Car Forum / Jeep / March 20082002 Jeep Liberty Battery Cables
I tried to remove the negative battery cable so I could clean the corrosion off, but I couldn't loosen the bolt because it has a plain round head and it isn't a captive bolt. Does anybody know if there's a trick to loosening the battery cable bolts? This round headed bolt business makes me wonder if there is some reason why owners shouldn't perform such simple maintenance thermselves. Like, obviously the radio might forget what stations it has memorized and the digital clock would need to be reset. Would disconnecting the cables cause problems for the ECU? I haven't seen the exact bolt you describe, but if it has a round head then it should be a captive bolt. Perhaps it is splined or square where it goes into the battery cable clamp, and you've gouged a round hole trying to loosen it. Yeah, that's a big problem when you have to reset the radio presets or the digital clock. It would have cost them maybe $0.50 to put a permanent memory in the radio or an auxiliary battery in the clock. You won't hurt the ECU if you do get that cable off. At the worst it will lose some memory associated with cruise control or engine performance, but it will all come back as you drive the vehicle. Again, it would have killed them to put more permanent memory chip in the ECU.

Yeah, then you would have to go to the $tealer$hip and pay them money to hook up their $6000.00 drb3 scan tool to do it. Think I'm kidding about the 6 grand? http://miller.spx.com/data/DC05-157.pdf Please don't give them any ideas... :-) /herb > I haven't seen the exact bolt you describe, but if it has a round head then > it should be a captive bolt. �Perhaps it is splined or square where it goes > into the battery cable clamp, and you've gouged a round hole trying to > loosen it. � Thanks for your ideas. It seems that the previous owner cross threaded the carriage bolt that Jeep uses for a battery cable clamp bolt and kept turning it until he also stripped out the soft sheet metal clamp. I finally hack-sawed the bolt off. I hate to use crude methods if there's any possibility that the problem is just something that the manufacturers are doing differently in their never-ending quest to maximum profits by cheapening the parts.

Giving such bad advice is going to get you in trouble. >Cheers, > [quoted text clipped - 16 lines] >> Would disconnecting the cables cause problems for the ECU? >>  SignatureJust your average Joe
