How to identify which connector is positive and which is negative

How to identify which connector is positive and which is negative

Hi everyone,

ANSWERS:

"@johnny_k

Look on the board where the LED power cable plugs into.

the VLED leads are the +ve leads and the -VLED are the -ve leads

The pin count is shown on the board i.e. 1 down the bottom or on the right when looking at the image you posted and 12 at the top or the left.

So place tester between pins 12 (+ve) and pin 10 (-ve) ON THE PLUG, (which is disconnected from the socket)

Then between pin 11(+ve) and 9 (-ve), then presumably between pin 2 (+ve) and pin 8 (-ve) and then pin 1 (+ve) and pin 7 (-ve)"
