I wired a cigarette lighter with a spring cap to my bike.
I figured I could plug in my Garmin GPS via the same plug in I use in my car.
It is not working.
I even cut the wires to the ciggy plug in and touched the wires directly to the battery and it would not work. I then tried to use my car plug in, I plugged it into the ciggy plug and directly touched the battery with the bare wires and ...nothing.
Could it be the cigarette lighter plug? Or the device I was trying to plug in?

 

Are you sure you have polarity correct?

 

Seems like a similar prob someone had a while back, check the polarity of the wires, ac makes no difference, but dc is a different animal.

 

Well, I assume your battery is good? Then if the devices, which work from your car's lighter, don't work, then its the lighter (if hooked directly to the battery without a fuse - but I would always use a fuse to protect your devices).

 

You have an "Open Circuit" in either the Red wire that goes from the Positive "+" terminal of the Battery to the Center of the Cigarette Lighter, -or- the Black Wire that goes from the Negative "-" terminal of the Battery (or any Chassis Ground) and the Side of the Cigarette Lighter. My # 1 guess is that there is either no fuse in the fuse holder in the Red wire, or if there is a fuse there, the fuse is blown. Guess # 2 is that one or more of the wire crimp terminals on the Red and/or Black wires is not making contact with the wire. In other words it is crimped to the insulation not the wire itself.

 

get yourself a small volt meter that will read dc volts ... that will tell where you have and dont have voltage

 

If you have DC voltage (meter or test light) at your plug in and device does not work. There is a fuse in the plug in end of the device.

 

Has there been any recent nuclear device detonations? Hey! dont get on me, thats what Haji at the help desk asked....LOL

 

I would presume the cigarette lighter works on the bike?

 

Well in and amongst everything else that has been mentioned.... If it worked prior to plugging it into the bike you may have blown the fuse in the "GPS cig adapter". Most if not all have a glass fuse in the plug. Unscrew it and dbl check that. If it's blown your wiring on the cig lighter is wrong. JMHO.
