[VHFcontesting] Alternator/VR question for rovers or auto guys

[Jarred Jackson]

Thanks All,


A search for "Ford Smart Alternator" confirmed what you suggested. There is also a temperature input to the Engine Control Module which alters charging voltage based on presumed battery temperature/condition. Apparently this is common in vehicles.


I will test again tomorrow when its supposed to be warmer and be ready to add load to see if it kicks back to higher voltage.


Feeling much better about this.


73,

My thinking, too.
