Re-solder the new system connector by using a hot air blower, and a soldering iron if necessary. Check that the system connector is straight and exactly in right place.

4.2.1.3 Test

Charging problems can be discovered by measuring the voltage between pins 1 (Power) and 2 (GND). Voltage should be between 5V and 9,5V if system connector is working.

In order to detect an accessory when plugged into the system connector, the following pins on the connector are used in the detection scenario: POWER, TX/D+, RX/D-, DATA/CTS, CLK/DCD and RTS. Table 1 shows the pins and their possible use in a detection scenario.
