Glo igniter circuit indicator

  1. Aug 15, 2012 #1
    For starting glo ignition model aircraft engines, I use an igniter that attaches to the glo plug via wires and a connector. The igniter contains (1) AA NiMH rechargeable battery, 1.2v, 2200 mAh.

    I would like to insert an LED or other device in series in the positive lead which would light when either the battery is dead or the coil in the glo plug has failed. It should use an absolute minimum of current so as not to hinder the operation of the glo plug.

    If anyone has a suggestion, I would love to hear it. I'm not an engineer, so keep it as simple as possible, thank you.
