Why is my 97 yamaha banshee not fireing or getting any spark??

SOURCE: 1987 Honda shadow vt1100c no spark at any plug

The voltage on the coils is present except at the instant of firing. The interruption of the voltage is what causes the coil to fire. The cdi box is what causes the voltage interruption.
The interruption is very hard to detect. You are not the first to be stymied by that box. If you have access to an oscilloscope, I think you can see the pulse if it occurs.

follow the plug wire back to the coil and see if there are any breaks, if not might switch coil with the other one and see if the other plug now misfires, if so replace the coil, most cdi problems are not intermittent, typically they either work, or they dont.

Hi and welcome to FixYa,

The voltage on the green wire must be pulsating when cranking/starting the bike, not steady. Confirm by similarly testing the voltage on the black wire on the left ignition coil. If the green still reads a constant voltage, then the CDI is faulty; to be more specific, most likely that the switching tansistor inside the CDI that drives the right ignition coil has shorted.

Good luck and thank you for asking FixYa.

YES IF YOUR KEY SWITCH IS NOT HOOKED UP CORRECTLY THE BIKE WILL NOT FIRE.....

• Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
• Is the handlebar kill switch on? Is it shorted out?
• Are you getting power to the coils?
• Check the fuses. How good is the battery? Try a jump start from your car battery.
• Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing. If still no spark, get CDI system and coils checked at the dealers shop.
