How would you repair the cable of a multimeter which is broken at the inner part of the grip? Well, a Friend of myself is doing it this way: Take the bigges rubber mallet you can find, smash the grip of the cable to get out the pin and dismantle the the calbe. Then take a soldering iron and tin-solder and try to fix the cable on the pin. After a couple of attempts you made it, then put back the pin into the grip and see, that the grip doesn’t hold anymore. So what you do to finish the repair? You take the soldering iron and move it around the pin on the plastic and – surprise – it’s repaired. And the worst case repair, if you wouldn’t get the cable onto the pin: You put as many tin-solder on it as possible and cut of the rest to get the pin back to the grip.
Well, it isn’t the smartest solution, BUT it works!😀
