Battery saver active warning after big 3

[Lsufan51]

I just did the big 3 in my 08 impala and ever since I'll get a battery saver active warning on the dash and the a/c will cut off. Has anyone else had this problem and how do I fix it?

[SPL.Pantie.Soak]

Did you remove the factory wiring when doing the big three or did you keep them both?

[Lsufan51]

I kept the stock wiring. Just add 0 gauge to it.

Check for bad connections, if you are just adding wiring it should hurt anything.

Try removing those added grounds. At least the alt to battery one.

[Lsufan51]

There is a battery current sensor on the stock power wire. I'm gonna move it to the new power and see if that helps.

Try and put both power wires through the current sensor if you can

[Lsufan51]

It's too small. I can't get them all through it.

If you have the one from front to back batteries in there, replace it with the alt to batt wire. If not, then I have nothing further.

[Lsufan51]

I don't have any batteries in the back. Just a yellow top up front. I'm going to replace the sensor and cut off the connection on the 0 gauge and see if I can put it in like that.
