    had a totally dead battery so I dismantled it. The only problem I saw was the red wire wasn't connected to anything.

    was really easy to take apart with hemostats to hold the male screw end, while using a small swiss army knife blade to pop the brass ring and gently pull the insert out.

    what now? have plenty of USB cables around here. I know we need a switch of some sort. My husband will be making it, so I need some instructs for him.

    Appreciate any help!

    On the battery connector the center post is your positive, and the outer ring (thread) is your negative. Strip or unsolder the positive and negative leads from your usb cable. Wire in a tactile momentary switch, and if you want an led w/ resistor, and then connect the leads from the switch to the battery connector.

    thx ruuku! he'll know what that means ;) I'm packing up all my carts, charged batteries and will clean the attys. I wanted to see if it works better (or at all) on a PT before stashing it away.

    appreciate it
