How do you solve a niggling electrical problem on your layout? TREVOR JONES presents some tips to diagnose faults and get a model railway working again.
THERE will come a time for every modeller when there is an electrical problem which needs to be solved. Sometimes the fault is obvious, but on other occasions a multimeter may be required to find exactly where the fault lies. A multimeter can be purchased for a little under £10 online from the likes of Amazon and will be able to check voltage (AC or DC), current consumed, for example, by a locomotive in amps, resistance in ohms. In turn it can also test electrical conductivity or find a short.
