The collectives pool of electrical knowledge is deep. (sounds dangerous) The
Professor is a welcome recent veteran addition and Jazz is an emerging
rookie sensation. Then there's me and I don't even have the excuse of youth.
After twice falling off, shattering and leaving me stranded my stock kill me
switch is long circumvented and gone. However, I occasionally miss this
resource. The kid at the counter said a Yamaha OEM, button, spring type was
the way to go. Some kind of serious dirt thing? Looking at the diagram (14-8
supplement manual) seems clear that the engine is shut off by connecting
BK/W, hot with BK/Y, ground. Can't figure how connecting not breaking shuts
something off...oh well. Put the Yamaha switch to the multimeter, sure nuff,
when the button is pressed it opens not closes the circuit. Guess I'm not
the brightest light in the LED display. So....I need to break BK/W & BK/Y
and connect one switch wire to each, right? Besides not really understanding
how this works, am I missing something? Also this type of switch only shuts
the engine off for a second as it instantly springs closed. Guess this means
if the bike is in motion the engine will kick over and restart? I have
tubing but it doesn't work optimally when you break into a wire with only
one wire. Never saw any T-type shrink tubing. Any ideas? All input will be
appreciated. Bogdan

Bogdan,
Your observations are right on the money. You clearly know
your (electrical) limitations & that's good! At the risk of
boring you & others, I'll cover a few basics. Switches come
in many configurations:
momentary - push to complete or break a connection
normally closed (NC) - switch completes a circuit until
pressed
normally open (NO) - switch breaks a connection until
pressed
single pole, single throw (SPST) - switch handles 1 wire
connection: on or off
single pole, double throw (SPDT) - switch handles 1 wire
connection: controls power to 2 possible circuits
double pole, double throw (DPDT) - switch handles 2
separate circuits. This setup is like 2 SPDT
switches that are tied together.
In the "old" days of magneto ignitions (without CDI), a switch
was used to "short" the low voltage side of the ignition system
to "ground" to prevent ignition spark. The KLR kill switch
is a modified DPDT (with center run position). In the OFF
position, the BK/Y (ground wire) is connected to the BK/W
wire, as you stated. Without knowing the CDI unit s internals,
it appears that grounding the BK/W going to the CDI unit is
what SAFELY stops ignition spark. This OFF position
simultaneously disconnects 12 volt power (from the BROWN
wire) going to the STARTER button. I m assuming that the
highly esteemed Kawi engineers did this to protect us from
ourselves (duh, why is my engine cranking over, but it won t
start?).
I would NOT use a momentary type switch to kill the engine.
Just be sure to buy a good quality switch that will stand up to
the KLR s good vibrations. Don t try to 2nd guess the
engineers, if you decide to break the ignition circuit
somewhere else to kill the ignition, you may fry the
(expensive) CDI unit when 12 volt power is left on. This
shouldn t be a problem if you use the BK/Y & BK/W wires at
the handlebar (& i'm will to bet YOUR CDI unit that i'm
right).
See the enclosed attachment for using heat shrink tubing with
multiple wires.
Additional notes on heat-shrink tubing:
Tubing comes in many sizes (diameter) & colors. I use tubing
sized no more than 50% larger than the wires.
Tubing is meant to shrink UP TO 50%. Don t try to shrink the
tubing more than this.
Don t use excessive heat to shrink the tubing super tight, this
will cause the tubing to split.
Always solder electrical connections to ensure a secure
electrical connection & prevent future corrosion. Soldering a
connection is never done ONLY to ensure a positive physical
connection. I solder all connections, even wires with crimp
connections.
WalMart sells a digital multi-meter that includes a 0-10 amp
d.c. scale for $18 (USD).

Far from boring, Professor. Printed it out for my actual file. Thanks a lot. Why wouldn't you use a momentary switch to kill the engine? Why did Yamaha make and sell this thing? BTW You coming to Moab? Bogdan> At the risk of boring you & others, I'll cover a few basics. Switches > come in many configurations: >
