Cobra Remote Switch

Looking for a schematic to build my own remote switch for a high end 1500W/3000W cobra inverter. Any ideas? From what I can tell, simple "shorting" the remote connections together don't work. It must require a bias voltage or other type of AC circuit.

There are 8 40A fuses inside this unit. In the following pics you will see a bank of 4 and another bank with 3 of the 4 removed. I'm currently working on mine as it will cost me more to ship and have Cobra repair than I paid for the unit ($133 to repair). Good luck with your problem

SOURCE: Batteries won't charge on new cobra 2VP 270 radios

If radios are brand new then I would take them back to the store for warranty exchange. The other opton is to vist a local radio service center and ask the tech to jump the battery. if the battery falls below a certain voltage it might need a quick jump sart from a power supply with a higher voltage normally 12 volts works well...

SOURCE: I have a non-lighting Cobra 29 NW face plate, or

that is a power inverter. dc to ac inverter. 13-14volts to 40+ volts ac. to run the el display.. if the display is pulled away from the face like the glue is coming loose that indicates the el display is burnt and will not work unless replace the face plate the el face.. you should have 45volts AC on the two wires feeding into the main chassis face to the el display.

Looking for a schematic or circuit diagram for a Cobra CB radio from 1999 model 25 NW LTD. I can find NW or LTD but not both. Thank you.

The Cobra radio's are pretty much the same for each type. A schematic for the 25 series, 29 series, and others are very similar. The PCB's are generally the same. The only differences are usually the additional features, maybe an extra button or control, etc. The schematics for the most part are the same with the various features added.

The only way that I know this is I have repaired many of the Cobra 29 series, and a few of the 25's and noted the similarities. Many of the boards were manufactured by Uniden and others. There is about a 10 digit part number on the circuit board that you can google. You can usually find the schematic from that alone.

We turned on our generator while our inverter was still plugged in. Can we fix it?

Probably blew either an internal fuse or a diode, open it up, take a look, what do you have to lose?

Cobra 1500w inverter runs for 4 min. and then shuts off with the code OPC.

Is the code OCP?
If it is not the code appearing in the display, then it is not a user code but O does refer to an over tollerance situation and L refers to an under tollerance situation can you clarify?

I have a Cobra 1500W power inverter. The alarm is going off when the inverter is shut off. I drive a truck and have unplugged all appliances from the inverter and the alarm is still going off. What

I can only give some general thoughts on this, I have patched up a few inverters.
Their core parts rely on a component called capacitors these over time degrade with heat which reduces their manufactured value this will mean they fail to fully do their job. The usual result is not providing a smooth supply rail allowing voltage spikes which trip over and under voltage sensing firing off the alarm, more so when not loaded with appliances as spikes can become large.
Your appliances would be snubbing out these through their loading but this can be trouble because they are absorbing this extra energy which may damage them eventually.
This situation will possibly get worse with the inverter failing, it will need a service engineer to work on it or to purchase a new one if there is no local regional repair place.
Look up faulty capacitors in power supplies on the web for an insight.

Hope this helps........

Can A cobra inverter be plugged in to 115AC for DC 12volt output

in a word no!,,,,it cannot and you may blow it up if you hook it up to the 115ac volt supply,,,in side it there is a switch mode power transistor,,that bumps up the 12 volts to 115 volts it only works the one way,,that is 12 volts dc in and 115 volts ac out,,,,

Cobra 29 ltd (1993)

Looking at the schematic TR23 colector ties in with
the power switch ,check D22 it's a 9.1 to 10 volt
zener diode also check C11 an D21.
TR23 shows to be a 2SC1096 I would go ahead and
replace it.Be sure that the CB-PA switch is in good
working order;
Good luck maybe this helped.
