Was thinking about running 93 octane… is this really necessary? And than add some chevron with techron? Heard good things. Someone said IAC so maybe it is idle related. Idk

It's all I run! Of course she'll run better on 93!

As part of RVC, when the truck first starts, for the first minute or two or however long the computers decide, the alternator runs at full output before switching to another charging schedule. That's what that tester was seeing. Now, if she's always running at full output, the alternator is trying to keep alive a bad battery.

On my scanner my truck was already warmed up when I did the load test at 2k rpm on the alternator. I did it twice and it said bad and than said warning on the second go.

You think mine could be running at full output all the time? That would explain the over charging guess I don’t know. At the same time even though my truck was warm. I did have to restart it to do the test so I’m not sure if it has to go through deciding how much power it gets each time you start it or what

Make sure the RVC is plugged into the current sensor on the negative cable right off the battery. If unplugged, the alternator will run at maximum output all the time.
