Installation of Ignition Sense Cable
An ignition sense cable is supplied with every Mobile Radio. Motorola strongly
recommends that this ignition sense cable be used with every mobile installation of the
radio. Its purpose is to avoid the possibility that the radio may reset and, therefore, turn off,
during vehicle cranking, if the vehicle battery voltage drops below a certain level.
The ignition sense cable kit contains a thin cable and a fuse holder. To install the cable,
carry out the following steps.
1. Connect the stripped lead of the fuse holder cable only to an ignition switched
terminal of the fuse block. Use the supplied terminal or any other suitable terminal.
2. Mount the fuse holder using the mounting hole, and dress wires as required.
3. Cut the thin cable to the required length, crimp the supplied red lead to the stripped
lead of the thin cable, and connect it to the blue terminal of the fuse holder cable.
4. Connect the other end of the ignition sense thin cable to pin 15 of the accessory plug.
5. Insert the provided fuse into the fuse holder and close the cover.
