Hey all I'm in need of some assistance. My dad has been in and out of ICU with heart problems so I'm blaming anxiety for my brain not getting this figured.
Here's the deal:
My charge light was on earlier this morning. So figuring a bad alt. I put a charge on it for 15 mins with charger and drove to my shop. Sure enough via multimeter, I got battery voltage at alt output, ~12.3 v. Easy enough as I have a parts truck with low miles and a known working alt. as of a few months ago. So I swap it out and I'll be damned it's the same issue.
Here's what I'm working with:
Truck is baselines to the max
New agm battery
I had rebuilt the first alt. 3 months ago and is oem
Swapped alt. Is also oem
Charge fuse good
New fusible links last week
All connections tight and clean
Now in looking at the FSM diagram it's telling me I should have 0-4 volts at the black wire with ignition on. I have 12v at all terminals with ignition on and that has my head aching. Any help here would be great.
I work on cars everyday so coming in for a question like this really tells me my head is in a bad place.
