MN.10 - I N T R O D U C T I O N O F UPRATED STARTER MOTOR
In February '97, the starter motor was uprated from 1.0 kW to 1.4 kW, with attendent benefits to hot start
performance. In order to optimise the vehicle wiring harness in respect to voltage drop characteristics, the
power supply to the engine management system was revised and the main engine management 'Maxi' fuse
relocated from the rear luggage compartment to the front services compartment.
Updating an earlier wiring harness is not practical, and starter motor replacement should be carried out
on a like for like basis. Fitting a 1.4 kW motor on an earlier car may result in sufficient voltage drop to the
engine management system to prevent starting.
Change Point
The 1.4 kW starter motor was introduced at the following change point (approx):
VIN V 685 (February'97)
