Are you telling me that this procedure will track down a voltage leak when the car is parked/stowed?
If your steps are true, you need to apply for a patent on the procedure my friend!
I'm going to try your steps on my bird (which has a slow leak that kills the battery in 2-3 weeks when sitting). If this works, the Pope will be calling you shortly. I'm not kidding, this is comparable to the cure for common colds. I want this to work!!!
