Abstract
A system and method for monitoring the state of health of the connection between a generator and a battery includes detecting an interruption in power between the generator and the battery, incrementing a counter each time an interruption is detected, generating a trend of a number of interruptions over time based on a number of increments in the counter, monitoring a rate of increase in the number of interruptions over time and determining if the rate of increase in the number of interruptions over time is greater than a predetermined threshold.
