More wiring woes

[fredintoon]

Found the most likely cause of no charge on my XS11SG to be the red wire Mr. Stupid had trapped under the coil clamp and it's insulation finally wore through.
(Harness left in sad shape by PO)
Tore off old harness to replace with another one but that one's plug-ins are all different so solder & shrink-sleeve & re-tape the existing harness.
But it's been a while and where do all the plug-ins go? Refer to Clymer's & to Rob Mills' CD. Oh boy, contradictions.
CD's B&W wiring diagram (the helpful one that shows actual sketches of the plug-ins) & Clymer's wiring diagram both show the red/yellow wire to the iggybox
tapped off the fat black wire between the starter solenoid & the starter.
CD's coloured wiring diagram shows that red/yellow wire tapped off the +tive battery terminal.
So which one is it?
Please?
Anybody?

Hey Fred,

I looked at both my 79SF, and my 81SH, and the red fiber coated wire is tapped directly off the large black wire from the Battery Positive to the Starter Solenoid! That's where I'd tap it!

Also, the colored wiring diagram in the LINKS section shows the tap coming off the wire to solenoid!

Yes, but - - -

Hi TC,
thanks for suggesting I look in LINKS.
Alas that only adds to my confusion.
Yes, the braid covered RED wire is tapped off the solenoid's battery-side big black wire and goes to the main fuse behind the left side cover.
However, the Clymer color diagram shows the RED/YELLOW wire to the iggy box also tapped from the battery-side big black wire while the Lamric color diagram backs up the B/W diagram from Rob Mills' CD as they both show the RED/YELLOW wire tapped off from the solenoid's starter-side big black wire.
Either way, that RED/YELLOW wire is not fused at all and in the case that it runs from the starter-side wire, it's only powered when the starter is running.
Meanwhile, my XS11SG has an authentic-looking #16 wire crimped into the solenoid terminal of the starter-side wire but that might be a PO modification because it's got green insulation.

Hey Fred,

Looks like we may have found another error in the CLYMER's manual/wiring diagram!? Looking at this
TCI Pinout Diagram that Randy provided a while back, Pin#6 is for the Red/Yellow wire, says it's for the power supply for the coils resister bypass and so is hot when you are trying to start the bike,hence tapping on the MOTOR side of the solenoid, and only energized during starting. Once the engine starts, and you release the starter button, that wire is no longer energized, and the coils then get their power thru the common red/white wire that goes first thru the ballast resistor, and then to the coils!

So..tap it to the motor side of the big black solenoid wire!

Getting clearer

Hi TC,
Thanks for the pinout drawing.
Oh! for a magneto & no more than 5 wires
in the harness.
OK then, actually the B&W wiring diagram in my Clymer's does agree with the Lamric colored one, it's this one:-
http://members.cox.net/topcatgr/files/80SG_81SHwire.jpg
that shows the R/Y wire tapped from t'other side.
If that diagram was sourced from Clymer's
I dunno but the discrepancy is right in our own LINKS file.
I'll hook it up as you advise & let you know
what happens.

Hey Fred,

That colored diagram in the links section is from the CLYMERS! And the colored ones on the RokJok CD are colored also, and also from the CLYMERS, so I'm wondering what B-W one you are talking about? I have a B-W one at the end of my owner's manual, but I can't find one on the RokJok Cd! The only B-W one I found was for the XJ!

From what I can gleen from Randy's pinout diagram is that the red/yellow one when hot sends a full 12 volts thru the TCI to the coils bypassing the ballast resistor, but once the engine starts, that line isn't sending power, and the shared 12 volt line goes to both the TCI, and to the ballast resistor, sending the 9 volts to the coils! If it was wired to the battery side, then it would be sending 12 volts to the coils ALL THE TIME, not using the ballast resistor circuit, and eventually frying the 1.5ohms coils with a constant 12 volts. It should work fine off of the motor side!

More discrepancy

Hi TC,
this gets worse as we delve into it eh?
My 20th edition Clymer has B/W wiring diagrams. The 80 & 81 diagrams show the R/Y wire tapped off the starter supply wire. The 78 & 79 diagrams also show this but they also show the solenoid (labelled "starter button") cosied up to the starter and the power apparently going to the starter all the time.
Open the Rockjok CD and you see a page of flags to click on. 17th row up from the bottom 3rd flag from right PDF file called sg wiredia. Has B/W diagram with real sketches of what the plug-ins actually look like. Shows R/Y wire tapped off the starter supply wire.
The four flags to it's left all open to the colored diagram that has the r/w wire powered all the time.
Oh yeah!
