I have also seen odd charging behavior by the ghost in the machine. But testing today at the battery posts with engine off, engine warm and idling, and engine idling with extra elect load showed normal operating ranges for the alternator. What could cause intermittent (one time only) high voltage DTCs in the coolant temp sensor, Electric Load Detector, O2 sensor, and MAP sensor each? Could the battery mod have effected the electric load detector in a way that is creating voltage spikes?
