If you are thinking of using it for motor stall checks then it needs to be 10A capable on DC. You only need around 2A but 10A is the standard on meters, else they are only 200mA capable and any motor in series will probably blow the internal fuse.

Three of us spent yesterday dismantling a tractor after I was given decorating leave. I was the youngest at 69 3/4.


I bought a meter from Bangood. Seems fine and only cost a few quid.

I am pleased that you are doing well but since I learned I have Pulmonary Fibrosis in 2016 my life has changed and sometimes am weak as a kitten these days. Not easy to explain. But I cant do things I used to but can manage most even at slower pace. You know I was working on my trailer yesterday putting new lighting board on it and new towing hitch that took me ages . 3 years ago would have had it done in 20 minutes. But life is good. :P :P Just bit slower :)

What John is referring to measuring the current drawn by a motor when it is stalled; a recommended requirement for fitting a dcc decoder so you know what amperage rating a decoder has to be, although usually you can find dcc fitting articles on the web for any particular model / motor which will recommend a decoder so you either use the same or one of equivalent amperage rating.

Stall check - see Brians main site for how to do it, but essentially it is a DC check carried out before choosing a decoder rating.
