With the prodding of Rick G, I've been able to locate the current drain in my car (Don't worry, I'm still going to install the battery isolator). It turns out to be Lockzilla pulling about 30Ma with the "remote" unit plugged in, and 20ma without. The total current draw from the battery when the car is off was 30Ma until I totally disconnected Lockzilla - then I get a zero Ma reading on my meter. Apparently, this drains the battery down about one volt per week - enough to cause the auto-shut off to kick in, which was my original problem. Has anyone else noticed a slight current drain with Lockzilla (with or without Remote), or could I have a defective unit? -Hank Eskin #1619
