who here removes the cable from the battery before working on a vehicle, like most instructions usually say to do first?

most any of the installers that i work with do this.. it is a good practice to have and helps prevent any "problems" that you could have during install. ------------- you can do it....

Any professional should do this. Not paying attention to basic safety procedures is asking for trouble. ------------- Support the12volt.com

I always get a circuit breaker instead of a fuse for my power wire - so I usually trip the circuit breaker when I work on the car. Removing my battery terminals is a *real* pain. ------------- "I'm finished!" - Daniel Plainview

On newer cars disconnecting the battery is not allways the best idea, plus depending on what your doing you need to best testing circuits.
with alot of newer cars you need to be carefull not to turn the ign key on with any oem plugs disconnected or it will send an error message to the computer, I found this out on a brand new Mercedes, thankfully a couple of trips around the block cleared it up.

Yes as USAbuilt says, some new cars disconnecting the battery causes a ton of problems that the dealer only can fix. We had some chryslers (300, magnum, etc) when they came out if you disconnected the battery when you reconnected it a ton of lights were on and the car was stuck in limp mode. Not cool. In 16 years I have hardly ever disconnected a battery before working on a vehicle. Only exceptions are when its absolutely necessary, like when pulling off a steering wheel or pulling out a seat with bags or sensors in them.

johnmax.... I like "limp mode" thats good! I agree with USA, depends on what I am doing to said car. Big toonage etc. doors open for ever, cars around in the shop for a few days.... or more. A deck and 4, or a simple 1 or 2 amp setup, an alarm/remote start, NOPE! (how do you test anything with the battery unhooked?) -------------

I agree with not having to remove the battery cable every single time your working on a car. But in newer vehicles like johnmax said, it's a good idea to disconnect the cable when having to remove a seat with sensors in them. I had a 08' silverado in my shop for a simple amp job, but had to mount the amp under the seat. Not wanting to take a chance with any error messages, i disconnected the cable and no problems. Most other times i wouldn't have done that, but newer GM vehicles are getting to be real pains in the @#4.

99 % of the time i dont disconnect the battery. just use your head, simply put that if you ground anything power you may have issues. hook up the power last if you can and if you have to disconnect the battery they make memory savers that you plug into the wall and plug into the cig lighter with a 5 amp fuse that will blow first if you screw up. If you disconnect something like a VW beetle have fun resetting the security on the radio ------------- The greatest revenge is living well and showing it

A lot of the issues with pullin seats and unhooking airbag connectors I found, come from turning on the ign. to test something then pow..... idiot light. (i'm an idiot) done it couple times. Worked in a shop that did ALOT of leather, and seat heaters. Me, the 12V guy, I get to wire the switches....they want me to test before they put the seat back in.....BS, you can take it out again so I am not the guy that triggers the SRS light! So in those cases, yes.... disconect the battery. -------------

i discconect the negative terminal off any car that will stay in the shop for more then a couple of days. there are exeptions as many have mentioned in other post but for the most part there is no need to kill a custumers battery if the car is just sitting there while you work on pods or a box or something. ------------- life is a comedy to think, a tragedy to feel
