1 | Check the firm fastening of the lead connections on starter, alternator and batteries, as well as the ground connections to engine and body, retighten them | On engines 457.9, 612.9, 904.9, 906.9, 924.9, 926.9, depending on the electronic management system, the battery ground line attached to the longitudinal member is isolated through the mass point; this system avoids electromagnetic interference that would damage the ADM/PLD system. Thus, a waiting connector for bodybuilding was introduced to the electrical system at the bottom of the instrument cluster. All negative points must start from this connector, thus avoiding possible grounding on the longitudinal members. Failure to use the connector, removing the ground point or other grounding points will damage the ADM/PLD module. | |
Important: In 958 model vehicles, the auxiliary equipment is to be connected to the ground point (battery ground line) attached to the coupling housing. The ground point inside the cab is in the electric distribution center under the dashboard. | |||
2 | Check the wiring and the electric cables for attachment and mainly to make sure there are no friction points |
