Detecting Leakage Current in a Vehicle
Let''s put it straight: there is no leakage current in the starter. We have a slightly different concept here - an increasing value of the starter crank current, and consequently not enough battery current to start the car engine. This may be also caused by the wrong battery capacity (the battery was incorrectly selected).
