I am using TEST LEDs and in test mode, the test LEDs blink every few seconds, is this normal?

Yes, it is perfectly normal for the TEST LEDs to blink every few seconds while in test mode. When testing the continuity on the 18M, a small amount of current is sent into the cues, 25mA @ 18V using hardware A and 5mA @ 18V using hardware B. This level of current will be noticed on sensitive LED bulbs but is not enough to fire any igniter.

Please see Hardware Hammered Out for more information on hardware A and B.
