testing for parasitic draw

A continuous load of 50 mA totals 8.4 Ampere-hours in a week, which seems like a reasonable goal, although we can only guess about the spec for the Maverick. The main problem after this quick inspection is how to isolate the parasitic load to a specific circuit (module). There is often more than one such culprit. A normal process might involve monitoring at the fuse block either by direct measurement or indirectly, from the voltage drop across each fuse (calculate amperage using fuse resistance). For some unfathomable reason, Ford made this incredibly difficult by mounting the under-hood fuse block upside down so you have to unplug it to access a fuse.

Posted because I thought it was interesting - the value ?. I do have deep sleep issues, fortunately it continues to start. I am hesitant to replace the battery with an AGM due to having a 5 year vehicle ext warranty. I am concerned that every electronic issue will be met with "non OEM battery, no warranty repair". when it doesn't start roadside assistance will be called

I've had my hybrid 13 months and have had only 1 deep sleep issue after (I think) 6 days of sitting. After that, I've started putting a charger on it around day 4. Normal flooded batteries are designed for "SLI" service (Starter / Lights / Ignition) which implies they do not do well in a deep-cycle environment. IMHO, these should never be allowed to get as low as the Mav seems to do, since the battery takes some damage each time.

You can use one of theses.
The wonvon unit will log volts and amps.

Can you share some info about your fuse box connector?

You like that,
The current unit I purchased does not have the adapter for micro 3 pin.
That one was made from flatten copper wire until the correct width and thickness.
It’s incased in plastic JB weld.
I imagine you can purchase something like that online.

Why yes, you can buy something similar: Micro2 Extension holder:

...but I'm a sucker for a good home made solution.

Instead of the copper, I think you may be able to use the little spade connector/disconnects: Male Spade Connectors:
