Is there any chance someone could direct me to a diagram for wiring turn signals. They used to work but I have the feeling something got disconnected. I've uploaded some pictures for your viewing pleasure... by the way, I've taken the truck out a few times on the road now, it feels great!







I know they are just random pictures but maybe somebody could either direct me to a diagram or pick something out? Thanks!

 

Hey Max, I would trace the wires back from turn signals to be sure which connections to look at, also put a meter on those glass fuses to be sure one hasnt gone bad. On these old trucks sometimes if you have one turn bulb go out it can affect part or all of the circuit...
Get you meter out and start tracking, good luck

Thanks that's a good idea!

 

What is the fuse protecting with a hot wire - Red going in but nothing coming out?
Oh - The underside of your instrument panel looks like it is going to start leaking smoke at and second.

 

Uhhh, maybe the bare unconnected wires hanging off the flasher might have something to do with them not working? Mmm! Spaggetti, multicolored at that, makes me hungry. Wiring is a lot easier to trouble shoot if it's run neatly and bundled by function.

 

Well I shouldn't exactly start by randomly connecting things together right... I've gotta find some sort of diagram for this.

 

early systems are very basic.
rough diagram.

 

How many wires do you have coming out of the switch?

 

Here's the basic wiring diagram for the type of turn signal system you have. You have to determint if you have the five wire or seven wire system. With the five wire switch you need two sets of rear lights, one for turn signals, one for brakes. With the seven wire switch you only need one set of rear lights because the switch has an internal switch that opens the brake circuits, see the bottom animation:

 

Bob, the only thing I might question is that your diagrams look like they are for a neg ground system? The power would have to come from the neg side if it is a 6V pos ground truck (pre 1956) that has not been converted to 12V neg ground.

 

Thanks, I changed diagrams to be more generic

 

Good job by the way. Those diagrams need to be placed in the articles and specs section. Meanwhile I have saved a copy for myself, you never know when you might need them. Thanks

 

In his picture, it appears that his flasher plug has 3 leads on it. The black wire should be going up to the switch, and the red wire with half the fuse holder should be coming from switched power to the flasher. The two white ones are not connected at all and this is certainly going to be a problem.

I made this diagram when I rewired my truck. It is for the "Everlasting" type switch, but will show you the hook ups in the 7 wire system with three wire flashers, and I think is the same as Bob's 900 series drawing. The colors I show coming out if the switch are the correct colors for that switch but you can see later on down the line I may have switched to a different color. I'm providing this for signal flow.

Here ya go:



If you have trouble reading it go to http://members.***.net/japeterson/49...g_Wiring.ppt#2 There are two like this, one shows all my extra toys and one is generic - you will see the difference!

Or if you like, just send me a PM with your real e-mail address and I'll send you the full size drawing in Power Point.
Good luck

 

I have left a wiring diagram for turn signals in my gallery. If you need it bigger to read I can send you a PDF

Thank you everyone for your help, I'm going outside to take a look right now!
