Battery clamp connection detection method and apparatus - Patent 6667624 (Site not responding. Last check: 2007-10-11) |
 | | A method for testing a connection includes sensing a first voltage in a cable carrying current to at least one of two and from a connection, sensing a second voltage associated with the connection, comparing the first and second voltages, determining whether the connection is acceptable or not acceptable based on the compared voltages. |
 | | A connection test may be performed at either the positive 240 or the negative clamp 238 connection by applying the connection test to the positive components 230, 240 or negative components 232, 238 of the battery tester charger 200. |
 | | The connection test may be performed by comparing the voltage in the battery cables 230, 232 upstream from the connection of the clamps 238, 240, and the voltage at the connection of the clamps 238, 240. |
