Which wire is positive
1173207
If there's red and black then it's red. If it's white and black then it's white. If there both the same color then one should have letters or numbers or line on it and that would be pistive. Sorry been a while since I hooked them up can't remember what colors the wires were.

When you splice them the copper colored wire is positive and the silver is negative

black wire is a ground.. common sense says black is ALMOST ALWAYS negative/ground.

I have negative in the middle, however a 470uf 35v electrolytic measures correctly with positive in the middle also. I mostly use my meter for the badly marked ceramic caps in my collection.

I installed the wire last summer. Used 98+ ft from a 100 ft roll, ceiling mounted Bose 901's. Sound is exceptional. Cable was very flexible and certainly appeared to be all copper. Both positive and negative cable lines are copper colored but the positive is given a continuous red stripe. I have some similar cable used in an auto installation (14 or 16 GA) that is also all copper colored and very flexible. The positive line is identified with repetitive + + + +. It is pure copper as best I can tell.

There is a fuse in the positive side of connection. And a cover for said positive alligator clip for positive terminal. This thing works pretty darn good.

Black is negative 12vRed is positive 12v (can be switched or constant power supply)Third wire (color varies) is supply voltage wanting to measure

It's never a good idea to try to trust wire insulation color as a determination of polarity unless you have a datasheet that clearly states the color and polarity. I always test power supply outputs with a meter before connecting them.

The red wire connects to the center pin, the black wire to the outer ring. As far as polarity, it depends on what being plugged into it. If you want a pos. center pin connect the pos power lead to red. For a neg. center pin, connect the neg. power lead to the red wire.

Just use the low voltage wire from the hareware store. It has the positive and negitive wires together.

First the wiring , brown lead is positive black is negative if you want an automatic system you need a float switch in line on positive side. if you want it on demand wire ground to battery ground and positive through a switch to battery. Bilge discharge is via a 3/4" od semi barbed nipple shon center white plastic part.

copper is always positive. it is possible to switch silver to positive as long as you connect it the same all the way back to the amp or receiver or speaker. Red is usually positive as well. Black being neutral of course. silver is neutral throughout the electronics world. Outlets in walls same thing. Good luck.

Yes you can. Just cut the wire and put positive to positive and negative to negative. Source: I did something similar like that before

There is no positive and negative. It's basically an on and off switch. It will work on ether side. I use it on my Model A Ford to cut the battery off. I put it on the negative side of battery like is "battery-switch-cable to starter and rest of car". Model As are backwards. On modern cars I would put it on the positive side. For the price it works great.

Use a voltmeter. If the needle goes positive then the red lead wire is positive.

The + tag indicates the positive wire and the - tag indicates the negative wire. The wires on the controller with the red sleeves are the + (positive) wires.

Typically the white or dash-dot wire is positive and the unmarked black one is negative. As to the plug itself, the center pin is positive and the shield is negative. Of course, it is always best to test with a volt meter but this is standard electrical wire code.

Make sure the polarity is correct. The negative pin -- Is marked on backside.
