T-tap loop wire splice connectors are used to connect the Base Station to the Perimeter Wire. When there is no connection, the Base Station cannot transmit a signal to the Perimeter Wire. This signal ensures that the robotic lawnmower knows where the mowing area is.
When you store the robotic lawnmower in winter, the t-tap loop wire splice connectors often break. Sometimes the splice connectors are lost or need to be replaced. Make sure you always use properly working t-tap connectors, because the robotic lawnmower cannot mow without a signal. You can easily replace the connectors yourself. Always check the manual of the robotic lawnmower to see exactly how this works.
