How do I get this to turn on (without wiring to the car). I just plugged it into a 12V ac/dc adapter that I know works. I don't see any signs of lif

Just plug the monitor to a 9V battery that you can buy from the Dollar Tree. Red wire to the positive and black wire to the negative. Use one of those "TV GAMES" joysticks with the built-in games to test it. I tried it yesterday and it worked great!

The screen will not come on unless there is a powered camera hooked onto it!

Make sure ur AC Adaptor or Battery can Supply 12 volts and at least 400 Miliamps and u hav an Active Video signal Transmitting to the monitor. the monitor automatically shuts down all circuits cept the video processor to save power wen no video is present but wen a video signal is detected the monitor will turn on the Screen. this is a nice feature as i plan to use it as a remote Viewfinder for my Camera.

You have to have continuous power going to the red lead and on/off power going to the white lead.

I had the same problem with my Raspberry Pi and when I read this I realized that my config.txt file was overriding the video out port! Few!

Mine is connected to my camera and 12 volt battery and all of the power and ac/dc cables are plugged in but it won't work.

Make sure your video is plugged in....I use a 12 v. adaptor, mine works fine

As per other answers, need active video signal. - This is a designed-in feature for the rear view/license plate camera application, not a flaw, as a screen saver, power saver or distraction saver.

I had a professional install it for me. I would have to say it's from the battery and I can also remove the fuse that it's attached too. Mine is on my hood almost like the Knight rider (G6 GXP version). It only turns on after you start the car. I am sure you could have it wired to some alternate battery pack too.

it has to be plugged into a 12v dc power source, like your car cigarette lighter, or with the direct to battery connections supplied with the inverter. it will not work unless it is connected to power.

Yes! I just went out to double check. First I plugged it in the wall. Then I plugged it into the cigarette lighter. The red light came on the element plugged in the wall, when I plugged into the cigarette lighter. You may have to wiggle it a bit in the cigarette lighter for the red light to come on. That's not the case for my car here, but I have another one where it's necessary to wiggle it a bit for the light to come on. Unless the light comes on, it's not charging. That would be my take on this.

It needs a 12volt source. I ran it off of the ignition fuse in the fuse pannel on the drivers side. Only works when the ignition is on. I put an inline fuse as well. Very simple.

To test whats not working properly, check polarity and connect straight to battery to test horn on its own, have heard of problems but have had none myself. Must run off of the relay provided and I made a direct connection to battery for the horn from the relay, the other side of the relay to the old horn wires. Did your old horn work?

I had the same problem. Used this unit as portable power during power outages, to charge phones etc., and it works fine for that. First time I tried jumping my car (with the unit fully charged) it didn't come close to turning over the engine. Jump-started the dead car from my other car with no problem, though. Yes, the power was switched on. Very disappointed that I can't keep it in the trunk and rely on it to get me out of a jam.

I purchased mine as a spare and have not installed it yet. I looked at the hookup before buying, if not a link via the Amazon site, it may have been on the Grote site. Is very simple, but you do have to locate a hot wire that is ignition switched to turn the power on and off. Rich

Many OEMs of these don't recommend changing the battery (for liability reasons), yet there are batteries available (and places like batteryspec.com have a search set-up based on brands of these "jump-start" packages where they'll tell you what fits). They are typically AGM sealed batteries and "deep-cycle" since running the inverter or such for a long time is putting it thru a "deep-cycle" of draining, then recharging. Before ordering a new battery, I'd do some tests on the existing one. With it plugged in for charging I'd check the battery voltage (on the jumper cable clamps with them turned on). You should see at least 13.5V or ~14V is better to hint that it is full (but you don't want to see 15V or higher). If it's less than that, it's not really charged and maybe the charger isn't working (which would make me try charging it by another way including from the car before further testing). Once it is charged, then I'd unplug the charger and see what the voltage is, it should drop to ~13V, but not below ~12.7. If the voltage is low, I'd try charging again, but if it instantly shows 14V while charging (and I'd given it at least an hour charge time before) then I'd stop charging and proceed with the test. Next I'd try running something off the battery like a work light (that can run off the inverter or 12V). The battery should drop to ~12.5V instantly while running the light and if you keep it going it should slowly drop like after 5 minutes down to 12.4V, after another 5 minutes 12.3V, etc. If running the light drops the voltage to 12.25V or less instantly and after 5 minutes drops to 12.0V or less, that hints a bad battery. That should tell you if it's really the battery or perhaps other issues (like charging).

There should be a plug that comes with it so you can just plug it into the outlet in your car. Mine did anyway...

Maybe this will help I hook it up to a 1993 chevy truck I hook the voltage wire right to a ignition wire 12 volts in accessory and 12 volts with key on the same wire test with a test light to find the right wire. the voltage measures my battery voltage and when running my charging voltage no problems. I bought the three in one meter voltage temperature and time you can isolate each one or have them all read showing individual readings intermediately so yes it's can read its own power but it is powered by your cars battery I hope this helps you. Ps I'm a auto tech for 37 years now. I Had some problems with the temperature sensor probe but they sent me a new one seems to work okay now. Just so you know it comes in 1 gage not 3 that's just showing you what the gage dose.

There is no "plug" it has two bare leads, that can easily be spliced (you could attach to a 12V "power port" plug for car cigarette lighter if you want). Any 12 DCV will work (and up to 24 DCV I guess, I haven't tried that), with a current draw of just under 1 amp it is very bright white flood (you don't want to look straight at it). I have this installed in a cabin with 12V (Marine Deep cell) battery for lighting our "living room", and works very nice. Just make sure that you have the positive battery terminal on the red wire. It does emit some RF interference, so a weak (radio) station will have a buzz if receiver is close by.

Rarely are these things under represented as to features, but this one is. I just bought it, and the specs say it runs on DC from the car, but they don't say it includes an AC adapter, which it does. You do not need to purchase that.

It requires the AC power supply. I suppose you could plug it into an AC/DC converter and plug that into your cigarette lighter, but at that point I think you are getting more complicated than it's worth.

If you don't know anything about electronics, maybe this isn't for you. You can cause problems for your car if you do it wrong. What I did was to find the wires to the cigarette lighter and connected the red wire to it and ground the black wire.
658471
Same thing happened to me. Unplugged it until it turned off. Plugged it back has been operating normally. You need to protect it from excessive heat when the car is parked.

Do you have one of the cars that require the key/engine on to power the cigarette lighter? Check and reset your auto fuse/breaker. If not tripped then bad contact/wire break somewhere. After that I have no suggestions.
