attached to the column with a hose clamp-like thing

 

Well, I guess I'm not through with this yet. That is an aftermarket setup just like mine.

Here's the wiring diagram that comes with it. Two items missing from the scan at the bottom.
E. Worm screw (for strap adjustment)
J. Flasher (2 or 3 prong)

 

Jim posted the schematic in Post #14. But there are several flavors of SignalStat units. Some are made to have separate turn signal bulbs, dedicated to turn function, while others are integrated with the brake light bulbs. There should be a model number on the case of the unit, something like a Model 900. If you get that model number and Google for a schematic of that model, you'll be all set. If it isn't a SignalStat brand unit, you'll have to figure out the color coding. But ultimately you need to get under the dash and trace out the wires, and make your own diagram of what's going where.

Note that model 902 and 903 are not connected to the brake light switch at all.

 

So that is a after market? well maybe they just hooked it up wrong in the first place, ,ill check the model and see about getting a wiring diag

Thanks guys this has been so much info

 

Might just be that you have a flasher as opposed to the "flashmer" that is called out in the diagram.
I'm not helping, am I?

If your power source stays hot with lights on, check the ground at the lamps.

 

Look at the wires at the end of the harness cover for the turn signal arm. See if there are 4 or 7 wires coming from the lever on the column. That will tell you if you have a 900/901/910 style, or a 902/903 style. Then use the diagrams already shown above in Ross's post #33.

 

I may be mistaken, but I don't think the author uses English as a first language... I'm guessing it's probably Chinese.

 

Sadly, it could be Made in USA and you'd still see spelling like that...

 

Lilrobo just FYI, 55 was first yr for stock TS that being said your column probably has knockouts for TS. If you wanted to upgrade to EO get one for 56. I kinda like the add-on unit.

 

i do see 900 on the TS ,, i will hunt for a wiring diagram ,, thanks

maybe this will help.

 

i found a wiring diag for the 900 it has 7 wires ,, that being said if hooked up right they( TS ) should work in all position ?? ,, i dont understand in the diagram that the gray/black goes to stop light switch ?? make you wonder why the TS has anything to do with brake lights

thanks

 

It's in post #33

When you put on (say) the left turn signal, if you had the brake on at the same time, the left rear wouldn't flash, unless you interupted the brake switch feed to that bulb. So all brake light power goes thru the TS switch, and it sends brake light only to the bulbs that aren't flashing. Because they use the same filament in the bulb for brake and turn.

I meant to ask, do your brake lights work??

 

So that a single (bright) bulb may be used in the rear. Brake lights come on when you step on the pedal and, if turning, one will flash.

Repeat ad nauseum: "grounding is critical. The lamp sockets must have a -good- ground. "
Not just a wire to the frame/bed. If the frame/bed doesn't have an electrical connection that leads to the battery's ground terminal, all bets are off.

 

yes brake lights work and rear turn work ,, so its in common with front TS
