Well i just had my truck in for service. They checked the battery and charging system and all checked ok. I did have the truck in stock mode and left my Gryphon at home. $80 later.... truck is fine.
They didnt find any draw on the battery. Charged the battery, changed the oil and sent me home. I dont drive the truck all that often (Ive got a company vehicle) so it pretty much sits most of the week. I really dont want to have to unplug or connect a battery tender everytime i come home. Is there a way to 'turn off' the memory function. I dont think i need the data stored in the unit. I mainly use it for monitoring temps and such while i tow and fuel mileage.
