I've updated the schematic a bit with the addition of part of the ignition switch, more of the fuse block and additional detail around the igniter due to the pigtail on the 2000 ignitors.
The updated version is at:

Kyre, I need you to make five voltage measurements.
For the second, third and fourth measurements, you'll need to stick a couple of straight pins into the wires at the igniter. Those will be the White (ground) wire from pin 5 of the igniter and the Red (+12V) wire from pin 2 of the ignitor.
Stick the pins through the isulation into the wire itself on the igniter side of the connector. The 2K models used an ignitor with a pigtail to the connector and it's necessary to be on that side of the connector.
Be careful! You'll have voltage available at the pins so check for shorts before you turn on the ignition!
With the ignition (key and run switches) on:
The first voltage measurement will be directly across the battery terminals with the ignition turned on and the bike not running. That measurement will provide a baseline figure for the voltage available to the igniter. Write down the results.
Make the second measurement from the battery positive terminal to the red wire at the ignitor. The red (+) lead of the meter should go to the battery and the black (-) lead down to the red wire at the ignitor. This may be a very low voltage, so don't expect 12 volts. Write down the voltage.
Make the third measurement from the battery negative terminal to the White wire at the ignitor. The black (-) lead of the meter should go to the battery and the red (-) lead to the White wire at the ignitor. Again, this may be a very low voltage. Write down the voltage.
It's absolutely critical that you make these two measurements from the battery terminals. Any other location will provide incorrect information.
Make the fourth measurement between the pins stuck in the wires. The red meter lead should go to the red wire and the black lead to the White wire. You may or may not see full battery voltage here, so don't be surprised if it looks odd. Write down the voltage.
The fifth measurement is same as the first: directly across the battery terminals. Write down the voltage.
Turn the ignition off.
If the measurements are correct the sum of the voltages measured in tests 2,3 and 4 will equal the value measured in tests 1 and 5.
Post the values you measure and the analysis of those will either confirm a problem I suspect or eliminate it and focus the troubleshooting elsewhere.
