6.0 at the shop, but would like a second opinion

I have been running my truck (2006 F-350) with no problems. I went to pick up a 5th wheel travel trailer that I just bought on monday. When I hooked up the 7 way cable my battery light came on, I assumed it was due to the trailer sitting all winter (I am in Alaska) and not being charged. I towed it about 40-50 miles to my house, the battery voltage stayed around 11v with the light on the whole way.

The next day I went out to warm up the truck and the truck was reading 7-8v, but it still started. The radio went out, AC/Heater went out, head lights flicked on and off. I parked, removed the alternator (passed 3 tests at the local auto parts store), then called for a wrecker. That was about as far as I feel comfortable going into the truck. I was reading error code P0620.

The shop said that I needed a second alternator, although I have been running the truck since I bought it last October with one, and through an Alaskan winter on top of that. After that, they said that the PCM may need to be replaced, and I hear that those things almost never fail.

Ever hear of suddenly needing a second (lower) alternator after running one?

We just had a customer bring in a dodge that had the same issue with a dump trailer. The power and ground to the trailer were switched in the trailer plug. When the truck sits the dump battery would draw on the vehicle battery until dead. I would check to see if thats what your running into first. Should be easy to do with a multimeter.

Are they doing the pinpoint test(s) or just whacking away throwing parts at it?

At my last recollection I had a customer who had an alternator tested a couple different places on the bench, and it checked out ok. A new alternator on the truck fixed the charging circuit issue.

You don't need a second alternator, and even if you did - if an independent shop doesn't have IDS, they aren't going to be able to turn the parameter on in the PCM anyway.

The charging strategy in these trucks also doesn't ramp the alternator up until a couple minutes after the truck has been running, FWIW, so I hope they aren't just firing it up and looking at the low voltage and going "Nope, she's ****ed!"

The shop said that they did the pinpoint test. It's not the dash and the alternator was checking out okay. I ran the truck with the trailer for about an hour the day before it died. I would think that that would be enough time to charge the battery. Hillbilly, you up here in AK?
