Is this why my alternator not charging?

My 2004 honda crv's alternator stopped charging the battery. I tested
the 100A battery fuse and it seems fine. I tried a new battery with the
same result. I took the alternator out and was ready to replace it but
decided to check the connections to the alternator first. The b-terminal
wire read fine. I then proceeded to test the 4pin connector to the ecu.
With the battery still attached, I tested the dc current on each pin and
they all gave the reading close to that of the battery. I then tested for
resistance:

I used the voltmeter set to 200 ohms and connected the black lead to
the ground wire of the car (now unplugged from the battery terminal)
and tested the four pins with the red lead. 3 of the pins did not show any
reading but the Ignition pin showed 16 ohms. Over the next two hours of
checking around for any visible wire damage and retesting the
resistance on the ignition pin, it continued to increase and settled at 20
ohms.

My question is what can be causing such high reading and is this why
my alternator not working? Is it not getting the initial charge it needs
from the battery upon the ignition?

If all else fails, can I splice the wire from the Ignition pin wire straight to
the battery to charge the alternator (and from which battery post)? Will
this drain the battery when the car is not running?
