A quick post about a snazzy and useful little tool for the tool box and at £9.99 its not going to break the bank either. The Maplin N48CY current meter will measure up to 20 amps (double most multimeters) and has contacts that simulate a fuse …… simply unplug the fuse from the circuit to be tested, plug the tester in, switch on and activate the circuit – voila, a nice crisp display of the current that flows through the fuse & circuit. I’ve recently run through the Capo fuse block and you can see the table of recorded values here.
