Re: Vintage Mazda Christmas lights
Couple of observations:
-Non-contact voltsticks 'voltpens' or similar are particularly useful for single insulated wires like this as the live is less able to hide behind the neutral and create what we call a false negative. On ordinary double insulated mains flex more caution is required.
-The little (ten quid?) blue/grey multimeters from LAP/Screwfix. Reviews of this are variable, mainly since a few of them suffer bad connection where the test leads go into the meter. This should be checked for by shorting the test leads together with the meter on a resistance range and jiggling the wires to check for consistency.
I recently tested two (new) meters of this type, straight out of the box. One was fine, the other one was indeed faulty. The faulty one got binned and the customer who bought the good one ended up with a spare set of test leads!
