Starter zero current test apparatus and method
First Claim
Patent Images
1. An alternator and starter tester for testing a starter motor, comprising:
- a software that controls a starter zero test;
a first switch, when closed, allows power to a transformer;
a second switch, when closed, allows power to a solenoid of the starter motor;
a current meter that measures current flowing on a power line; and
a processor that communicates with the software, the first switch, the second switch, the transformer, the solenoid and the current meter, wherein the starter motor fails the starter zero test when the first switch is activated to allow power to the transformer and current is detected as flowing.

Abstract
An alternator and starter tester system having a starter current zero test. The current is measured before and after a solenoid of a starter motor is energized and deenergized to determine if the starter motor should be failed. This allows the operator to quickly determine if the starter motor is stuck on during normal starter motor testing.
