Parasitic draw with ANY regulator
 

Good Evening,

I have an interesting problem here that is not easy to pin point.

When metering the negative post on the battery to its respective, unconnected terminal (leakage test), there is a constant 12+v parasitic drain on my battery as long as there is a regulator rectifier plugged in.

It does not matter which regulator, I have tried 2 healthy ones that have the same connectors, and have tested one different but healthy rr using alligator clamps. All are giving me the same reading.

if I unplug the rr from the harness, the voltage reading drops down to about .20~ volts.

The amperage reading remains at zero, although it does read 12+ Volts.

One thing to note is that if the voltage is 12V and current 0A then the power consumtion is also zero (power = volts x amps) so there will be no discernable impact on the battery. So long as you have 0V when the ignition switch is in the Off position then this is pretty much as I would expect to see.
