If I leave my car off for a few days, the battery dies. I have a lot of aftermarket equipment in my car and I guess I could just unplug each one and see if it stops the power drain, but I'd like to do it a better way. Is there a way I can measure a drain like with a multimeter or something? I wonder if I used a MM to test for amperage, with the power unpluged on the device, it would give me a negative value, thus telling me how much amperage the device is draining. Any other thoughts? I'm sure someone has done this before for standby battery drain. BTW, I use hibernation on my computer, so it's completely off.
No announcement yet.
