    Anyone have any knowledge of these things?
    Service manual says peak voltage "greater than 3.0" and a couple resistance values.
    I am measuring 2.86 peak voltage and the resistance values measure good.

    If you have measured these before any idea what a typical new one, or a t least a good one measures?
    Is that 2.86 voltage value within the range of acceptable variation for these things or do I need to replace it?

    I am wondering if my meters, or the peak voltage adapter, may be affecting the reading.
    Peak voltage was checked with two different meters just because I have two of them,
    but I used the same peak voltage adapter on both meters.

    Assuming that the signal you are trying to measure is a pulsed or AC signal and you are measuring with a standard volt meter:

    Most volt meters measure average voltage, not peak. Some measure RMS voltage, but that is still not peak voltage.

    To measure peak voltage, a oscilloscope or a special peak-reading meter is needed.

    If an average-reading meter is reading 2.86, the peak voltage is likely ~1.4x the reading. 2.86 x 1.414 = 4.04
