Normal. The 14v start up voltage applies to a cold engine.

Ok, after the clip on multimeter gets here it's game on. I'm a tool freak so more is better. Ordered a spin on oil filter adapter and Mann 103 Filter.

No no. You should be able to use a flat head screwdriver to engage the locks on the door and frunk when they are open. When you're done with all the testing, just hit your remote to unlock the door and unlock the frunk to reset the locks.

Aha....so push them in with screwdriver and latch them shut. Thus, they will stay closed, until unlocked.

Exactly! This way the computer will think all the doors and frunk are locked like normal so it will arm the car like normal and start to power down all the electronics such as interior lights, DME, etc.

You've got a problem. 335mA is a sizable drain. Btw, if you leave the meter clamped onto the cable for a long time, say a few hrs, you want to remove the meter and zero it again before taking any reading.
