Oops sorry. Glad you asked the question about the igniter pulsing.
When you disconnect the electrode wire from the igniter and hear the clicking it would mean that the electrode wire has a short.
I will correct my post...
You can tell if the electrode wire is open (no connection) or has connection to the electrode with your DVM.
There should be a near "0" resistance reading measuring from the igniter connector wire to the electrode. Set your dvm on 200 ohms scale... Touch the DVM leads together, you should read almost 0 ohms. Then do the connector on the wire to the electrode tip. Should read near 0 ohms.
If the electrode wire was open, no connection then you should hear the igniter clicking/snapping.
If you have 0 ohms on the igniter wire to the electrode and the screw that retains the cerramic tip is tight, and do not hear the snapping then the wire has a short somewhere there at the screw.
Jim.
