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
