Hi all, first post as I'm looking for a little help to a question which I'm sure will be really fundamental to many of you.
I have a plug for an exercise bike I bought and it's of the European type with two pins. I need to switch this for a UK 3-pin alternative but I'm having trouble understanding the polarity, whether it's negative or positive.
As far as I can tell, the terminal which connects openly into the centre within the polarity diagram determines the polarity.
However, some articles I've read focus more on the placement of the '+' and '-' symbols - whether they're on the right or the left. Most show the '+' on the right if it's positive and the '-' on the right if it's negative.
My adapter has the '+' connecting into the centre circle but it's also on the left, so I'm a little conflicted.
Can anyone help?
