Title: Glove liners - plus/minus - electrical question
Post by: stopintime on March 26, 2012, 02:54:00 PM
One harness - another liner - mixing and splicing harness components....

If I cut my harness, I have two pairs of wires. Plus and minus in each pair.

I don't know, but I assume it's best to have the current flow the same way in both liners....

Holding a multimeter in my hand - what's the next noob step to determine which wire is plus and which is minus?

With harness plugged in and power on, measure current from wire ends.  if volts are +, then the wire with the red probe is hot.  If volts are -, then black is hot. 

Alternatively, you could plug it in and see which wire has continuity to some other ground on the bike.

Thanks  [thumbsup] ... and if the wires, going into the glove liner plug, are not identifiable... I can probably do the same thing with the plug, while the wires are temporarely spliced (?)

I am assuming you have a harness for the liner and a separate harness for the gloves, but you only want to have one harness installed on the bike.

I would measure continuity across the plug (from harness to the cut wires where the glove used to be). 

If you do not have a bike harness for the gloves, then it seems to me that standard practice for the "bullet" type plugs is to put ground (-) on the outside so you don't accidentally shock yourself.  After you cut, you can measure continuity from the outside of the plug to identify the - wire.

Old harness - wrong plug for new liners - getting new plugs on a piece of wire, from the liner manufacturer.

Your advice will help me get it right - thanks [thumbsup]
