No need to marry them for this reason, only if a new one was added. Is it really a 2002 as the category says as sometimes the category model year is not the correct year for the bike in question.
Test the primary coil resistance on your coil. Disconnect all the wires going to the small terminals (primary) on your coil. Using a good ohmmeter on Rx1 setting, test the resistance between the two small terminals. You should read somewhere between 2 and 3 ohms. If you read more, the coil is bad. Before you do this test short out both leads of the ohmmeter and if the reading is not zero you will need to write down or otherwise remember the number and subtract it from the reading you get from the primary circuit test or you will have an incorrect resistance reading for the primary wires because you will also be reading the ohmmeter internal resistance and/or the wire and lead resistance added to the primary wiring resistance.
You can also test the coil by leaving the "hot" wire on the coil and replacing the other side (ground side) with a short piece of wire. Turn the ignition on and temporarily ground the short piece of wire you put on the "out" (ground) side. When you take the wire away from the ground, (which will collapse the primary current into the secondary) you should see a spark at the plugs if it is a wasted spark system or at one of the plugs if it is not a wasted spark system. If you have current to both sides of the primary of a two part coil both plugs should get a spark whether wasted spark system or not as you are energizing both sides of the primary and collapsing both into both secondaries at the same time when you remove the ground wire from the cylinder head ground.
Take the plugs out of the cylinder heads and lay them back on it so that they have a good ground. Then watch the spark plugs closely when you turn the ignition switch off. You should see a single spark on each plug. This tell you that the coil is getting fire and that it is good and your problem lies elsewhere. You get a spark on both plugs because it is a wasted spark system that fires both plugs simultaneously, one on power stroke and the other on exhaust stroke.
This will not work on 2006 etc EFI as there will be no spark with both plugs removed.

chk backwards to your turn signal control unit. The brake lights and rurn signals are routed in a way that would affect each other.Is this a four wire or?Chk fuses 1st. Good Luck- -Ned- A good grd is important.

The original wires, one blue and one white, were with the points ignition. The white wire should be the "Hot" wire. Now, look at your wiring diagram. The two white wires should go together to one side of the coil and the blue to the other. There is no positive or negative side of the coil, just two small primary winding terminals. Make sure the white wire from the ignition system is the "hot" or power wire for 12 volts. If you connect the ignition unit up backwards, it will damage it. To make sure the white wire on the bike is the hot wire, simply turn the ignition switch on and check this wire with a test light or volt meter. It should show battery voltage on it. That should be your setup, two white wires on one end of the coil and a blue wire on the other.
Good Luck

Look for both CKP (Crank sensor) which you have tried, as well as CMP(Cam postion sensor) Those go out too often.

itss your ignition module ..its toast the black box it cheaper to get the wwhole ignition kit on ebay about 160
