Starter motor testing device
First Claim
1. A control test device for testing a dual starter system having a first and a second starter, each starter having a starter electrical interface including a starter crank signal interface and a starter status signal interface, the control test device comprising:
- a first communication interface for communicating an electrical test signal to the first starter, wherein the first communication interface includes a first electrical interface for interfacing with the first starter electrical interface;
a second communication interface for communicating the electrical test signal to the second starter, wherein the second communication interface includes a second electrical interface for interfacing with the second starter electrical interface;
a switch mechanism operable to direct the electrical test signal to the first starter or the second starter, each of the first and second starters electrically interlocked from starting unless the corresponding starter receives a neighbor-status signal indicating that the other starter is operational; and
an electric circuit for generating the electrical test signal directed to the first starter to test whether the first starter is inoperable when the switch mechanism is operable in the first position, the electrical test signal including;
an electric crank signal communicated to the crank signal interface of the first starter to start the first starter; and
an electric status signal communicated to the starter status signal interface of the first starter, the electric status signal simulating the neighbor-status signal indicating that the second starter is operational.

Abstract
A control test device for testing a dual starter system has a first and a second starter. Each starter has a starter electrical interface including a starter start signal interface and a starter status signal interface. The control test device includes a first and a second communication interface for communicating a test signal to the first and second starter respectively. Each communication interface includes an electrical interface for interfacing with the first and second starter electrical interface. The test signal includes a start signal and a status signal. The start signal interfaces with one of the first and second starters start signal interface. The status signal sends a simulated status of the other one of the first and second starters to the one of the first and second starters start interface. A switch mechanism commands the start signal to one of the first and second starters.
