Finding Bad Joints In Track Wiring

The following is a method of finding high resistances in track power circuits. The digital voltmeter is set to its lowest range and indicates the resistance in the track circuit by measuring the voltage drop in a given section of track. The movable jumper is connected across individual blocks in turn in order to check each one. A high voltage indicates a bad connection. The jumper must have as low a resistance as possible to avoid false indications Two versions of the circuit are shown. Both work identically except that the second limits the current to one ampere. The tester can be connected as far back in the circuit as desired so that toggle switches are also included in the test. The diagrams show gaps in both rails although this would not normally be the case. The test will still work and might find bad rail joiners as well.
