Only that there is a fuel economy mode, and it is tied to the current sensor.
(And that they were considering dropping that mode for dual batts.. why?)

It's just me, I find stupid things interesting..

I understand what you were trying to say now

I saw that. If I have to live with not knowing what is causing my issue when everything is plugged in as intended, I will go this route. It'd still be nice to know what is causing my issue, though.
I didn't know they had it until well after I had bought there $400 2-pin alternator :boxed:

Interesting. So you are using one of these mechman alternators. I have had 3 of the OEM Delco alternators in my truck including the factory one that had ~125k miles on it. A part of me wonders if maybe whatever talks to the RVC system isnt calibrated properly. The two new Delco alternators ive had in the truck were ordered from SummitRacing (where i also see the mechman units sold for $$$). Summit sells a Bosch reman unit thats also 160 amp just like the delco i am using. In my deep reading, Bosch is the company responsible for this delco RVC design. Almost curious to try a different alternator and see if it makes any difference.

I am also thinking that its probably time to get a tech2. Anyone have opinions of a decent model they'd recommend?

I ended up buying the mechman because I had bought a couple other higher-amperage units and they failed within a short period the mechman has held up fine.
the newer 2015+ gm ac delco alternators are the same design as the mechman with pressed diode's
this one is probably the safest bet as you are covered by ebay if it fails to arrive or is doa
