Fuel cut off r19 td - Retro-Renault

mammy_nun · 21st January 2007, 10:48 AM

Hi,

I've just found this site and need some help. i'm pullin ma hair oot. I have a renault 19 td. It was cutting out and then wouldn't start. I was told it was an alternator problem. I put a direct line from the battery to the fuel cut off which allows the car to start. I have fitted a new altenator but the problem remains the same . Any suggestions?

Cheers

aye its broke.

Obviously theres a wiring/fuse issue between the ignition switch and the stop solenoid somewhere.

Check the fuses then the brown plug inside the aux fux box on the passenger inner wing, the connection can be dicky and melt the plug.

Cheers for the reply,

I found 1 wire that had come loose in the aux fux box, which traces through the bulkhead into i guess the ignition circuit. dont know if this was loose or my investigations have broken an already dodgy connection. I am getting continuity with the connection for the stop solenoid with earth, is this right? I should read 12v at it, I dont think it should also be going to ground. Cars going to the garage today, i cant afford any more time on it. I'm a nuts and bolts man, electrics fry ma heed.

nice avatar chris reminds me of my girlfriend.

did the wire pull all the way out? it may be touchign the shell in there thus shorting to earth now.

It shouldn't go to earth at any point even when off, should just read 0 then go to battery voltage when running

mammy_nun · 22nd January 2007, 12:01 PM

Aye the wire was all the way out, after a bit of research round the site it seems like the loose wire is from an immobiliser(didnt know one was fitted) The dodgy looking bit of mains cable that dissappears through bulkhead and up behind the glove box. I re-crimped and taped it up. There must be a short somewhere cause I'm getting a continuity with earth on the fuel stop valve lead, I thought it should only read 0 and then battery voltage to open the valve.

Could the ECU (black box bolted to bulkhead) be damaged? if so can it be replaced with one frae a scrappy?

**Chris H** · 22nd January 2007, 09:03 PM

the black box is the glowplug relay box is it not?

It doesn't run an ecu as its a mechanical diesel, not the modern EFI diesel.

just a thought, Im not sure what everythin is as I dont have a manual, yet. I'm tryin to eliminate all the possibilities. Do you know where the feed for the fuel solenoid comes from? is it straight from the altenator?

**Chris H** · 22nd January 2007, 09:27 PM

feed will come from the ignition switch or a relay, but I am positive its fromt he ignition switch directly, been a while since I done any 19 diesel work, they are a dying breed.

mammy_nun · 22nd January 2007, 09:52 PM

The mechanic told me its fed straight from the alternator. With the normal feed disconnected and the wire straight from battery to the cut off valve the battery light is always on when i'm drivin.

**Chris H** · 22nd January 2007, 10:13 PM

well if it is fed straight from the alternator it has to go through a relay, as the ignition switch would trip that to activate it

mammy_nun · 22nd January 2007, 10:25 PM

So if there is a relay and its goosed power wouldn't reach the cut off valve. Would that affect the alternator charging the battery? Man I need a wiring diagram. Maybe try the library after work the morra.

**Chris H** · 22nd January 2007, 10:35 PM

it could do, you'll need to do some investigation.

mammy_nun · 22nd January 2007, 10:52 PM

Cheers for you're help Chris. i'll have a further investigation. Once I get a bit of money I think I'll bring it through so you can have a look at it, if you dont mind? I'll keep you posted. In the meantime i'll do the jobs on the Megan.

**Chris H** · 23rd January 2007, 07:49 AM

no problem matey.

Haver a poke about, you may solve it yourself with some luck.

got my td back home today took a reading straight from the altenator. 12.4v does this mean ma altenators goosed?
