+ | - the alternator is running at its most efficient RPM((~6, | ||
+ | - airflow from the forward motion of the vehicle helps remove heat from underhood | ||

+ | Assuming people are going to do it anyhow, here are some steps to reduce changes of a Bad Outcome: | ||

+ | * hot smells | ||
+ | * belt squealing | ||
+ | * engine RPM dropping significantly | ||
+ | * chassis voltage falling from normal levels (14.1v, or whatever you observe without charging) | ||
+ | * charger reporting less current than usual, if applicable | ||
