[Solved] Renault Scenic 1 dti 2001: Glow Plugs Not Heating, Red Cable Supply Relay, Fuse Check, Burn Out

Hello, I do not heat glow plugs in Renault Scenic 1 dti 2001. There is no power on the red cable
supplying the glow plug relay. Earlier I wrote that everything I could check was fuses. I will add that when I gave the current using a separate battery cable for this cable, the candles heat up. I don't know if I can leave it this way. I am asking for advice, what else can I check. And could this cable burn out? I am sorry that I did not describe this problem the first time. Thank you for all advices in advance.

Look for a large fuse under the hood, probably 70A he is from glow plugs.

Hello. Here's the diagram.

Hello, the fuse checked, I even bought a new one. Nothing more. Could this cable burn out, or
has a break. Should have some resistance. how can i check it without ripping the installation. Is there
four relays maybe they turn on the current. I am asking for advice. Thank you

What is your power 72 or 59kw ?.

70A fuse goes this red wire to the glow plug relay. Remove
fuse and check the passage meter.

I have the same problem with the fact that I have current on the controller from a 12.6 V battery is the transition from candles to the controller after turning the ignition comes current to the controller 111.6 but I have no current on the candles damaged controller or some temperature sensor or maybe something else

The glow plug light comes on ?.

There, the fuse is on Aku, but I've already replaced the power cable to the relay twice.

This is how the glow plug indicator in the car lights up.

I have electricity on the relay

Try to activate the relay and check if there is electricity in the candles.

You checked this power cable with a minimum 55w light bulb, if you found it with a meter.

I checked the 10w meter and bulb

Check with a more powerful light bulb as molasses colleague wrote.
You did what I wrote in the 11th post ?.

Somehow I missed this post and yet you can easily check at least under the load of one candle
I bought the driver but that's not it
Now I checked everything calmly, I redirected the current from the (+) constant on the controller to the individual four candles and on each of them the 55w lamp was lit as I put on the candles and connected the meter was about 11.6v
But by measuring the other two wires from the ignition, on one I found mass lasting a few or several seconds, and on the other meter I measured 11V current that lasts as much as the pump from the fuel only from this current I did not want to light even a small light bulb

I have no idea why but I tried to turn on the + and - driver from the battery and it failed and the driver has a new original
Of course, I connected via a light bulb

My problem of not heating the candles was the burned cable leading to the glow plug relay from the fuse box under the hood. Subject closes the problem solved
