Location: Decatur TX | I have a 1996 4 Star LQ trailer. I am having problems hard wiring my TrailerEyes in. When camera is hard wired I get " no signal " on the monitor but when I use the 9V battery the camera work great, so no problem with camera. Wiring to camera is correct. It seems to be some interference from the trailer. Maybe converter? Any ideas what to check? |

Location: western PA | The trailer is most likely providing 12V, and unless your camera has a voltage adapter or reducer, it may only work on 9V. Your operating manual should specify what is needed when hard wiring is utilised. |

Location: North Carolina | Check the polarity of the input. The camera expects positive on one terminal and negative on the other. If it's reversed, there's no joy. And maybe the release of smoke. |

Location: North Carolina | Also check the adapter output at its jack. It should be 9 volts. Just like the battery cable jack. If it's not, (and the 12 volt polarity is correct) the adapter is faulty |

Location: Decatur TX | The trailereyes camera can be used with either a 9 V battery or with 12 V. The polarity of the plug is correct. we checked out the camera on 12 V in a friends trailer and it works just fine, it is just not working in my trailer. We think there is some kind of interference coming from my trailer. Just not sure what to check.

Location: Decatur TX | It is not the wiring to the camera and it is not the antenna. I connected the powerline for the camera to my tractor which is sitting next to my trailer and the camera work just fine.
The problem is IN the trailer.
It could be the converter in my trailer since this trailer is a 1996 or maybe it's a grounding problem. Everything else in the trailer works fine. I believe there is a interference that is keeping the camera from working, just do not know what to check |

Location: Penrose, Colorado | are you for sure that you have power to the camera ? when mine is turned off the monitor in the truck will say no signal.. it has to be the wiring or converter. |

Location: Decatur TX | I have 12 V on the inside of the camera plug and negative on the outside of the camera plug. There is no problem there. Yes, it is turned on
The converter seems to be working properly on everything else in the trailer |

Location: North Carolina | Wait ... When you use the 9 volt battery... is the camera in the same location as when you have it hard wired to the 12 volt supply?That's my assumption. Remember a metal trailer is a very good block to radio signals. |

Location: North Carolina | Are you getting the DC 12 volts from a converter or a battery in the trailer?Some converters supply a chopped wave form. Batteries and lights don't care, but electronic devices don't like it. |

Location: western PA | If you are getting interference from another electronic device, the camera's power supply can be upgraded with a co-axial shielded cable. The outer mesh covering is grounded, and the camera can be grounded as well. This is a common solution used with aircraft avionics, to suppress outside interference. If your trailer has the original converter, it may not be designed with regards to today's modern electronic devices. Just as with inverter generators, the new converters produce a much "cleaner" voltage, that is critical in the operation and usage of modern electronics. It might be interesting to compare the specifications and age of your friend's converter, that allows your camera proper functioning, to yours. It appears that you have eliminated most of the possible problem areas; the only remaining reasoning would include the power source. |

Location: Decatur TX | I can not change the antenna wiring. Is there a wire that can be run from the battery to the camera that has a 12v plug that would suppress the noise?
Would I have the same problem if I added another battery that does not connect thru the converter. It would be grounded to trailer |

Location: Vermont | So what input have you gotten back from Trailereyes? Have they offered to send you a replacement camera to determine if the 12 to 9 conversion is bad in your camera? |

Location: Decatur TX | The camera works fine until it is on 12v in the trailer.
There's is signal interference from the trailer, probably the converter that I don't know how to fix without replacing converter |

Location: western PA | Using an aux battery not connected to your converter would give you a "clean" source. |

Location: Decatur TX | I wasn't sure the battery would be "clean" since it has to be grounded to the trailer.
Thanks gard for the help |

Location: North Carolina | You don't have to ground the 12 volt battery to the trailer. You can keep the 12v battery isolated from the trailer and only connected to the camera through its adapter. You'll have to charge the battery separately. Or ... do not use the converter when using the camera. A battery supplies the cleanest DC power. Even a regulated power supply has more noise and ripple in the power than a battery. |
