2012 r-pod 177 "INTRODUCTION"

Since the two white wires and the two green/white wires are connected together you can think of them as if they are each one wire.

So, all you need to do is know which of those is positive and which is negative. In theory the white wire should be negative and the green/white wire positive but don't count on it.

That is where your voltmeter comes in. Put the meter on DC volts. Stick the probe connected to the + terminal of the meter into the bottom of the wire nut that connects the green/white wires. Stick the probe connected to the meter - terminal into the other wire nut.

If the meter reads in the range of 10-15V then you can connect the black wire from the detector to the two white wires and the red one to the two green/white wires.

If the meter reads -10 to -15V then you know the polarity is the opposite and you can connect the black wire to the two green/white wires and the red wire to the two white wires.

If you don't get a reading in the meter in either of those voltage ranges then be sure your probes are making contact with the bare ends of the wires in the wire nuts and that the battery is connected and properly charged.

When you connect up the wires you should only unscrew one wire nut at a time so you don't inadvertently short out the wires. You wont get a schock from a 12V circuit so you don't need to worry about that, but you do need to be sure no wire gets shorted to another wire or to any metal connected to the trailer frame.

Unscrew a wire nut then twist the bare end of the appropriate wire from the detector clockwise around the other two wires. Then screw the wire nut back on. Tug on all 3 wires to be sure they are well connected. Repeat for the others wire nut.

Done!

As Offgrid indicated you should verify the polarity of your system because the wiring may have been changed over the different owners and the verification is done with a voltmeter.  When you get your voltmeter, as SH indicated plug the red lead into the + side of the voltmeter and the black lead into the - or common side of the meter.  Set the scale to where 12 volts will be read and touch the green/white wire with the red lead and the white wire with the black lead.  You should be getting a 12 volt reading on the meter.  If you are getting a -12 volt reading that means that the positive wire is reversed (in other words the white wire is connected to the positive side of the battery).  Also when I am talking about touching the wires with the multimeter leads I am referring to touching the bare part of the wire (with the wire nuts removed).  While doing your testing don't touch the bare wires (green/white with the white) together by mistake (you will get a spark and might blow a fuse).  To answer your question yes that is how my wiring is connected up but that is after I checked the system for the polarity and read the wiring instruction that came with the analyzer.  Hope this helps.

Thank you...I have one on order. 

+1 to SH Check the polarity of the green/white wire and the white wire.  I just replaced my alarm and I believe that the green/white wire is the positive and yes you can remove the wire nuts (the yellow things) and wire your alarm into those connections.  If my memory serves me correctly the red lead on the alarm is the positive one.  The reason there is 2 wires at the wire nuts is that the 12v run goes onto power something else in the trailer.  Hope this helps

THANK YOU...I will do just that!
