A kill switch should interrupt the power to the distributor not ground it. You have a major short if wires are getting hot. I think you are sending power straight to ground. Wire the switch inline with the power wire to the distributor.

Take some pictures of your wiring and post/link them. Along with the all the ignition and charging system. If you draw up a sketch of what your wired that would be helpful. a + and - on a box for the battery. Keep disconnecting stuff you wired. a test light in line with the wiring at the battery can help diagnose. The brighter the test light the worse your short. Do you have fuses on components? Hate to see your ride turn into a ball of fire. Don't hook up the battery until you can't light a test light inline with one disconnected cable and the battery.

To install the kill switch, you splice the two wires coming from the switch between the wire on the distributor. The switch will act as a breaker. By you grounding the wire, you created a major short. You may want to install a fuse in the line as well so it doesn't fry wiring and will just blow the fuse.

I bet you popped a fuse, (why the Alt. light is on). The alternator exciter wire is generally on the INST fuse. Could be why the buzzer is buzzing too. Check them all with a test light, any fuse that's hot on one side but not the other is blown. There will be one or two that have no juice unless the H/L switch is on, and probably one that has no juice unless it's in the crank position, the one you're looking for will be hot with just the switch on.

Mods- the OP seems to have posted the same basic question here in Electrical as well as on the Hotrodding Basics forum, HERE.

Suppose you could do a merge?

To CTK- you need to only post your question once in the proper (Electrical, in this case) forum...
