If it is cranking the kill switch is fine. If the kill switch was off it would not crank, atleast on any maching I have evrer seen.

Since the issue is no spark, and it is turning over I would not was time on the battery or connections. Coil is not sparking, or something not telling it to. If you have not touched the cables how in the world could they gotten swapped? Even so wouldn't they still be sparking, just at the wrong time?

You have no spark, focus on ignition circuit. I've gone through a few coils, and CPKs. Not sure what exactly XLs use. You can check voltage out of CPK. AC if rememember , few volts, should be able to google a number, or better yet look in your manual.

There are kill switches wired to the negative terminal on the coil.

Never seen one on a bike/car. Non-electronic snow blowers, lawn mowers, etc yes, they use a shunt to ground style as their kill switches.

Gentlemen,

the bike cranks fine, all lights work. For starters, there is no spark or any power to the coil. New battery tests out at 12.7 volts, yet voltage at the main circuit breaker input, direct from the battery 4” away, drops almost a full volt. With positive probe of DVM on positive battery terminal and negative probe on negative battery terminal, DVMreads 12.7 volts. Moving negative probe to ground connection at rear of engine, voltage is still 12.7. Moving negative probe to engine ground near coil, I lose a full volt. So, I have acompromised grounding system.
The front brake master cylinder leaked a full reservoir of DOT 5 silicone brake fluid thru the start switch and the emergency stop switch. I think the crux of the no spark issue lies with the emergency stop switch. After I get that cleaned up, I’ll update you on my findings. Thanks for your interest and help.

If the bike is turning over, your kill switch is most likely fine. Lack of spark has nothing to do with brake fluid in the handle bars. The switch is working fine since the starter is engaging,

If you have no spark I would investaigate ignition system. Is coil good? Is CPK good? I would focus on the ignition system if you have no spark, and engine turns over. What is coming back from CPK? I am not sure what other sensor a XL has? Does it use cam posistion sensor?

Not on any Harley Davidson that came from the factory with a kill switch.

I don`t think the kill switch is the problem, because if the kill switch was bad there would also be no power to the starter relay, and the engine would not crank.

Trace the wire back from the coil, and use the voltmeter:

Read voltage at coil.

Read voltage at the connector, both sides.

Unplug the connector, inspect the pins and sockets, look for any pins or sockets that may have been pushed out.

Don`t go out and buy a kill switch.
