DIY'er here: I am trying to determine the amp draw during a parasitic drain test on my 2005 GMC Envoy. Other vehicles I've tested the draw is generally pretty stable....not so much here. Starts out at about 3.8 amps and then ends up dropping down to about 0.30. As it's all over the place, what's the real draw....the beginning or the end? The battery goes dead if it sits more than 48 hours. Here's a 50 second You Tube video of the meter:
Any help would be appreciated.
