You need to confirm this before doing anything else.

Anything over .05 amps is considered a draw.

Re: 88 Iroc Parasitic draw??

10mA parasitic load (0.01 amp) is not going to cause the battery to drain over a short time period. It would take months to drain the battery at that level of draw (assuming the battery is of typical capacity and not defective).

So, if your parasitic load truly is 10mA that is not the root cause of your battery going dead overnight(?) or over a week, or even over some months.
