 |
|
Is there a convention for which of the 2 terminals in an Aux/cigar lighter port goes to + or -? I'm currently wiring my Aux power socket and wondered what everyone else does. I can't seem to find anything definite on whether to wire the centre pin or the outside pin to the +. Does it actually matter?
Thanks in advance.

Yes it matters. Center pin is positive.
You'll note that the pin that is off-center will be shorted to the case of the receptacle, which in turn would be shorted in the panel. You would quickly know you wired it wrong.

Thanks Alfio. Good job I checked. It never ceases to amaze me that these things can be produced and not labeled, assuming that everyone knows what they're doing - clearly wrong in my case!

The standard convention is Positive + to the centre pin and Negative -
to the outside body or pin,
Yes it definitely matters!
