12v Power Port
Revised: 02/07/2003
Introduction:
I wanted to use a portable 12-volt air compressor, on my GL1800, but I did not have a power port (cigarette lighter plug). I also plan to use the power port to recharge my cell phone while I ride.
My plan is to install two power plugs:
- One power port wired to the accessories fuse box and is Hot when the key is set to ON or accessories.
- The other power port wired to the battery and is always hot
Materials:
| Local Boat Shop | Marine-grade 12V Receptacle | 12VRC | $14.79 |
| Advance Auto Parts | 14ga wire 20’ roll | $2.79 |
|
| Advance Auto Parts | Buss ATC in-line fuse holder | BP/HHG | $1.99 |
| Advance Auto Parts | Assorted crimp-on connectors |
The 12-Volt Power Receptacle:
I looked in Wal-Mart, Auto Zone, Advanced Auto Parts, and boat shops for the right 12-volt receptacle. I should rephrase what I just wrote. I was looking for the best 12-volt receptacle for my needs and likes. I say this because I found 12-volt receptacle that start as low as .99 cents and as high as $19.99.
I choose to buy a 12-volt receptacle that is made of corrosion-resistant marine-grade materials and has a watertight sealing cap. The receptacle mounts in a 1-1/8" diameter opening, and uses a threaded locking ring to secure from behind or optional mounting plated to secure from the front.
The 12-volt receptacle is rated at 15-amp capacity, which is more than enough for my portable air compressor.
The Wire:
Crimp-on Connector Color Codes
Color of Connector |
Size of Wire |
|---|---|
Red R |
18-20-22 gauge |
Blue B |
14-16 gauge |
Yellow Y |
10-12 gauge |
I used the wire chart as a reference. The 12-volt receptacle is rated a 15-amps and after routing the wire the longest stretch, of wire, would be about 8 feet, so I decided that 14ga wire would more than adequate. The 12-volt receptacle came with 2 crimp-on connectors, but I needed 2 more. I already had some on hand from other projects.
The In-line Fuse Holder:
To provide protection to the electrical circuits from overloads you must use a fuse or a circuit breaker. There are several types of in-line fuse holders. There are ATC, Mini, Glass, and circuit breaker type of fuse holders. For the power port I used a 15-amp fuse. |

Connection to the M/C Fuse Box:
Connection to the auxiliary fuse block with a master ground block:
This is the most suggested wiring for a power port:
