Hoping for a quick answer here as I’m trying to help out a young intern at work. She has a 2000 Volvo S40 that is at a dealer right now quoting $415 for a possitive battery cable replacement. Has anyone worked on one of theses cars? I’d think it is a pretty straight forward repair, but a quick goog search didn’t give me much. I’d like to offer my help, but I don’t want to get in over my head with anything… Thanks, Mike ---

i would assume the job itself isnt too hard but I bet the cable is expensive/dealer only and cant be bought at pep boys because of the special connections on it ---

cable from alt to batt??? make your own from 4ga and some terminals for like 10 bucks? getting to the alt could be another story. Did the dealer give any more info on the job? ---

Probably a remote mounted battery in the trunk or something. Only reason I could think of for it being so expensive. ---

Dealer told her that the “cable had exploded”. My thoughts were to simply remove the cable, go buy what ever length to replace, new terminals, and be done. However, I’m curious to know a few things: \*exactly how much damage is done to this alleged exploded cable \*is there any other wire nearby that could have also been affected, thus shorting something out somewhere else in the system. I have no problems replacing a cable…I’m just hoping that’s all it is and is an easy fix on these cars. Car has a new battery, which is mounted under the hood. ---

So the cable is a few hundred bucks. Not that crazy considering there are plenty of crazy prices on OEM parts. Just go look at it, figure out what you need and replace. /caseclosed ---

> [@walter](#): > > Open up the hood… we can’t tell you. I’m not asking you to diagnose this problem. I’m looking to see if anyone has worked on these to tell me what the possitive battery cable replacement entails. The car is at a dealership in Amherst and would need to be towed to my house. Rather than give her the 100% go-ahead to drop this at my house, I was hoping for some feedback from someone who’s parhaps dealt with a car like this. Just found out about this a few hours ago, and I’m at work in EA so opening the hood right now is out of the question. ---

I closed it. I googled “S40 battery cable” or something like that, clicked through 2-3 pages, found a 16MB pdf titled “tp3959202\_s40\_v40\_2002\_wiring\_diagrams\_section\_3\_39.pdf” among others. ---

One thing to consider with regards to the cost of replacement is that some cars have a much more complicated “B+ cable” or “positive battery cable”. It’s not necessarily just one cable going from the battery to the starter etc. I have not replaced or dealt with the cables on S40s but I do remember replacing the B+ cables on S70s. These ran from the battery terminal through the body harness and into the engine fuse box. The routing and removal of the old wiring made this a time consuming repair. Is the car at the Volvo dealership in Williamsville? [Next page](https://forums.speedlife.net/t/2000-volvo-s40-possitive-battery-cable-replacement/68642.md?page=2)
