Abstract
A method and system for measuring, determining and/or analyzing the cranking RPM of a vehicle is provided. The system measures the voltage of at least a portion of a vehicle's electrical system to determine high and/or low voltage time periods during at least a portion of a starting or cranking cycle. The time between high and/or low voltage points can then be used, along with the number of cylinders in the vehicle, to determine the cranking RPM of the vehicle. The system may include a load module and a control module that are removably coupled to one another in first and second configurations.
