Rotating electrics remanufacturer Autoelectro say the number of starter motor and alternator failures attributed to fluid contamination is on the rise and has issued some practical advice on identifying and resolving the issue.

The supplier says many vehicle manufacturers now install rotating electric parts either under or close to a lubricant or fluid component or pipe. Fuel filters and lines, power steering pumps or pipes and coolant pipes are all examples of potential parts which can leak onto the starter motor or alternator and triggering damage and premature failure.

Autoelectro says two vehicles in particular are very prone to this type of problem. The Ford Mondeo 1.8 TD (1993-2000) suffers from a connection fault at the oil supply line and leaking oil from the filter means fluid can enter the alternator. As the component is located under the turbo, any oil leakage from the turbo will also enter the alternator, causing accelerated wear and premature failure.

The Chrysler Voyager 3.3 (1997-2007) is also prone this issue with water contamination often causing starter motor failure. The leak needs to be located quickly, and necessary steps must be taken to prevent this breakdown from reoccurring again.

Information on these issues, as well as technical bulletins and tips can be found on the Autoelectro website. The company’s team of experts are also contactable 24-hours-a-day via its online chat facility, available at www.autoelectro.co.uk.
