12 Volt Accessory Cable 5-pc Kit w/ SAE 2 Pin Connect

by on Apr.05, 2009, under Accessories

12V Accessory Cable Kit

12V Accessory Cable Kit

This handy accessory kit is comprised of 5 cable assemblies with SAE 2 Pin connect.  The kit includes: 12V Power Port, 12V Power Plug, Battery Terminal Clamps, 2.5mm “male” COAX adaptor, and an 8 foot extension cable.
These cable assemblies can be indispensable.  Coupled with the necessary 12 volt charger, they can facilitate the charging of a cell phone and other electronics.  They can also facilitate the trickle charging of a 12V battery.
The SAE 2 Pin end of these assemblies is meant to be connected to a “power side” SAE 2 Pin connector leading from a power source, i.e., one with a hot (+) positive socket.  In other words, the exposed “male” pin of the SAE 2 Pin connector on the end of these assemblies is meant to be hot (+) positive.
The power port cable assembly, for example, has the conductor leading from the exposed “male” pin of the SAE 2 Pin leading to the (+) positive center post within the power port.   The power port plug assembly, similarly has the conductor leading from the exposed “male” pin of the SAE 2 Pin leads to the (+) positive center post  at the end of the power port plug.
Special attention is required with respect to the battery terminal clamp assembly.  The fact that it is wired similarly…(making it useful for trickle charging, etc., when connected as described above) …makes it unfit for use connected to the output of a Battery Tender.  Here’s why – the SAE 2 Pin connector at the end of a Deltran Battery Tender output has a (+) positive exposed male pin to match up to the SAE 2 Pin of a properly installed Deltran fused Quick Connect…which will have a hot (+) postive female socket.
These are light duty 12 volt cable assemblies, as indicated by the 2 amp fuse integral to the power port plug x SAE 2 Pin assembly.

SAE 2 Pin, 2 Prong, 2 Pole, 2 Conductor – 12 Volt Connector

by on Apr.05, 2009, under SAE 2 Pin

SAE 2 Pin Connector

SAE 2 Pin Connector

It seems “SAE 2 Pin” is the most common “name” I’ve seen or heard given this handy connector, but I’ve also seen and heard the following (or variations of the following): SAE 2 Prong, SAE 2 Pole, SAE 2 Conductor, SAE 2 Wire…sometimes in combination with “molded”, “flat”, “trailer light”, or “trailer type” connector.

SAE 2 Pin Extension

SAE 2 Pin Extension

This is an assembly in which the SAE 2 pin connector is commonly seen – a 12″ extension often used in trailer light applications.   Note that this assembly, being a “true” extension, has the red wire leading to an exposed “male” pin at one end, and protected “female” socket at the other.  Thus, if you have an SAE 2 Pin that you want to connect to…and extend another 12″…the resulting end will have the same “pin” and “socket” arrangement you wanted to “extend”.
This brings up a key but subtle point.  As a matter of practice, if you have a set of wires coming from a source of power…such as a battery…to a SAE 2 Pin connector…the protected “female” socket will be the “hot” (+) positive side of the connector.  A good example of this is the fused “Quick Connect” provided by Deltran with their popular Battery Tenders…which is normally left installed on the battery for ease of battery charge maintenance when desired.  If the “Quick Connect” (or battery “pigtail”…as we sometimes call them) is installed correctly, the protected “female” socket will be the “hot” (+) positive side of the connector.
Think about it…you want the protection from “arcing out” on adjacent metal parts provided by that “enclosed’ socket…rather than have a “hot” exposed pin that could potentially “ground out” and “arc out” on the frame of the bike (regardless of having the tethered cap for protection while not in use).
So…the 12″ extension actually provides what you need to make an SAE 2 Pin “Junction”.  If you cut this assembly in half…you’ll have (2) SAE 2 Pin connectors…each with 6″ leads…and here’s the beauty of this…when you join these two connectors to each other…alas…the red wire leading to the male pin on one joins to the female socket of the other…with its red wire extending in the other direction…a beautiful thing.
This, my friends was one of the recognitions that gave me my start down this road – setting out to aid others in the integration and use of this useful connector.  I thought to myself, this information will be of use to other bikers in their “do-it-yourself” motorcycle accessory circuit wiring projects.  This came after, and as a result of an earlier recognition that both Deltran Battery Tenders  and many portable solar chargers use SAE 2 Pin connectors.  So this is what I’d fondly call a “Paul Harvey moment”…”and now you know the rest of the story”…sorry to hear this gentleman and famous radio personality passed March 1, 2009.
So, you might ask “why are you letting the cat out of the bag with respect to your source of these connectors with pigtail leads?”.  Well, I believe it’s a matter of “value added” – the value I add to this basic component, that is.  I work diligently at being a “search friendly” economical source of these connectors, as well as a source of information about these connectors.  I am more than happy to share what I’ve learned about this connector, and its use.  For some, it might be very easy to find a first hand source of SAE 2 Pin connectors, but for others…living in remote areas, for example…it might not be so easy.  In addition, when I package these “pigtailed” connectors, I make it a point to surprise my customers with the necessary sections of heat shrinkable tubing to aid in making neat installations.  Obviously, do-it-yourselfers could very well have this already, but generally my customers seem delighted to receive a little extra they hadn’t figured on.
I make these pigtailed connectors readily, conveniently, and economically available in 3 different forms – “power side”, “load side”, and as a “junction” assembly.  A “power side” connector being an SAE 2 Pin having the conductor with red insulation – indicating “hot” (+) positive –  leading to the protected “female” socket.  Conversely, a “load side” connector is an SAE 2 Pin which has the conductor with red insulation – “hot” (+) positive again – leading to the exposed “male” pin, as a “mate” to the above.  A “junction” is a “mating” set, including (1) “power side” and (1) “load side” pigtailed connector.
Bohemian Biker LLC makes SAE 2 Pin connectors available in another form, as well –  a higher quality form, actually.  We have an assembly manufactured here in the USA which integrates a larger bodied (lengthwise) SAE 2 Pin connector with approxiamately 11-1/2″  of Black SPT-1 Cord /2-18 AWG conductors.

