I have no idea what this thing is. Does anyone? help?
 
Well, it appears to be a mystery part ON A MYSTERY BIKE.
icon_shrug.gif


Looks like it's on the lower-right side of the frame on a bike newer than '80, possibly '82 or newer.

You have a picture of the other side?

.
 
Yah, do post picture of other side of the mystery part.

And do tell what bike model (maybe put that in sig line. Goto UserCP.)

Appears to me to be aftermarket accessory that was added.
THat wiring harnes does look like it might be hand wound black tape, right? (cant really tell).

Next question we will then ask is:
What/where is each wire tied into the bikes wiring. Unwind the balck tape to find out.

I am guessing it is a brake light modulator or maybe something to also make the turnsignal do some non-standard functions.
SOme of the wires tied into fused power (maybe org/grn), and other wires tied into the brake light wiring (wht).

This is the part that i am referring to:
It has been in place since i got the bike (1982 GS750T).
The turn signals and the tail light were both stock when i got it

the other side is flat and solid so its just this weird rectangluar block with wires coming out of one side.

I wanna get rid of it but i'm not sure what its for or what will happen.
its definitely aftermarket as i havent seen it on any schematic.
 
Can you get any info from the guy you bought it from??? He may know what it was for or why it was added.

The guy i bought it from didnt do any wrenching nor did he have a lot of information about the bike.
 
Start the bike and disconnect one wire and see what STOPS working...thats one way to see what it does.

Tell us what wire in bike wiring that each wire of the mystery unit is connected to.
 
What is That?

I recently took close-ups of my "T" and see no reason for this piece. Why are there wires connected to it? (Sorry for the continual ???s)

Here's 2 different shots:

I pulled off the electrical tape and found a black wire with a loop end on it. I figured it was a ground so I touched it to the frame while running. the rear turn signals lit up and flickered. if the ground hasnt been connected this whole time (3 months or so) it must not be operational right? so I just may need to connect the wires going into and out of it and ditch the unit altogether. yes?
 
Did you undo any of the other connected wires? Do the turn signals work as it is currently wired? Will undoing a wire make them not work?
 
alright,
i traced the wires and they all were turn signal/tail light/brake light related.

i went ahead and reconnected the wires to where they ought to go and got rid of the "unit".
i tested all the affected lights and they work just fine.

i then gathered them into a conduit for neatness

For some reason it reminds me of a trailer connector thingy.
Possibly he had some hard luggage and used to wire it in?

Wow...I need to tidy up this area of my bike--I got wires going everywhere.

Your's looks similar to mine...a little preventative maintenance will ensure both our bikes stay operational.

Thanks posting the update/resolution.

My quess is that it was brake light modulator, and maybe also had turns signals both on solid all the time except then flash the one when it needs to indicate turn.
ANd earlier you said the ground was not connected so maybe it had no effect and things operated normally.

Anyway. SO you cleaned things up some. And gained some familiarity with some more of the wiring.

And, as some folks say, "It aint really yours untill you repair or modify it some."

Really appreciate this comment Redman. :clap:

Believe it or not, I actually HAD that same little black box until I finally pitched it out while I've been going through all of my "stash". It, I believe, is a turn signal control box used with an aftermarket bags/fairing set up. Like a windjammer and the bags I used to have that were on DDaniels bike, (now Robert Bars I believe?)

Anyway the thing was in one of the bags and it was connected to the turn signals and brake lights that were built into the bags. Can't remember what brand those were... I don't know if it also did modulation as well. I never hooked it up as I never put the bags on. At one time when I picked the rig up with the 1000G I bought (twice) from Brett, I had the idea to make a bagger out of it for the wife and I, but we both decided that a bagger wasn't "Us". Lol anyway I hung onto that silly little black box for a long time, moving it with me when we moved...I figured some day someone might need one. I finally chucked it out the other day after three or four years of hangin on to it..
Never seen one before, and didn't figure id probably ever see one again. Now I have :)
