2019 Honda CR-V LX 2.4 ALTERNATOR NOT CHARGING BATTERY WITH NO CODES

Checked voltage on the following 2 wires:

yellow wire (single wire alternator)= 10.8v plug and unplug

Black = wire going to the fuse block inside engine compartment.

The alternator is grounded to the chassis. Externally grounded.

My problem is that I can't find a way to give power to the brown wire that powers up the charging circuit indicator lamp.
I checked all the fuses under the dash on the driver side, inside of the vehicle.

This circuit is power side switched. I'm going to include a picture of the circuit.
What's the easiest way to find that brown wire that goes to the lamp on the dash. I don't have any codes to guide me.

I wanted to do the test that Paul showed me where he would give power to the bulb circuit and the alternator would begin charging the battery again.
Right now, I need help in finding that wire in this vehicle because from the inside, I would have to take out seats to work comfortable. Thanks.

What is the alternator charging at? On Hondas it’s normal to charge at 12.6 at idle.

The alternator wasn't charging. From 12v, it kept declining.

yes, I checked all the 10A fuses. They were both off on both sides of the fuse. I pulled them out and checked them physically. There's 3 rows of fuses. I didn't have a guide like the one under the hood that tells you the fuse and what it controls. So I checked all 10a fuses.

Forgot to mention, I hear a slight whistle coming from the tensioner.

Do you have a scanner that can do a self test on the cluster? Might just be a bad cluster

I have an autel. I scanned all modules and it showed no problems. nothing, nada. I was hoping that that would guide me. But zero.

that's why I want to put my test light to B+ and do a bypass test on that brown wire but I can't find it.

thank you

THIS IS A FIX. I was able to fix it. don't know how. Charging voltage returned.
I put a load on the alternator by turning on lights, accessories etc, voltage jumped up to 14v plus. It's a fix. If anything comes up, I'll post it again. thanks again.

That’s what I said. It’s normal on the Hondas to charge low at idle no loads.

with the vantage pro, what does a good waveform look like, hooking up to the batt terminal of the alternator? Do you have access to those waveforms?

You get all the credit Cheryl thank you.
