Testing a D38999 connector (big metal, mil-spec connector), I do a continuity check between a power pin and the backshell of the connector. There should be no conductivity (as the backshell is tied to EMI braid and grounded). When I check the resistance, there is about 300k ohms that goes up higher about a second later. If I recheck immediately, it's still high. If I wait about a minute, I get the 300k and the it goes up again. Clearly whatever it is, it builds up over time and then dissipates through the multimeter when connected. Static? Capacitance? Something wrong with the cable? The power is off. Anyone seen something like this?
