Yep, you can test that there is no continuity to ground on the kill circuit when key is on, sounds like thats whats happening.
Check your safety lanyard line switch if you have one too, they often ground out when they shouldnt.
Im not sure which connector hole is the kill circuit, you can see if yours matches with the diagram on here

Going to try to test it the kill switch is in the key switch,I like the old way ,may be needs a new switch

Had spark with new key switch ,then none only have spark when harness plug is disconnected , does the harness have to be grounded? Or may be a bad tach. . Going to take a closer look at harness . I'm at wits end and help

Check for shorts too ground on kill circuit with plug disconnected. Run a whole new kill wire back to motor if needs be

The harness may have a short to ground on the black/yellow wire in the harness.
