BRC Gas Indicator Off: Car Won't Start - Possible Fuse or Cable Issue? Button Replacement?

I have a problem with the car, today it fired normally I went somewhere I left the car for 2 hours I come back and it does not start; starter, fuel pump are working.

The BRC gas indicator is not lit at all, I tried to press the button on the indicator but it does not change anything. I unhooked the button and plugged it in again
no reaction. I used to have a similar problem that the light was off but I got there and then the problem fixed itself.

What could it be ? Maybe the light - the button is dead and you need to replace it with a new one? if so, it is possible to fire only by connecting the appropriate cables. The question is which cables should be connected so that the car starts on gas and which are responsible for the ignition on gas?

In the evening or tomorrow I will go to check the fuses in the car.

The first one I hear is that the car fires up by connecting the appropriate cables. It's just a mate indicator

It is a button with LEDs, using the button you can switch to gas or petrol.

The question is why it does not light up at all, maybe it is broken, so I am thinking about shorting the cables, but I do not know which colors to shorten.

Oh yeah. I'm sorry, I read it wrong.

The gas control unit has no power and that's it - leave this button alone.

So I have to check if there is power on the cube, if the power is on, it means that the button is broken. Only on which cable to measure the power in the ankle - black and red, I think.

If there is no power, where to look for the cause? First I will check all the fuses under the steering wheel.


The most important question is what to do to make the car start on gas so that I can go anywhere.

No, you don't have to do anything - get this car to some electrician before it bursts into flames. You have no idea what it is about. It's not the button that's to blame! . The LPG control unit does not get power. It is plugged into the "15" circuit somewhere after the key - probably something burned / oxidized somewhere, since it does not burn on petrol.

I checked the voltage on the ankle entering the BRC DE817010 gas controller.

The cube has 3 rows of contacts with 8 contacts per row. Row markings A, B, B.



The red cable is connected to the pin in the 1st column of the 3rd row as marked red in the figure,
From him, I measured the voltage to all other contacts and on each contact except the marked ones
in Figure Ov i 0.05V was the voltage value as on the battery, i.e. about 12V + -0.3V




Are these good ankle tensions?

In row A, cables 8 and below it are broken at the engine, but more on that below.


After connecting the driver under the mosquito and turning the key, there is still no voltage. So kind of
there was no more tension from the hood to the cabin.

I checked if there is a connection from the red cable from the cube from the controller to the red cable from the switch cube and there is a resistance of 800 Ohm, i.e. there is a connection.

Speaking of the cables from the 8th cube, I don't know why, but they are broken and not insulated.

I have not yet checked if there is a fuse in the wheel where I have a toroidal cylinder.


What's next gentlemen? Is it possible to switch to petrol manually? Is the gas engine able to do it quickly so that I can get to Poland on petrol and I will have this problem there?

Car on a tow truck and to the nearest electrician until it burned out. You didn't even bother to find the generally available Squent 24 installation diagram, you just stuck your hands on the proverbial stick wherever it falls. There is no plus after the ignition switch, taken from the power supply of petrol injectors - white / brown wire to the gas unit. So either the above-mentioned cable is broken, or due to some damage to the vehicle's installation, no power supply to the injectors - which is most likely, since the car does not use gasoline.

And that could be the cause of the robocop. I started looking at the old photos of the engine that I took after buying the car because I was curious how it looked with the broken cables and the two cables: white and brown in the old photo go under the plastic housing on the engine. I'm going to unscrew the casing and I'll probably see the rest of these cables, connect them and insulate them. This plastic casing has a sharp edge at the bottom and the cables were taut so this edge of the casing could "cut" them after some time. As you wrote: "There is a plus after the ignition, taken from the power supply of petrol injectors - white / brown wire to the gas unit." and it would fit.

Added after 3 [hours] 54 [minutes]:

Ok, I took off the plastic housing of the motor and found the broken cables there, twisted them and insulated them, I need to solder them well. Now works as it should also robocop do not panic that the car will burn out. This elektroda.pl is for people to help each other. Subject to be closed.

For the tow truck and repair, I would probably pay a total of 300 EUR.
