Inside Line: Autoelectro

Our Technical team have advised me that a stretched or worn alternator belt can cause premature failure of the alternator pulley, and that it is important to check the OE numbers for the alternator as there are quite a few outputs and stop start options on both starter motor and alternators fitted to later vehicles.

The starter motor can fail prematurely due to excessive cranking caused by a worn ignition switch that keeps the starter motor engaged when started.
