<< REPAIR OF IIE/IIC MOUSES ======================== Help! I have 5-6 IIe/IIc mouses, all with the same fault! They scroll vertically, but not horizontally. Someone told me that its indicates a broken wire. But which wire?? Is the break likely to be at the DB-9 plug, or at the entry point into the mouse's housing? I do most of my typing on the IIC+ (I have five of the IIC+!), so fixing these IIe/IIc mouses is very important to me .... Thanks, Steve >> Man, I've fixed a few hundred Apple and Mac mice. What I do in your case is this: Take apart the mouse, and remove the cable assembly. Take the strain relief (the one that was attached to the mouse)and slowing break it loose from the cable itself. Slide it up the cable about 4-6 inches or so. Strip away the sheath so you have all the wires exposed a good 4 to 6 inches or so. Tug real good on each wire and you'll find the broken one real quick as it starts to stretch. If you have the patience you can just cut all the wires and resplice them into the wires coming out of the connector, replace the connector with new pins, or just solder the wires directly to the pins on the mouse circuit board. I usually cut and reconnect personally. But once you do the trick above, you will have all the strained wires inside the mouse, and you can start fresh with all new wires at the point of strain relief. I have also used the same technique when you have a bad wire at the strain relief on monitors. Raymond
