SG Starts in gear - Clutch Safety Switch?

[kboehringer]

XS Folks,
My SG will start in gear without the clutch engaged and there does not appear to be any sort of safety device to prevent this.

My '81 Maxim has both a side-stand & a clutch safety switch. I assumed something was screwy with the SG but I would figure it out later.

Yesterday, I purchased another SG for parts/spares and found that the clutch perch contains a switch which my SG does not have. I followed the wire to the headlamp area where it connects to a green connection from the main harness. I checked my SG and there is no such connector. A quick trace of the new bike reveals an extra OMRON relay under the seat area my bike does not have.

The switch on the perch has a B/Y and B wire to the green male. The female green connector in the headlamp has a BW & B wire. These appear to flow all the way to the "EXTRA" Omron under the seat area.



What gives? I can find NO reference to the clutch safety switch on ANY wiring diagram for ANY XS model.

Anyone got any ideas? I sure would like to have a clutch safety switch so I can't accidently launch this beast through the kitchen an into the living room.

Sincerely,
KURT

There is no clutch safety switch on an XS, only XJ's. The XS counts on personal intelligence.

The green female within the main harness (that this switch attaches to) is too stock looking for this to have been added by a PO? Although hacked up a bit here & there, the main harness does not look like it's been screwed with?

Still confused about the green connector........

I've seen that green connector on an 81 harness and could never figure out what it's for. What is it plugged to there?

[kboehringer]

YES. I suppose there is a chance this is an 81 harness.... There are a number of post '80 parts on this bike..... Maybe the bike is actually an '81?

4R0 is a serial number for an SH. Sounds like you've got an '81 frame with a '79 motor.

Guess so.... The motor does have a kicker and I knew it was earlier. That explains the green connector and several post '80 parts..... Shouldn't matter too much on any of the spares I've already grabbed. The ignition module worked fine on my SG and that was a primary reason for purchase.

Thanks for the helps guys - Feel like a real dumb butt again now...:mad:

Hi Kurt,
You have a Frankenbike
My 81H has the clutch switch.

Did you check the model number on the TCI? If it's a 4R0 type then chances are you've got the '81 advance parts under the timing cover. Something to keep in mind if you ever swap motors. And those 4R0 TCI's are pretty hard to find, so if you've got one you could probably get rid of it pretty easy. Catatonicbug might be interested as his doesn't test properly.

Yup. That's an 81 frame with a 79F engine. You have to check out a LOT of stuff in the ignition and controls to see what's been intercourse up by the PO.

dbeardslee,

Yes! The TCI is labeled: TYPE TID14-04 & 4RO-10 / 005. When I got this bike home I quickly snatched the TCI out, plugged it into my DUCK SG and the bike started right up. I was too stupid and in too much of a hurry to check the #'s on it as I assumed it was for an SG. But, it seemed to work fine. I gave the SG a couple good snaps of the wrist and it sounded fine. However, I did not actually drive the bike with this TCI.

This was probably the single most important reason I grabbed this POS bike at the elevated price of $300. I've seen XS11 TCIs sell on evil bay for anything from $50 to well over $200 so I figured if it was good that was a good piece of the purchase price very well justified. The peace-of-mind that I had a spare in my saddle bags is PRICELESS!

You can probably still use the 4R0 but you'll have to transplant the advance stuff. The earlier models had a mechanical advance while the 81's are all electronic. Or just find a 2H7-10 TCI.

I had a platoon sergeant that taught me how to spell "assume" many years ago.

[dbeardslee]

Another thing you'll probably find on the dead duck is different coils. The 81's used 3 ohm coils while the '79's had 1.5 ohm with a ballast resistor. So if you transplant the coils you'll probably have to bypass the ballast resistor.

You can tell the difference between the '81's and the earlier models by looking at where the high tension wires go into the coils. On the earlier models the "wire tunnels" are both the same length. On the 81's one tunnel is shorter than the other.

You still have a working emergency TCI even with the Advance messed up. It will get you to safety.

Long as you've got enough gas in the tank 'cause fuel economy is going to take a hit without the advance working properly. If you're carrying a spare, it's better to carry the correct spare.

KB - I'll bet you could talk Catatonicbug into picking up a 2H7-10 to swap with you. They're a lot easier to find than the 4R0's, and his 4R0 is producing a flakey reading on his black/white wire.
