'74 TX650 Build/misadventure

[5twins]

I also run those two items as well. Both are great upgrades.

Pretty happy I found the swinger. Took a lot of looking around, and begging people to dismantle their pos parts bikes largely to no avail.

Okay!
just pulled this heap lovely machine out of the shed after...two years! Shameful.
The questions are about to start coming.
Firstly: As I'm cleaning up the wiring and greasing all the connections I noticed I don't have a female connector for the following pin terminal (White/red. Green/red. Brown. Orange. Black...Ignition switch?

Also, this black/white male connector and black female connector need a home.

Hmmm...if '74 (?) Wh/Bk, Bk may be a diode that wired into brake lining switch (no really)

Orange, Brown, Black,Wh/R...........Gn/Red? Green/Red does not compute..

 

[jpdevol]

Pic from other side of 1st block connector?

 

[AndersJ]

 

[AndersJ]

I see the diode you’re talking about on the wiring diagram regarding black/white, black.

 

[Jim]

Green/Red is an odd one. First mention of it I've found is in the 75-76 diagram.... and then only in the Legend. I can't seem to find the actual wire in the diagram.

 

[jpdevol]

I'm just thinking out loud here; the other curious thing is, in that era, they used very few block connectors. None I've found with that wire combo

 

[jpdevol]

So I checked the actual monochrome diagram from the manual (in case colorized wrong), reference to Gn/R in the table, non visible on schematic. So review:

Black = ground
Brown = general 12V+ , etc.
R/W = kill sw, coil(+)
Orange = points, coil (-)
Green/Red = ??

OK I got it wrong the LAST TIME but there is an unused connector under the gas tank for a couple years, 74-75? Might have had a function in another market.
There's been a couple threads about this but they are REAL old.

Thanks gents! Maybe @650Skull will chime in here. I did get this bike off an Australian. Possible he brought it with him to the states.

 

[gggGary]

Some years of North American market bikes have the connector, it just doesn't do anything (here).

 

[jpdevol]

So lol

Yep, we'll mark that up to strange non-US circuit that may or may not involve passing lights, 4-way flashers or brake lining switches - none of which ya need

 

[650Skull]

Pretty much anything i have to say, (with pics), i posted in the link gggGary posted............

I will add. The passing switch has no bering on the loom as it is a jump wire in the bar switch. Japanese market bikes had a Speed warning light in the dash between the Flasher lights. Hole is hidden under the dash plate. How that was wired and to what is a mystery.

 

[AndersJ]

Honestly I’ll take it as a win because I was starting to feel a little unworthy of bike ownership.

 

[AndersJ]

“Made” this as penance. Front turn signals and pilots working, as well as neutral light and brake indicator light. Cleaned all the connectors and switch internals but it’s still taking some use to wake every thing up.

 

[Wingedwheel]

I also have that connector by the coils on my ‘75 and noticed it wasn’t plugged into anything. That’s another question off my list.

I take it this hub cover is pressed on. Any tips for getting it off without dinging it up too badly?

Looks to me like it's already off. What have I missed folks? No doubt the cover will be badly rusted, I just made an aluminium replacement, looks a lot better. Same year as mine, but in much better condition. If you're not a purist, there are heaps of mods you can do to make them easier to live with: Carbs, PMA, single points or electronic, cable splitter, manifolds, cooler, remote spin on filter and so,on.

The bike pictures show mud catcher ally rims, but the hub closeup shows a chrome steel rim, did you get two sets of wheels?
