Wiring problems

Could someone please send me a wiring diagram for my bike? Or just tell me how to straight wire it! Thanks in advance!

It has the thunder heart EHC! Both sides of my coil are hot but I have no spark to the plugs, could the coil be bad or the complete ignition?

Not sure on a 2000 ign but you can ohm out the coil . Since you said you get power to the coil I would check to make sure my cam sensor hasn't melted. No signal to the ignition module means no drop in voltage to fire the coil.
Someone else on the site may know what ohm reading to expect off the coil.

It ohm out at 5.1 on the leads and 20k on plug wire holes, I'm thinking I'm needing a new ignition system and I'm going bare bones on wiring, only what makes it start and run, headlight, taillight with about 3 fuses! The thunder heart harness is going to be history!

I can't tell where you are in this process but regardless of how you wire your bike it still needs an ignition system with a coil and a way to signal it. Cam sensor or Crank sensor.
I don't know if you read the coil correctly but there is a primary side and a secondary side. I would remove and inspect the coil for cracks or bad connections. Maybe go to a shop near you to have it checked out.
Rewiring your bike seems over the top when maybe a little more troubleshooting will win the day.
Did you look at your Cam sensor ? Weakest link in the ignition system and loves to fail.
Check it out and if you need one https://www.bigdogpartskingpin.com/...otorcycles-cam-sensor-early-models-04-earlier

Need to test at 10,000 ohms should be closer to 11,000 but if under 10,000 the coil is bad on a 3ohm coil

Well that’s sounds like your coil isn’t the problem. You obviously have a 5 ohm coil on the bike and those #s are good
