Everything works but the jumper cables

Most likly the battery is old and will not keep a charge. I just replaced my battery for about $50 a few weeks ago. Go to a story like Battery + for a replacement. It worked for me.

I asked this same question about my vector system 6 months ago. My solution is " do not ask fixya.com " This is just another web site trying to rip you off by making you pay after they entice you that they have a solution for your problem. File a complaint with the BBB or FTC against Vector. You went to vector to get an answer to your problem. What did you get....fixya.com.....not vector. Why should you have to pay for information that vector should do automactically in order to support thier product. Your problem is a limit switch inside your battery box, needs replacing. The only problem is you have to pay to get that part number. It's like you going to checkers and asking for a part for your car and they charge you 20 bucks to look up the part number for you.

I just read manual and it states that the Vector jump start needs to be connected to battery before it turns on.