 The larger size of this molded connector make it easier to manipulate, plus it’s sturdier.  As far as aesthetics go, being all Black is a plus, and the longer length provides some additional latitude with respect to stowing away the wire connection.  Again, I make it a point to include heat shrinkable tubing…in this case…both for the individual conductors…and for the cord (to go over the individual connections once heat shrink is applied to them) with enough to extend beyond each end of the individual areas with heat shrink applied.
Soldered joints are the ticket!  A small butane torch, solder, and a little practice will result in nice secure connections.  Depending on your specific wiring circumstances…you might need to put the wire through the tube of heat shrink beforehand, but make sure it’s far enough away not to heat it up prematurely.  The second layer of heat shrink over the whole cord provides some strain relief, as well as added protection.
Another handy aspect of this Black corded SAE 2 Pin connector is that there is no color coding.  Therefore it can be wired either way…as a “power side” or as a “load side” connector…without violating the color standard.  Although…you don’t have that color indication to keep you straight either!

Using the Bohemian Biker 12V Power Port x SAE 2 Pin Assembly

by on Apr.03, 2009, under Application

In the case of a bike with saddlebags, there is a pretty simple set up that I often use to charge my cell phone while I’m out on my bike.  I use a cable (approximately 12” long) with an SAE 2-prong connector at one end, and a “cigarette lighter” style power port at the opposite end.  I couple the SAE 2-prong connector end up with the matching connector on the “battery tender” pigtail left connected to my Road King’s battery.  Then I plug the 12-volt charger I bought to go along with my cell phone into the power port, and the other end into my cell phone.   There is just enough power port cable length to enable me to put the cell phone, charger, and power port connection in my saddlebag, leaving only a short length of exposed cable.  This set up works like a charm for me, and it has conveniently bailed me out of untimely dead cell phone battery situations many times.

The same set up could be used for charging many other portable electronic devices, keeping the device safely stored in your bike’s saddlebag.   A similar set up could be arranged using a backpack secured to your passenger seat, luggage rack, or gas tank, with sufficient cable length.  If necessary, some sort of conveniently sized bag (made out of leather, for example) could easily be suspended in a strategic location.

The 12 Volt Power Port x SAE 2 Pin assembly pictured in these photographs is what we call our “compact” model, since the body of the power port is relatively short in comparison to most I’ve seen.

Although I’ve experienced no problem closing my hinged saddlebag cover across the cable, I anticipate that will interfere with the rubber seal’s ability to do its job…and in the event of rain, water would make its way into the saddlebag.

When we were developing the design for the 12 Volt Power Port x SAE 2 Pin we have had manufactured, the ability to close a hinged saddlebag lid across the cable was taken into consideration.  I chose SPT-1 w/ 18 AWG conductors (vs. the heavier possibilities…SPT-2 /16 AWG) specifically with this ability in mind.
