Motorcycle wire harness wholesalers suggests first remove the wire connectors on both sides of the control computer ECU and sensor, and then measure the resistance between the corresponding terminals of the connector. If the resistance value is not more than 1 ohm, the wire is normal for the next inspection. When measuring the resistance of the wire, it is best to gently rock the wire in both the vertical and horizontal directions to improve the accuracy of the measurement. Also note that for most wire connectors, the multimeter watch bar should be inserted from the rear end of the connector, but for loading A waterproof connector with a waterproof cover cannot be inserted from the rear end because the terminal is deformed with carelessness during insertion.

(2) Short circuit resistance value check

First remove the wire connectors on both sides of the control computer ECU and the sensor, and then measure the resistance between the terminals of the connectors on both sides and the body. When measuring, one end of the rod is grounded to the body, and the other end is measured on the wire connectors on both sides. If the resistance is greater than 1 ohm, the wire and the body are not short-circuited.

Connector appearance and contact pressure check

First, remove the wire connectors one by one, check the connector terminals for rust and dirt, and clean the rust and dirt. Then check if the terminal piece is loose or damaged, and if the terminal is fixed firmly, the terminal should be loose when gently pulling. Conversely, if the plug terminal in which the seat hole is pulled out is easier than the other seat hole, the seat hole may cause a malfunction of contact failure during use.

Precautions during inspection

(1) The inspection of the connector must be carried out with the ignition lock closed, otherwise the relevant parts will be burnt out due to self-inductance.

(2) When removing the wire connector, pay attention to loosen the locking spring or press the lock button. Do not pull the hard disk hard. When installing, insert the connector into the bottom and lock it. If you want to learn more about transmission wire harness made in China,you can contact us.
