The resurrection of a junkyard XS1100.
 
Well it's finally about done, mechanically sound now and running perfect with 62xxx miles on it. I now need only complete the electronic work to get the turn signals to work, any ideas on that? They stay on and do not blink and there doesn't appear to be any wiring for the rear ones.

Have pictures can post.

Mods include:
XJ rear master cylinder,
XJ front master cylinder,
XJ sport suspension rear,
XJ front fork with sport suspension
Slotted rotors from XJ?

(I bought an XJ on a whim for 150$ and the trans is trashed, i know i did a bad but i made a unique XS for sure.)

Anybody have any thought on how i can improve it with more Parts from the poor old XJ? Carbs are shot too unfortunately.

Turn signals will NOT work unless both front and rear are working. Rears should not be hard, one power wire for each side, and a GOOD GROUND.
If you let me know what you started with, year and model, I can get the wire colors for you if needed. You can trace the front signal wire back, and it should show the connection around the Right side cover, the location of the flasher. From there, if there is no wire, you should be able to run one back for each side. 16 Gauge wire is all you need for one bulb, plus a short bit for the ground.

The reason you aren't blinking IS because you aren't wired out back. I would warrant to say that you do in fact have the wiring, just not the signals themselves. I can't speak to all years but I'm pretty sure every model as a group of female bullet connections in the vicinity of the TCI under the seat. In that group you'll find a common ground and a left/right signal wire. Before worrying about any other wires, get some signals into that cluster of connections to increase the load in the circuit. Once you have everything plumbed you should be able to verify the operation of the circuit.

turns
 
There are many reasons but first find the empty plugs in the back and get those turn signals into the system. There is a certain amount of electrical draw that activates the flasher. There is an auto flasher that makes them flash no matter what you use. Bulbs were from Yamaha and 23v if I member right, have to have all four for flasher. Bad or weak connections can be trouble too.

It is a 78 i am fairly certain now. The rear brake lights work, in relation to that wiring cluster where should i look for the rear turns? I have had no luck looking for unused connections near the back.

rear signals
 
the wires were there from Yamaha, still should be unless someone did something real creative ? ? ?

T/Sig
 
Original tail light/t sig wiring is behind the license tag. Wiring up top under seat is for tail lights/t sig too, but is redundant (duplicated).

The wires at the license tag run through the underside of the rear fender.

Here is the link for the VIN : http://www.xs11.com/forum/showthread.php?t=396
If you have a 2H7 00XXXX it's a '78, 2H7 02XXXX is a '79.
Left turn is Chocolate, Right turn is Dark Green. Black is ground. Blue is brake, and Yellow is tail light. This is on the '78 E model.
On the E&F models, look at the front of the chrome rear fender for a metal tab. There should be connectors tucked under it, and they will have the turn connections. If not, as Marty said, they do have a second set running through to the tail light, so you can put them in back for hard bags. Colors should be the same, but check with a VOM to be sure!

It is a 78. I found the wires they were snipped and taped with resistors to the ground, someone must've tried to delete the rears but if it did work it doesnt now. Gotta buy some bulbs and see what i can do.

I converted to an electronic flasher years ago.. I still kept my stock flasher/cancel unit in my parts box.. Just in case.

Show it off!
 
LambdaMatters,

XS Southeast is in your back yard and coming up in a few weeks. Get on board and bring that thing to the rally! No excuses!

Would not having my license yet be an acceptable excuse? Would love to come but, yeah.

That particular plug-in under seat and top-side of rear fender IS specificly for a trailer pug-in on the Venturer 1100;). Mine is still there and original, as is all the rest of bikes wiring:).

Reviving this old thread.
 
Firstly an apology i could not attend the meet, i am currently in full time tech school so time isn't something i have alot of. I have steadily been working on my xs, its all been good but now i am back on turn signals, i bought new lights and a new electronic flasher. Thus begins the issue, the lights work normally with the engine off, but they are dimly lit and do not flash with the engine running. I am thinking that there is a voltage on the ground somewhere but i have gone over the wiring diagrams and really dont know where to start.

I'll accept any ideas you guys may have!

donebysunday 11-04-2016 06:57 PM

Check what the voltage is with it running.
It sounds like the alternator is drawing power from the system but the rotor or stater would have to be very badly shorted to draw as much as it sounds like it is from your description.
