Abstract

A vehicle ignition system detection device is cooperated with a diagnostic unit and includes a detection unit. The detection unit includes multiple ignition system output holes and multiple detection cables. Each of the detection cables has a plug end and a patch end. Each of the plug ends is inserted in the ignition system output hole corresponding thereto, and each of the patch ends is connected to the coil corresponding thereto. The electro-magnetic detection signals between the patch ends and the coils are sent to the display screen of the diagnostic unit so that the maintainers are acknowledged the conditions of the ignition system.

Claims

1. A vehicle ignition system detection device installed between the coils, comprising:

a diagnostic unit having a first IC circuit board located therein, at least one switch, a display screen and a first I/O connection port installed on an outside of the diagnostic unit;

a detection unit having a room defined therein in which at least one second IC circuit board is received, the detection unit having a power input hole, a detection device output hole and multiple ignition system output holes defined in an outside thereof, the power input hole, the detection device output hole and the ignition system output holes electrically connected with the at least one second IC circuit board;

a power connection cable unit having a first end and a second end, the first end of the power connection cable unit inserted in the power input hole, the second end of the power connection cable unit connected to a battery;

a connection cable unit having a first end and a second end, the first end of the connection cable unit inserted in the detection device output hole, the second end of the connection cable unit 80 having a plug which is inserted in the first I/O connection port, and

multiple detection cables each having a plug end and a patch end, a number of the detection cables being the same as that of the ignition system output holes, each of the plug ends inserted in the ignition system output hole corresponding thereto, each of the patch ends connected to the coil corresponding thereto, electro-magnetic detection signals between the patch ends and the coils being sent to the display screen of the diagnostic unit.

2. The vehicle ignition system detection device as claimed in claim 1, wherein there are eight ignition system output holes and eight detection cables which are connected to the eight ignition system output holes.

3. The vehicle ignition system detection device as claimed in claim 1 further comprising a second connection cable unit, the diagnostic unit having a second I/O connection port connected to the outside thereof, the first and second I/O connection ports electrically connected to the second IC circuit board, the second I/O connection port connected to an operation device via the second connection cable unit, the operation device connected with a storage device by wire or wireless to read information in the storage device.

4. The vehicle ignition system detection device as claimed in claim 3, wherein the diagnostic unit has a positive connection port and a negative connection port defined in the outside thereof, a detection member is electrically connected to the positive and negative connection ports, the first IC circuit board has a detection unit, an A/D converter unit, a processing unit and a display unit, the detection unit is electrically connected to the connection ports and receives analog signals input the connection ports, the A/D converter unit is electrically connected to the detection unit and receives the analog signals and transfers the analog signals into digital signals, the processing unit receives the digital signals from the A/D converter unit and processes and compare the digital signals, and creates a result which is sent to the display unit which shows the result in forms of digits or patterns on the display screen of the diagnostic unit.
