Great response. That is exactly the information I was looking for. Now, is
there a place that I can monitor the voltages at refs #3 and #10 to know
for sure? It looks like I can probe at the fusebox for ref #3 but probably
can't find where to probe #10. If I could find a place to probe #1 I could
monitor it with a scope and see what is happening.
On my old Dodge Caravan I could hook my OBDII reader to laptop and read
program memory and find the stored values when someone published the
locations online. With the more modern cars I can't find any such info
(and my old spec 9141 interface won't read cars after 2007 anyway).
Since the circuit consists of only alternator, battery, TIPM, and PCM
and all was good until alternator failed, it seems to me the new alternator
is the problem. According to Advance Auto Parts it is the correct one and
the specs published online indicate that.
Most valuable to me would be would be a wiring diagram showing the wires
and connector pin numbers were I could probe.
