Is your EverStart battery charger a smart charger ? mean does it protect against reverse charging ?! It is easy to get things crossed up with normal positive ground , this could have damaged the alternator

By disassembling and examining/testing all the components the failure can be isolated and then repaired and/or part(s) replaced. But, what caused it is another story, possibly a poor quality part, possibly an external cause.
As other's have said there may be a problem w/the car's wiring.

According to the Everstart web site, I caused the problem when I miss-connected the charger.
TKS for everyone's input, going back to my spare Generator

My alternator began giving me issues with the original size belt. I couldn't get it tight enough so it would only charge under light load (i.e., the belt would start slipping under higher resistance). I ordered a smaller belt and will see if that fixes it.

Actually it's a new belt when it 'failed'. Anyway It waited until I send a spare off for rebuilding before it began to charge again. I'll keep checking.
Thanks

Sounds like it may be an intermittent connection somewhere.

Well, your not going to believe me, so here goes: When I stand Passengers door, alternator shows a charge. Drivers door, no charging. I checked this 6 times.
I have a 2024 PaceMaker if that's a clue.
I've a video to prove my post, just don't have the skill needed

You think your pacemaker is interrupting the charge? Or interrupting the ammeter? That is a scary thought!
When I got my pacemaker/defibrillator years ago, they told me refrain from getting too close to magnetic fields or running engines. At first I was afraid to start my Model A! Seriously!! But all was good when I got brave. I did stop electric welding tho on the advice of my electrician (Electrophysiologist) and plumber (Cardiologist).

I added the info about the pacemaker, just in case. And I'm keeping my video as proof when our club meets. Alls I know is that the Ammeter shows either a charge or neither, depending on the doorway I'm at. I'm along so I don't know where I'm at when it does it's thing. I can/t very well removed my PM

I'm not supposed to weld with my pacemaker and don't, but the manufacturer's rep that downloads data from it twice a year says that she has welder patients who have continued their livelihood with no apparent bad effects. She didn't advocate it by any means.

Since I'm not touching my truck to view the ammeter, I don't know what to think -- right now, it's my presents in the door way -- but I enter it to video (for my proof).
Now I do have 4 stents, and two new hips, just last year.
What I need is a close club member to drop by, but that's not going to happen.
I really need someone else to see this

It's clear when I'm passengers door and when I blow the horn, the ammeter moves smartly to charge(15), when drivers door it moves to discharge(15)

Does this phenomenon occur when someone else stands in the passenger door? Or just you?

I have no one to assist me, so until I do -- I don't have an answer.
I'm hoping a club member will help, we meet tomorrow, but that's 50 miles
North. There's not a whole lot of Model A interests right near
