Apparatuses, systems, and methods for preserving memory settings and deriving parasitic draw

A system for preserving memory settings and deriving parasitic draw of an electrical system of a vehicle, the system comprising:

• the vehicle comprising the electrical system;
• and
• an apparatus comprising:
• a power source configured to energize the electrical system of the vehicle;
• one or more sensors electrically coupled to the power source, the one or more sensors being configured to detect current flow from the power source to the electrical system of the vehicle;
• an analyzer electrically coupled to the power source and the one or more sensors, the analyzer being configured to derive a parasitic draw of the electrical system of the vehicle based on the current flow detected by the one or more sensors;
• and
• an interface electrically coupled to the power source, the interface being configured to electrically connect to the electrical system of the vehicle;
• wherein, based on the apparatus being electrically coupled, via the interface, to the electrical system of the vehicle while one or more cables of the electrical system are disconnected from a vehicle battery of the vehicle, the apparatus is configured to perform a method that includes:
• preserving, by providing power via the power source, memory settings of the electrical system of the vehicle;
• deriving, via the analyzer, the parasitic draw of the electrical system of the vehicle.

A method for preserving memory settings and deriving parasitic draw of an electrical system of a vehicle, the method comprising:

• energizing, based on an apparatus being temporarily connected via an interface to the electrical system of the vehicle, the electrical system of the vehicle via a power source of the apparatus;
• preserving, based on the apparatus being connected and the electrical system being energized, memory settings of the electrical system of the vehicle;
• measuring, via one or more sensors of the apparatus, current flow from the power source to the electrical system of the vehicle;
• and
• deriving, via an analyzer of the apparatus, a parasitic draw from the electrical system of the vehicle, the parasitic draw being derived from the measured current flow;
• wherein the energizing and preserving occur while one or more cables of the electrical system are disconnected from a vehicle battery of the vehicle.
