Abstract
Abstract An automatic, portable solid state voltage regulator tester, specifically made for testing Ford and General Motors regulators. The face of the tester has contacts arranged for the manual application of either of the regulators and the regulator under test is held against these contacts with the thumb. A merit switch is pressed and if the meter rises to a marked area, pauses for a moment, and then drops to zero, the regulator is satisfactory. If the meter does not rise, or if it rises but does not drop back to zero, then the regulator is defective.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
A battery powered voltage regulator tester wherein the batteries provide a source of potential, including a plurality of contacts spaced to fit the particular regulator under test, a switch to apply the potential to the regulator comprising a pressure operated blade and a plurality of normally open contacts, and a capacitance and a bulb connected across a pair of said switch contacts wherein the capacitance developed in testing is discharged through the bulb to flash said bulb when said switch is deactivated, and a meter which indicates the amount of potential used by the regulator.
Claim 2
Dependent Claim
95 words
A battery powered voltage regulator tester wherein the batteries provide a source of potential, including a plurality of contacts spaced to fit the particular regulator under test, a switch to apply the potential to the regulator comprising a pressure operated blade and a plurality of normally open contacts, and a capacitance and a bulb connected across a pair of said switch contacts wherein the capacitance developed in testing is discharged through the bulb to flash said bulb when said switch is deactivated, and a meter which indicates the amount of potential used by the regulator.
Claim 3
Dependent Claim
25 words
The device of claim 1 further including a second switch to connect the batteries to the meter to thereby indicate the charge on the batteries.
Claim 4
Dependent Claim
14 words
The device of claim 2 wherein said first and second switches are pressure activated.
Claim 5
Dependent Claim
24 words
The device of claim 1 in which said meter is color coded to provide areas of demarkation which denote functional and faulty voltage regulators.
