Nope, just recheck your connections and make sure they are actually connected (they work when tested with a multimeter).

Well, here are some universal instructions…

Find a selection on the multimeter that is for ohms (Omega symbol) and touch the two probes together. If it reads zero, when you touch them, you're in good shape. Look for some sort of setting that seems to make sound. If you find one that you touch the leads together and it beeps, that's what you want. If you can't find a way, you'll have to look at the multimeter for every connection, a disadvantage, but not a huge problem nonetheless. Then test your connections, one probe to the actual pin in the cartridge connector and the other to the place you soldered the other end of the wire. If it reads 0/beeps, you're in good shape, move on. Make sure they all work, then test the ones adjacent to eachother and make sure it DOESN'T beep. This ensures you didn't solder 2 pins together or something.
