I have noticed that functionally similar SBEC and SBEC2 will draw different currents.
I have tested approx on dozen SBEC and SBEC2, their standby current is approx, 1mA this is with pin#3 (battery) ON.
The next test is to place IGN power to pin9 (IGN) this varies from 0.1A to 0.5A. I was not expecting this large of a range so I thought to change the electrolytic caps just for fun as my LCR determine the existing caps are in good shape.

Has anyone noticed this before and ,if so, were you able to repair/fix
