Once you push the reset button, you will just have to wait for the motor to start. Give it a few seconds until it fully starts. When the motor finally starts off, then pull up on the transformer a little bit and listen carefully for the spark to jump to the electrodes. Be careful that this spark is usually very hot and will jump a gap of about a quarter inches.
