    Flame rectification circuit

    On a electronic ignition intermittent pilot ignition control is there any known methods of testing the flame sensor besides measuring amperage? Was curious if any techs had different tricks or techniques.

    The only way to check the amperage on a flame sensor is to plug it into a wall socket, Don't do that.

    Some of the newer controllers will do that for you. Other than that I agree with the other posts.

    You can find manufactuers that make test devices like Honeywell made for the 890's and Fenwall made. What brand of control is it?
    Tracers work both ways.

    True. Some will give you a voltage reading that is intended to mimic the microamp reading.

    BUT, the approach being take is the same, regardless of having a circuit do the work for you.

    As mentioned above there are several types of flame simulators on the market depending on type something like this: http://cgproducts.johnsoncontrols.co...PDF/121835.PDF
    Two wire hook up, three wire f**k up.
