Dont muck about. Send it back. Ring them and tell them exactly why you are sending it back...also email with all the info....let them sort it out. Muck around too much with it and they,ll find some excuse to say its your fault!
Hi; There may be nothing wrong with your television. What you have not told us is what the voltage is at the battery terminals and what is the voltage at the television. The current draw of the television would be handy as well. Do not rely on the so called voltmeter on the battery case/ box, you need a proper multimeter to measure the voltage!!! You could have a voltage drop issue some were and causing all of your greef.
Is your battery fully charged and just because you battery may show a battery that is above a certain voltage ( 13.7 + volts is good ) and again measured with a good multimeter does not mean the battery is fully charged. But yes you could have a low voltage detect circuit in the television fault , but please do a little homework first and find out what the voltages are before you contact the manufacturer.
Thanks for advice.....Battery voltage (2x 120 full river 1 year old) 13.4 via multimeter... battery voltage at 10 amp cig plug 13.4 battery voltage via bmp mamagement system 13.4
TV is connected to batteries direct. The TV turns on and within 5 minutes or so displays LV warning and continues this warning... no other load on system.
Hi; Yes it does sound like a tv fault and the reason why i asked for what the voltages are is that the service centre will ask the same questions.
One thing i would ask is what type of wire is used from the battery to your cigarette lighter socket. You could have a problem with the wire being under size wire and causing voltage drop. using a meter would not necessary show this problem up unless you were able to measure the voltage at the back of the tv with the set running as this would be the correct way to measure the voltage and see what that voltage is and if there is a difference between that and the terminal voltage at the battery.
When i have installed 12 volt electronics over the years i have always used cable that is rated at around 22 Amps even if it is used for a light load and cable length and voltage drop start to come into play. A perfect example is these Chinese diesel heaters that we all put in to our caravans or sheds. Under size the wiring here and you are going to have issues with the diesel heater not wanting to start and blow white smoke out of the exhaust. Replacing the dc cable from the battery to the heater can make a big difference in the performance of the heater
Regards both questions..... TV is wired to two 120 amp fullriver AGM in parallel, so drawing off two batteries...... Guage of wire 10mm2 or in old terms 10 guage tinned (recommended by auto elec)the run is 1.2 mtrs.....I have not determined whether the actual TV cord from the 10 amp cig to TV may be at fault.... Will test tonight Thanks for questions Cheers
Wire according to auto elec is capable of 50amp draw so is more than over kill....The Cig connection is heavy duty from a specialist 12 volt supplier at 10 amp draw it also has locking tabs... Television is now being checked by Rand Electronics...Which will give me peace of mind. They will be able to advise in due course....Thanks for all the advice. Cheers
You need to measure the actual voltage at the input to the TV while the TV is on and drawing current.
Measuring the open-circuit voltage at the cig connection tells you nothing about the voltage at the TV under load.

Agree.
