Inside the DISCO floor polisher, part 3245 is the wiring that moves power from one component to the next. SEBO draws it at position 21 on the machine's parts diagram. This is the internal harness rather than the external mains cord that plugs into the wall, so it is the lead a technician reaches for when the machine has power at the outlet and nothing much beyond it.Heat and vibration work on internal wiring year after year. Strands fatigue where the cable is repeatedly flexed, terminals back off their tabs, and insulation hardens until it splits at a bend. What the owner sees is a machine with dead spots: it runs, then stops when it is moved a certain way, or refuses to start at all until something is nudged. Chasing that kind of intermittent fault with a meter usually ends at a lead like this one, and a new cable gives a clean, continuous path instead of a marginal connection waiting to fail again. Unplug the machine before opening it, and note the routing of the old cable so the replacement follows the same path clear of moving parts.
