Thanks. These docs seem to imply that the jumper terminal under the hood is always connected to the main battery, so if I use that I'll have to remotely put the ranging circuit in sleep mode to avoid draining the battery when it's not in use. I'm thinking a simple keychain style pushbutton remote inside the cabin to turn it on for say 3 minutes before automatically shutting off again. So many ways to skin this cat...
