multiple sparks

[spuzi14]

Electrodes come in pairs, just for the record.

Are you getting a spark on any of the electrodes?

BTW, to get 3 sparks you need at least 4 electrodes, and usually there would be six.

You also need to keep the wires well separated since the insulation on most wire is only rated for a few hundred volts. If the wires are too close together at any point then you'll get the spark jumping between the wires instead of across the electrode gaps.

Take the gun into a dark room and dry fire it a few times to see if there are any sparks jumping where there shouldn't be.
