Finally, the hissing you are hearing is a clue telling you that your coil is putting out really fucking high voltage. The hissing is the air being ionized because it is in proximity to metal at a very high voltage potential. You sometimes hear the same hissing coming out of the back of old TVs.
The reason it is so dangerous is that you are completing the circuit if you touch the battery positive or negative. When you touch the plate without touching the battery with the other hand, you don't complete the circuit and you feel a high voltage tingle. I would still consider that to be dangerous.
Your multimeter is reading about 97 VRMS. However, the multimeter was designed to measure 60 Hz AC, not 3 KHz AC, so the reading is much lower than it actually is. It could really be 300 VRMS.
Everything connected or indirectly connected to the high voltage output of the ignition coil is fluctuating up an down in voltage, ant the positive and negative peaks could be very high, 400+ volts. The insulation on the plate and the wire is along for the ride and will give you a shock when you touch them.
This could be very dangerous. If you touch the positive or negative of the battery anywhere in the circuit with one hand and touch the plate with the other hand it could kill you.
Hey there Nat, this posting is a serious public service announcement for you, Bodkins, and others experimenting with earth ground, and especially for those like yourself that are using a virtual earth ground in the form of an insulated plate.
There are many ways of describing what is happening with your experiment. Here is a basic one: You are connecting the HV output from an ignition coil to a metal plate and wire. You are electrifying the plate at high voltage AC.
