newby needs some help

Can anybody post a link of a wiring diagram for a 84 suzuki 1200

Mine is not firing, no spark at the plug

You don't really need a wiring diagram in order to figure out the
ignition circuit.

Oh, and it might be a really really good idea to let the world of
supposedly generous people who you're asking to do your work for you
which model of Suzuki you're talking about.

Apart from that, good post. Well done.

It is a Madura I think built 5/84 hell it might be an 85 model
Just took it in on a trade and trying to see if its worth fixing .

You might be smart enough not to need a wiring diagram, but you haven't
seen this wasp nest someone has left out of the wiring system.

Oh, God, one of them? The v4 thing. OK, you've got your work cut out :-)

Ah. Fair comment.

Look, buy a manual, even a factory manual at Eeek price. It's worth it
in the long run.

Just a word of advice.
Post in the subject what you need advice on.

I don't happen to have a wiring diagram or a link to a wiring diagram,
but the transistorized ignition system Suzuki uses is just not all
that complicated,
there are two power transistors inside the ignition module and they
receive a low voltage signal from the two signal generators which
sense the motion of the alternator flywheel.

If the engine cranks rapidly when you push the starter button, the
flywheel is passing the signal generator coils and inducing the
necessary voltage to tell the transistors to switch off, collapsing
the electromagnetic field in the associated ignition coil and causing
a high voltage spark.

A quick check to see if the ignition coils and ignition module are
getting power is to remove the spark plugs and reconnect them to the
high voltage leads and turn the ignition switch on and off rapidly.

Everytime you turn the key on and off, you should see a spark at one
of the plugs.

Take off the side cover, exposing the black plastic transistor
ignition module. It's about as big as the palm of your hand. Carefully
unplug the larger plug that has about four wires.

Turn on the ignition switch, and make sure the kill switch is in the
RUN position.

Using a voltmeter set on the 15 volt scale, check for 12 volts on all
the pins in the wire harness connector.

If you have 12 volts on three pins, you're getting power to the coils
and the ignition module. If you don't have 12 volts on three pins,
start checking back to the ignition coils, the fuse panel, the kill
switch and the ignition switch.

The 3rd wire in the connector will be the ground wire. You can use
your ohmmeter to check continuity to ground.

The smaller connector comes from the signal generator. Set your analog
voltmeter on about 3 volts DC and spin the engine with the starter.
You should see the voltmeter needle jump up to about 1.5 to 2 volts.
Also, try the test on the AC scale if your needle doesn't jump.

Most electrical problems are caused by bad connections, and I would
hope this is the case, because the ignition model for one of those
bikes costs about $500 and is discontinued.

If you have an electronic tach, watch the tach needle as you
crank. If the trigger circuit is working, an electronic tach will
show RPMs while the starter is cranking the engine. An
engine analyzer should show the same thing connected
to the -12 volt lead from the coils.

Check for +12 going into the coils.

Using an ohm meter, check continuity through
your plug wires and through your coil.

Check your kill switch.

You need a wiring diagram.

Good luck.
