What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Doubeleive]

I was trying to help my neighbor with programming some new fobs on his NBS Hummer. He programmed some new ones while the Hummer was right next to his sons NBS Silverado and they ended up programmed to the same code, so the fobs lock/ unlock both vehicles at the same time. So I mentioned he needs to program them while the trucks are a ways apart so he drove the Hummer down the street. Still does it. He also has a Compustar alarm on the Hummer ( on it when he bought it) and has also had battery draining issues. He said he wants to get rid of the alarm so he found a module under his dash and he decided to unplug it. Not sure which module it was but now the Hummer won’t start. Not sure if it’s in fail safe mode or whatever, thinking someone was trying to steal the vehicle. Wondering if anybody has any experience with either issue, maybe Wes @Doubeleive ?

Have him plug the module back in and see if it starts if it does then he probably needs to have a shop remove it, if there is a starter kill on it then that could be the problem

He plugged it back in, no el starto. He’s gonna call Compustar and see if there’s some reset procedure. I’m thinking it sensed someone tampering with the alarm and disabled the starter. It has remote start so I’m assuming it has ignition kill. The fob turns the alarm on and off but the truck won’t start.

Usually just disconnecting the battery should work

He said he was going to try that, I’ll make sure he does. Thanks.

Keep in mind that an additional, hidden battery is sometimes added when those aftermarket alarms are installed... If it doesn't reset it the first time, leave the batter unconnected for 3-5 days, and the additional battery will drain.

Ordered a Mechman 240A alternator and a 1/2" shorter serpentine belt per their instructions. Hopefully it fits correctly. Replacing the 145A original.

So before I do my 2500hd grill conversion I am looking at this chrome plastic and thinking I should take the time to paint it black first.
Any tips on how to de-chrome the plastic? I see some say use a bleach/water soaking mixture, or use oven cleaner, or just etching primer.
Anyone have really good long lasting results with a simple method?

I fixed my no crank issue, found a spot on the wiring harness under the hood that’s been rubbing on a coil. It just happened to wear through both the ground and crank voltage wires for the starter relay. It wasn’t even really noticeable, I just saw the harness laying on the coil so I lifted it up and used a mirror to look under there. Starts right up now.
