2002 Explorer 4.6 FWD 4G alternator Built 7/01
No voltage at alternator plug for I circuit with key in RUN.
I have spent some time online looking for a wiring diagram for the charging system, I have seen some labeled 2002 Explorer, but I have my doubts. CJB, AKA fuse block under dash, fuses 15, 16, 21 have been removed, inspected, and replaced. No effect. Seems like there should be a fuse for I circuit, but I have not found it.
My alternator plug has two wires, lg/rd and or/lb.
Turn key to run, red battery light comes on, turn key to start, battery light goes off a few seconds after engine starts.
Battery voltage at rest, 12.5, voltage running, 12.8, voltage with headlights on, 12.3.
Alternator seems to be doing something, but precious little. But without voltage to turn it on, amazing that it does anything at all. Residual magnetism?
What do I need to do to get voltage to the I circuit?
FWIW, alternator tests fine at local parts store. These folks are my friends.
Thanks,
