What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[PG01]

I also put a brand new battery in yesterday. All day today the voltage gauge is under 14. While yesterday it was above 14. Does this have to do with the amp sensor not turning on the alternator?

Yes

if you want, hit tow haul button while idling and watch gauge. It creep right up to the middle and hang there.
Yesterday it was probably charging and today it doesn’t need much. It will go up when needed.

Nice bath and quick detailer job.

Thanks for the tips. I presume this all applies to the GMT800 platform as well..?

Yup. All the same.

Pretty sure you can disconnect them halfway up the middle of truck and reroute them under axle then reconnect.... they are at least 2 pieces

This. I disconnected mine to route above the sway bar (but still below the axle) when I lowered it to give some slack on the shock body. You gotta put a little ass into it to pull 'em to disconnect, but they'll unhook fairly easily if they're not corroded. You're gonna have to replace that/them cables since water has already gotten in and is rusting the cable inside.

Disconnect the RVC sensor on the negative battery cable and see if the voltage goes up and stays up.


*EDIT*

I'm slow to the party. I missed the last page.

Never knew the Tow/Haul function altered this. I can see the benefit.

117k

the 02 sensor's are rated for 100k they usually last longer but I would replace all 4 then you don't have to worry about them for another 100k
