Our electrical systems and PCM'* (aka computers) don't take kindly to removing cables while running.
And then there'* the possibility of shorting the system or himself.
I am going to say this again... I seem to repeat myself a lot on this one... Do Not... Disconnect the battery cables on a Modern Computer controled car while its running.. Doing this is much the same as unplugging the internals of you home PC while it still up and running.. And in some cases a GM vehicle will stall if the battery is disconnected as the PCM supplies the power field to the alternator...
So Again... DO NOT disconnect the battery while the car is running...
If you want to do this to an Old School Chevy 350 V8 that has 0 electronics then be my guest...
Brian, please do not reccomend this unless you want to pay to repair a members car
