How do you remove the battery cables on an AC Delco?

Answer 1

I assume you mean the side post batteries used typically by GM vehicles. There is a small bolt in the middle of the side post terminal. Remove the bolt and the cable will be disconnected. NOTE! Remove the negative tereminal first to reduce the potential for shorting out your tools and potentially burning you.

Answer 2

I am not familiar with your Cadillac, so this answer will be generic in nature and the procedure is about the same for all vehicles. First, understand that the negative cable is grounded to the metal frame and body of the vehicle. Therefore, IF you accidently touch a wrench, pliars, or any electrically conducting metal between the positive battery terminal or connector while the negative cable is attached, there will be a major electrical arc [monster spark(s)] which could injure you or cause the battery to explode, damage the wiring and/or onboard electronics, or possibly cause a fire. Therefore, DO NOT mess with or allow any contact with the positive terminal UNTIL the NEGATIVE TERMINAL CLAMP/CABLE has been disconncted first. To disconnect the negative terminal you will need a couple of wrenches, one to hold the clamp bolt while you loosen the clamp nut with the other. You do not have to remove the nut or the bolt, only loosen it well. To remove the negative cable clamp you twist and lift it. This can sometimes be done with your hands, but if it is too tight, there are battery clamp removal tools availble at almost any auto parts supply store. Sometimes they even loan tools. Once the negative cable/clamp it totally removed away from the negative terminal of the battery, you should use an old piece of string to tie it back so it cannot accidently come into contact with the negative terminal until you are ready to reconnect it. Then using the same procedure, remove the cable/clamp from the positive terminal, being careful not to allow any metal [wrenches, pliars, etc. to come into the negative and positive terminals at the same time. To reconnect the battery, just reverse these instructions.
