1. A method by a telematics device coupled to an interface port of a vehicle via an asset interface thereof, the method comprising:
a) receiving a maximum cranking voltage time stamp from the motor vehicle over the asset interface;
b) receiving a maximum device voltage time stamp from the motor vehicle over the asset interface;
c) determining a potential alternator undercharging condition when a duration between the maximum cranking voltage time stamp and the maximum device voltage time stamp is greater than an undercharging indicator duration threshold; and
d) activating an alerting device in response to determining the potential alternator undercharging condition.
