stock battery charging configuration
I've been looking around the web for an answer to this, and my search techniques are failing. I can't seem to get a straight answer:
In a 7.3L PSD van (1997), are the two stock batteries always connected, or is there a solenoid/ isolator in there somewhere? If there is a separator, on what parameters does it operate?
My house battery is going in, and I planned to connect it to the system via the second (framerail mounted) battery... Any reason why I shouldn't?
Thanks in advance for the help. Some of this electrical stuff confuses me deeply.
