As I posted recently, I had my alternator rebuilt to 120 Amps and got a new
battery (825 cca).  The alternator was shot, and the battery was fairly
tired as well.  I�m about to put a 17 amp heater in, so
I wanted the alternator to be able to deal with the extra load.  So I�m back
up and running, van starts fine, and the battery light stays on for a second
or two and then goes off.  When I have all my accessories on(radio, lights,
heater on high blower), my vdo reads 14+ when I�m driving but drops down
right around 12 when I idle.  Is this OK?  I don�t even have the heater in
yet and I feel like the system is overtaxed.  Am I missing something?
