Screwed Threads On Remote Negative Battery Terminal Bolt

I got my traditional BlackBear tune this past summer and have loved it ever since. I did keep my stock computers so that I could swap them out when I make dealer trips to preserve the 1.5 years left on the Powertrain Waranty.

 

Anyhow, I've probably swapped computers 3, maybe 4 times so far. This past time I did it, the remote negative battery terminal bolt was so difficult to loosen that I was almost worried that it would break. I did manage to get it out and back in later but the bolt did have a messed up, "smooth" section around just one thread piece about 1/4 of the way up from the bottom. This is obviously what is causing the difficulty in moving the bolt. I don't know if it was dirt or I cross threaded or what.

 

I'm not sure what to do now. Should I just leave the bolt alone so I don't risk snapping it and forget about swapping computers anymore? Attempt to replace the bolt with a new one (assuming that the threads in the engine block aren't screwed up as well)? Or just go on like I have been but expect the bolt to be tough to move?

 

Is it really necessary to remove the remote negative bolt before removing the computers (possible electrocution, damage, etc.)?

The reason you remove the negative cable is there is no risk in arc'ing on anything but the positive cable while removing..

 

If you remove the positive cable,, while removing, you could arc on anything that is grounded..

 

Be more careful, but just remove the positive cable..

 

Other than that, might need to consider a new battery..

Something tells me he is removing the negative cable at the engine not the battery.

 

@OP: Can't you just remove the neg. cable at the battery? Why does it need disconnecting at the engine end?

Replace the bolt. But first run a "bottom" tap to clean up any damage to the threads.

Then STOP DISCONNECTING THE BATTERY CABLE FROM THE ENGINE!!! Disconnect it from the battery

A question for the the OP. It says in the thread title that you are removing the cable on the remote battery? If so you will still have power to everything. You could try filing the lower part of the bolt smooth with a small taper till you get to good threads. Don't force it to hard when you put it back on. When I bought my truck the aux batteries post was ripped right out of the battery. I didn't notice it till after I had got it home. They had just stuck it back in place and it looked normal.

Sorry I'm so late guys and thanks for the replies.

 

I was removing the actual bolt that connects to the engine body called the "remote negative" in the manual. I don't have them in front of me but I was under the impression that the BlackBear instruction called for removing it. Obviously not though.

 

So from now on, if I just unhook the negative terminal from the actual battery post I will be safe? Do you think I damged anything in swapping computers and having only removed the bolt from the engine body?

      OCI, not when but why?

      It really doesn’t matter to me. Making a blanket statement that can be refuted will be. As I pointed out the information is out there. Hey google.

      My area is one of the most affluent areas in Texas. And yet affordable housing is close by. My family business pays top wages and turnover is very low. You can’t but people in a box if you want to succeed the opportunity is there.

      AC diagnostic on a neo-classic Camaro

      By Atlas · Posted

      It was previously working, but the continually running compressor threw me for a loop. It wouldn't be out of the realm of possibility that a 26 year old AC system had lost some of its charge and could be exhibiting low charge indicators, so I thought I had it licked. Add some refrigerant to get the low and high pressures in range like on the old 134 systems.   I learned the continuously running compressor is normal, and that I need to know how much is in the system, as well as needing to meter what goes in. I'm only used to working on older R134a and R12 systems that aren't variable displacement. This is how we learn...LOL.   Long story short, I had a 20% off coupon for a new Jiffy Lube that opened nearby. I took it up there yesterday and they did an evac/recharge using their brand new machine from Mahle. Had a good conversation with the guy, they loved the car and I was out of there for $159 plus tax. Digitally measured charge, exactly 1.5lb of refrigerant went in.

      In most areas of the country, wages have trailed CPI increases over time (let's say, since the 70's) and things like housing, energy, and food have vastly outpaced wages on the whole. Can't ignore that, it's very real.   That isn't to say there aren't ways to live in ways that mitigate some of that, including moving to cheaper areas of the country. In KNut's neck of the world, median housing prices in "nearby" Dallas are more like $500k. If you're raising a family and young in a successful career, your economic opportunities are probably going to be better living closer to Dallas than Cornhole. A 3 hour (6+ round trip) daily commute probably isn't tolerable for most folks. Grumpy mentioned economic migration; but we've seen what happens when people populate and grow an area. It becomes more expensive when economic opportunities come to roost.   One thing different now from back in the 70's is our quality and standard of living has changed. Healthcare is light years better, for example. But it's also much more expensive. And we have communication and information/tech tools that folks in the 70's could never imagine, and they're accessible to people of just about all incomes. Cars are light years safer, faster, and filled with tech advances. Homes are larger, more energy-efficient, and more luxurious on the whole, from starter homes to luxury homes.   Seattle was once affordable. My folks came here in the 70's with a lot of other people from California looking to escape uncontrolled sprawl, smog, and rising prices in the Bay Area. Seattle and the surrounding area has grown considerably; The home they bought for, I think it was $70k or $80k in the late 70's is now worth $1.2M today. The same house.   So while there have been obvious boosts in some areas of quality and standard of living, regarding opportunity, that's a bit more nuanced. It's really not possible for young people to get started in similar situations in areas of the country that have become "HCOL" (high cost of living). There are many more areas than before, which is to say they exclude younger workers or make their lives significantly harder. They have to commute farther and longer to afford to live in the area. They have to take outsized risk, take on more debt, significantly delay family planning. Or, they could move somewhere cheaper, but there's usually a loss of economic opportunity that comes with that. Even for the same job, it may pay a lot less in a LCOL.   What I don't like are Boomers with phones thinking they have all the answers and outright saying that if people stopped paying for their cell phone that they'd be rich. It's as stupid and misguided as people who think they'd only be rich if taxes weren't so high. Sorry guys, Elon proved you wrong on that one, I guess you're just lazy and blaming your own situation for the reason you're not wealthy. Mobile communication is basically an expectation in a modern society and workforce and it's often cheaper than having a copper landline these days, so... What's your point?

      Ac not keeping up

      By asilverblazer · Posted

      My 2008 started exhibiting similar symptoms, wasn't 'cold' enough. I went through a pretty extensive diagnostic process for a DIY'er with limited OBD access. System evacuation and recharge included.   Noticed one day the passenger side was cold (I'm never over there so took awhile to notice).   Pulled the drivers side blend door actuator out, disassembled it and cleaned it out. Put it back in and did some kind of reset and it fixed the problem.   Long story short, it wasn't the A/C system at fault, the blend door wasn't moving to full cold position.
