, and they all appear to be okay... and I cleaned terminals and the bulb itself.

Any ideas??

The cord that the umbilical connects to your TV with is the driver for the turn signals and the running lights.

The green wire controls the running lights on both sides. The brown wire connects to the right turn and stop.

So, a look at your umbilical system would seem to be in order.

Sometimes, just reversing the umbilical cord can fix things (flip the connectors end to end).

Good luck!

ps: some years (and I think `74 is one of them) use different connections to the umbilical plug. There`s a hint

If it's to be, it's up to me.

If your trailer plug has the original wiring configuration. The colors in the UCord may even be different. It won't match the TV.
I would suggest using a battery charger to ID each of the circuits. Connect the black lead of the charger to a clean spot on the frame. Clip a common screw driver to the red lead, then insert the screwdriver tip into each of the connections on the trailer plug. Make a note of what lights come on.
Once you have each circuit ID'd. Connect them as follows.
Connect the function of each wire to the colors listed below. A new plug may be in order for the UCord. The new plug will have colors on each of the terminating points. Again, the colors in the UCord may not match the function, connect them according to function.

Black= charge line
White= common/ground
Green= tail/marker lights
Red= left turn
Brown= right turn
Blue= brake controller
The center pin is an option for backup lights.

Had somewhat of the same problem with our 75. Try disconnecting the umbilical cord from the coach where it plugs in and cleaning the pins and the female ends of the cord. This area can build up corrosion after a period of time.
Also, if you have a battery charger (when you have the cord disconnected) you can attach a wire or anything that will give you a positive connection while grounded then go pin by pin ( on the male connectors) to check the inside distribution thru the panel located under your gaucho. Takes 2 people to do this.
This will tell you if the cause is beyond the umbilical connection and in the wiring of the coach.
Cost me a hundred bucks to watch the guys at my local shop do this. Turned out that for me, they just cleaned the pins and the female receptacles and all worked. But at least now I know how to troubleshoot the hookup to the inside redistribution panel.
Hope all goes well!
