Solved...i just have a please delete
I see you got a Texaco Star..... nice, Imma gonna try to get a few more to join up too. Thanks for that.You're a gentleman and a scholar. Check out the sweet new badge I got!
I could also pick your brain forever on all things Trailblazer, as I am recently converted.
I do have a question for you about changing the battery. I've noticed in a lot of your replies on this forum you tell others not to remove the battery. I assume this has to do with the auto calibration of the HVAC system afterwards and the likelihood of old gears and teeth being stripped and broken. Do you have a recommendation for changing the battery without this issue?
If it helps, I have a Roco GB40 (NOCO - 1000A Lithium Jump Starter - GB40) jump box and was thinking I could attach the positive to the AUX battery post near the fuse box and the negative to a ground, turn on the boost setting and let it maintain the power while I do the swap. What do you think?
Excellent. That was what I was hoping to hear. I've noticed there are a few ground points on the chassis close to the battery. I also noticed the compressor line that snakes up and around near the engine lift spot over the alternator. If those short cables can reach, I'll definitely use that spot. Otherwise, chassis ground it is.I see you got a Texaco Star..... nice, Imma gonna try to get a few more to join up too. Thanks for that.
And ...... that's a very good way to change the battery.
I use my emergency jump box that way by pulling the fuse cover off and putting the positive on the power input to the IN positive (+) stud.
Although I take some heat for it, I just ground the negative to an AC line ... because we're not jump starting the engine ... the current pull should be a lot less than 1/100th of an Amp. I just don't open the doors (interior lights) and certainly won't try to start the engine from that ground position either.
It's just a very convenient place to get a ground ... that's all. It
mightwill create a problem IF we ask aluminum compressor lines to carry starting current.
Then remove the battery. The computers never know the battery's missing!
You'll do fine.
