Suzuki 2006 C50T Electrical

I'm looking for a wiring diagram so I can install an alarm system. I
need to know how the ignition switch is wired. If it cuts power or
grounds the ignition like a magneto would be grounded to shut off the
engine. And finally is the ignition system a single fire or dual fire
ignition?
Can anyone help out please?

 

Look in the back of your owners manual. The red wire goes from the
battery to the main fuse to the ignition switch, the orange wire comes
back to the fuse box to power everything that is supposed to be powered
when the key is on.

So you need to power your alarm from the red wire or run a wire with an
inline fuse directly off the battery positive terminal and you need to
get the arming/disarming signal from the orange wire.

Don't power your alarm from a wire near the handlebars that a thief
could easily cut.

Battery and coil ignition systems on street bikes use the ignition
switch to supply power to the coils.

Very few street motorcycles have magnetos, but it's common with dirt
bikes. The only street bike I ever owned that had a magneto was using a
part from a production roadracer, it didn't come stock with a mag.

And finally is the ignition system a single fire or dual fire

I dunno. Why don't you just remove your spark plugs and reconnect the
spark plug caps and ground the plugs and turn the key on and watch to
see what happens when you thumb the starter button.

Both sparks at once = dual fire. Alternating sparks = single fire.

If your Screwzuki has carburetors, it doesn't need a single fire
system.

If it has fuel injection it will have a crank angle sensor on the side
of the engine or on the end of one camshaft that tells the ECU when to
squirt gas to which cylinder.

The reason Harley went from dual fire to single fire was they put fuel
injection on the Road King model. The older dual fire system triggered
two sparks at once, using a single sensor to send a signal to the
ignitor unit and it didn't matter that one spark fired while the
exhaust valve was still open.

But, with fuel injection, they needed a different, single fire system
to keep the fuel injector from squirting a shot of gas to the cylinder
that was on the exhaust stroke.

An advantage to using a single fire system is that it eliminates the
V-twin rumble in the exhaust. That comes from burning excess fuel in
the exhaust pipe when the
waste spark fires.
