1994 Buick lesabre
What does it mean when you take off your
live cable on your battery and the car turns
off. But you do the same thing to the
ground cable and nothing happening
the electronics what control the fuel and spark have an ECU with delicate electronics in it...a circuit needs both + and - from the battery...I shouldn't be screwin' around with the battery...you are DUE for a brand new battery at this point...be sure all connections are free of corrosion~
It means that your going to screw up your main computer and fry some other electronics, don't ever remove any battery cable with engine running on anything after 1979. I had a customer that did that to his Crown Victoria and it cost him 1200 bucks to replace everything that got fried. That being said, if your wanting to check the charging system most parts stores have that capability.
How about maybe the voltage regulator?
regulator is inside the alternator...you can check the output of the voltage regulator...should be more then 12.5 volts~ bad bad bad...may have fried the computer by interrupting the signal~
