A method for predicting immanent damage to a connecting point between two electrical conductors in a motor vehicle electrical system is disclosed, wherein a value of an electrical variable is ascertained that is at least related to an electrical resistance of the connecting point, and wherein the prediction of the immanent damage is made depending on the value of the electric variable. The value of the electrical variable is repeatedly determined while the motor vehicle electrical system is in operation while an operating current of specified operating current strength flows through the connection point.

The invention proposes a method for cohesive joining to a cable end (), in which method a welding tool element () is fitted on an open bundle end of individual cores () of the cable end (), welding energy is fed into the individual cores (), and the welding tool element () is removed from the bundle end. In the process, an engagement recess () can be formed in the open bundle end, an engagement pin () of the welding tool element () can engage into the engagement recess (), and at least a portion of the welding energy can be fed via the engagement recess (). A configured cable comprising individual cores () with a receiving sleeve () is also presented, wherein the receiving sleeve () has an inlet opening () for a bundle () of the individual cores (), the receiving sleeve () has an end piece () which is widened in relation to the inlet opening (), and there is, at least also in the widened end piece (), a cohesive connection between at least one subset of the individual cores () with respect to one another and/or between at least a subset of the individual cores () and the receiving sleeve ().
