Wired 3g gps tracker, as the name suggests, requires wiring to power up to use, generally wired 3g gps tracker will have three lines, one connected to the positive terminal of the car power supply, one connected to the negative terminal, and one belongs to the ACC line.

So, if two of the 3g gps tracker's three wires are broken, can the tracker still track the location of the vehicle?

The first thing we can confirm is that the wired 3g gps tracker will only work if the 3g gps tracker forms a closed current loop with the vehicle power supply. If two of the three wires of the locator are broken, then the locator and the car power supply must not form a closed loop. No closed loop is formed, the locator is not energized, and it is naturally impossible to continue to locate and track the position of the vehicle.

The same goes for loose locator wires. If the locator line is loose, the closed loop is not "closed", and the device is unavailable offline.

Once the line connected to the positive and negative terminals of the car power supply is broken, the locator has no power supply source, and it can not work properly for positioning.

The ACC line of the vehicle can determine whether the vehicle is in the on or off state. If this line breaks, many functions of the 3g gps tracker cannot be used.

Of course, in order to prevent the wired equipment from being damaged without cause, more and more equipment has a power failure alarm function, and some equipment is also placed in a small independent spare battery. If the locator is damaged or the line is cut, then this independent backup power can maintain the device for 2-3 hours to continue tracking and positioning.
