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.

Electrical testing system and method

Electrical tester

Display screen or portion thereof with graphical user interface

A battery clamp for use with (a) top post terminal connections and (b) batteries with side post terminal connections includes a first and a second jaw handle. The first and second jaw handles each have a handle portion and a clamping portion. The first and second jaw handles are pivotally coupled to each other and are biased with the clamping portions in a closed position. The battery clamp further includes a side post adapter. The side post adapter is coupled to the handle portion of one of the jaw handles. The side post adapter includes a load pad and a volt rod. The load pad has an aperture, through which a portion of the volt rod protrudes.

Battery clamp for use with top post and side post batteries and methods for using the same

A battery clamp for use with (a) batteries with top post terminal connections and (b) batteries with side post terminal connections includes a first jaw handle and a second jaw handle. The jaw handles each have a handle portion and a clamping portion. The jaw handles are pivotally coupled to each other and are biased with the clamping portions in a closed position. The battery clamp further includes a first jaw member and a second jaw member. The jaw members have a jaw clamp portion, a jaw pivot portion, and a jaw wire portion. The jaw pivot portion of the first jaw member and the jaw pivot portion of the second jaw member are both pivotally coupled to the jaw handles. The battery clamp further includes a load pad and a volt rod. The load pad has an aperture and is coupled to the first jaw member. The volt rod is coupled to the second jaw member and protrudes through the aperture of the load pad.
