Hello Tony,
I think you are getting your amps and milli-amps in a twist.
If you genuinely have a ‘parasitic drain’ of 0.06mA, you don’t have a parasitic drain!
Interpreting your meter reading:- your meter is reading 0.06 of an amp, which equals 60mA.
Does a drain of 60mA point to an issue? No - there or there abouts normal in my book.
If you have say a 60Ah capacity battery, and left the car unattended, it would theoretically take around 42 days to drain the battery.
Apologies, but what I’m missing here is what are you considering is wrong, and what are the symptoms?
