1975 Argosy wiring schematic

[argosy75]

I need a wiring schematic for 1975 Argosy. My running lights don't work anymore. I took them off. checked all wires. malfunction in green wire for running lights. It seems to splice off into a red wire after it enters trailer. Any help finding where the two colored wires meet would be greatly appreciated! URGENT!!!!!! THANK YOU VERY MUCH!!!!!!

You never really know what a PO has done to make things work. Best thing to do is check grounds and use a test light or meter on the one wire that is used for these. lights. They are in series like a string of Christmas lights. One light is out and all are out. If you havepower at one light it is most likely bad grounds. Good luck!

There is a connector block where the TV - trailer cable enters the trailer on the interior. I would guess it will be near the front of the trailer on all of them (Why have a 30 foot cable???). Find the connector that goes to the clearance lights and be sure you have continuity to that point. (I use a continuity light and a long wire to connect the trailer connector (outside) to the block of connections (inside). If there is no continuity there, the problem is the cable or the trailer connector. If there is continuity to the interior of the trailer, use the continuity tester to go from the connector block to one of the clearance lights. If there is continuity there, check the ground. The only way they can all be off is if the supply wire is not getting current or is shorted out. Each light has its own ground through a mounting screw. Be careful when pulling on the lights as they seem to be connected to the supply wire with bullet connectors which can pull apart leaving you with the task of taking the interior apart to get at the wires. :-(

Thank you for your input. I rechecked the trailer plug. There was a loose wire for the running lights, also, wires in the trailer frame by the hitch needed to be cleaned and reconnected. The fuse in the truck needed replacing too. After I did all this, the running lights worked. I'm now in the process of putting all new LED lights in the front and back.

I had a few years of simple cleaning and replacement of plugs and cables until last summer. The running lights on my 71 Argosy 26 wouldn't work until I hooked a jumper wire from the big cable that hooks to the tow vehicle up inside the trailer and tapped into the running light wire behind the overhead cabinet. This was only to get it to the dealer where other repairs were scheduled. I was lucky enough to meet a service tech in Pittsburgh who had worked on the Argosy line the year mine was built and was full of priceless information and a whole box full of new (old style) parts he sold for a song.
The wire junction is just under the front of the trailer INSIDE the left frame where it traps dirt, ect. and becomes a prime point of failure. The only access to this would be through the belly pan or floor under the couch. Either way means a hole big enough to work through and a good guess at its exact positioning. I chose the floor and made a aluminum plate cover so I could have easy access in the future. I love my new LED lights too they are so much more trouble free (and brighter too).

Which LED's are you using? I've just strarted investigating the possiblities of this and I found this site:
Super Bright LEDs - Car Bulbs
It looks as if these require a load resistor, at least for the signal lights. Not insurmaountable, but I'd prefer a direct replacement. Thanks.


btw: there are lots of other LED applicaion on that site. home, etc. very interesting.

I thought this site looked interesting for direct replacements:
led truck lights, led trailer lights, led clearance lights, led marker lights

Happy to hear the clearance lights are alive and well.

I found the marker lights both amber and red at two different truck stops on the interstate nearby. The local tractor supply store also carries them but not usually many in stock at the same time. I found some direct replacement bulbs for the stop and tail lights through a marine supply store, I believe it was West Marine. A heavy duty flasher for turn signals may not be nessary as the LEDs use much less power.

Thanks for the info on the other sites. I ordered the bulbs from Vintage Trailer Supply - Vintage travel trailer parts and supplies!.
