I was just basically after a simple (if possible) continuity tester that only requires a small current and voltage to flow through the object in question (in this case, Estes model rocketry ignitors). All that it needs to do is light up a LED when the circuit is complete. Power supply will be from the main circuit, which uses 4xAA 2000mAH NiMH batteries.
I would rather stay clear of using an LED with a resistor to limit the current through the test circuit.
Thanks in advance.
Edit: I should have said that by "simple" I mean a circuit that is the bare minimum to suit the use. I don't really need all of the bells-and-whistles that a few of the circuits I have found have. As long as its relatively small, and is able to indicate continuity using a low current.
Edit 2: Now with crappy sketch goodness:

This is just a rough sketch, as I do not have the design software on this computer at the moment.
