1. Qoyaanka dahaarka ee jawiga qoyan, dhawaaqa soo baxa marka suunka siliga la isticmaalo, dildilaacyo ayaa dhaca, unugyada biyuhu si sahal ah ayay u geli karaan, taas oo keenta qoyaanka xargaha elektaroonigga ah. Waa lagama maarmaan in la xoojiyo lakabka dahaarka si loo ilaaliyo xargaha xargaha, ama la tixgeliyo in la beddelo suunka fiilooyinka marka ay halis tahay. calaamadaha kale, kuwaas oo sababa in aan si caadi ah loo tamar. Waqtigaan, siliga elektiroonigga ah waa inuu marka hore eego xaaladda ka dibna dayactiro. Haddii aan la hagaajin karin, tixgeli inaad bedesho xargaha xargaha. Insulator-ku uu gaboobay Gabowga dahaarka ayaa sababa in xadhkaha xadhkaha ay tamar waayaan si caadi ah, waxayna sababi doontaa kulayl xumo ama culays xad dhaaf ah oo ku yimaada daaha inta lagu jiro isticmaalka muddada dheer. Sababaha nabdoonaanta awgood, suunka fiilooyinka waa in la beddelaa wakhtiga.

　　2. Was destroyed Improper operation, damage to the wiring harness, resulting in excessive bending of the wiring harness or other symptoms, which cause it to not be energized normally. At this time, the electronic wire must first check the condition and then repair it. If it cannot be repaired, consider replacing the wiring harness.

　　3. Excessive voltage Excessive voltage leads to breakdown of the electrical layer, resulting in a failure of the wiring harness that cannot be energized.

　　4. It is possible that the insulator is aging The aging of the insulator causes the wiring harness to not be energized normally, and it will cause poor heat dissipation or overload of the insulator during long-term use. For safety reasons, the wiring harness must be replaced in time.
