That's the burnt leg on the green relay, that probably among other things, gives power to the boot popper, heater fan and most importantly radiator fan!


FRST owners: Drop the fuse box (take out the 2 screws holding it into the dash) and drop the fuse box out exposing the relays. The only green relay in there is the one that seems to cause problems and so remove it and check the legs (if you're having problems with the fan not working etc.).

Cheers,

Andy

is that relay found on 2is and the RS's as well?


Thx

I'm 100% certain that it would also be on XR2i's - so worth checking out mate.

Tony told me that the fire in his car appears to have started from the fuse box - and looking at mine it's actually melted the plastic in the fusebox that goes around that pin (pin numbered 30 on the green relay).

Also, when reconnecting the relay you may want to stick in a small flat headed screwdriver to scrape the contacts clean so that it makes a good contact. I stupidly put the fusebox back together after straight plugging it in to find it wasn't making contact meaning I had to take it apart again and clean it! WD40 on the relay contacts always helps to make sure it's a good electrical contact.

HTH,

am i right in saying that this relay would only be found on frst's and 2i's?

thanks in advance.

I'd imagine the Si would use the same relays too but I've got a feeling that the RST suffers worst due to high current draw from the fan (turbo's always run hot due to hot turbo and small engine bay).

Still - for peace of mind it's worth checking just to make sure.

BTW - the relay cost me £10.20 including VAT from Ford (a bit expensive I thought).

I dont remember seeing a green relay on either an 8v 2i or Si fuse box.

Will be having a look at my Si to check either way after seeing what happened to tony's

[Sams Si]

cheers guys, ill be having a look this weekend

No probs Andy, i knew it would be that.

Yeah scraping the contacts clean is the right thing to do, to ensure a good connection - it's not uncommon for the fuse box to melt slightly around this area when the relay goes. You might want to consider checking the relay and replacing it when the leg starts to look burnt, or making it's life a little easier

You can hard wire it away from the fuse box, or alternatively, mine is in my fuse box, but only does the interior fan, front fogs and boot popper - i've removed all the stress of it running the engine fan My fan now runs from it's own relay, wired in series with a second relay, providing ample power for my fan

my radiator gave up this week, when i tried bridging the connection the fan still didn't work, do you think it might be the relay? my heater fans and boot pop are all working ok???

Chris

[FezzR]

very common problem that been known for ages im supprise so many people are still suprised by this

[welsh_frst]

sorry radiator FAN i meant, so if the relay has melted would it still work for the heater fans and the boot pop ?

Chris

[welsh_frst]

just pulled the fuesbox out and the relay looks fine so its defo the fan, only trouble is finding one, got quoted £200 from ford to day, a mates hopefully got one in his crashed festa if its in one piece that is

Chris

More likely to be the radiator fan switch.

[MFkev]

yeah I had this problem so many times now. I've had two new relays in just over a year of owning the FRST.

Plan on wiring the cooling fan to a seperate relay, had the water temp in the red twice now cause of this realy.

P.S I've got 2 green relays

[enve19]

The green relay as shown above is also present on the 8v 2i

[welsh_frst]

i don't think its the fan switch- is the fan switch the sender attached to the thermostat housing the the multi plug isn't to clever but i've pulled the plug of bridged the two wires on the plug and no joy, i 've tested the plug with a multimeter and theres power going through it so theres defo power to the fan so must be the fan.

Chris

[t2rst]

im gonna check mine the week end as wen my fan comes on it seems to take most of the power from everything else would this be relay related or is it just [ERRR] it draws shed loads of ampige


cheers



dave

i think ford are gonna run out of relays soon with everyone replaceing them because of this post

[xfactor]

Fan switch is in the Radiator or in the bottom hose on the fiesta usually, ones in the thermostat are for your dash display and ECU feed.

[welsh_frst]

i dont think there is a switch on the actual rad doesn't say in the haynes book, there is a single white wire just to the left of the thermostat i know thats for the temp gauge, will go and have a butchers now,

[xfactor]

Could be me thinking zetecs, Its all I seem to see these days, worth checking out though

[welsh_frst]

gonna check now, i know the cossies have a sender on there rads!

8v 2is do have this rely [ERRR] ive got one on mine. I had the same probelm with the fan etc it also knock out your heaters.

Hi Andy

I have a mk3 1600 rs turbo that won't run.

When it was running as soon as you put the heater fan on, or selected reverse, the car stalled out, so £15 later from ford the ignition relay has been replaced.

Everything worked fine for a day, then the same problem came back after the car stalled out again, and the reverse stall and fan problem returned. - I am now wondering why the second relay would blow. The car has a new alternator and battery, has good earths.

I purchased a relay or 2 off the internet, check the numbers on the relays were the same, they are and tried the internet purchased relay and I cannot get the car to run at all. The car used to run with the old relay in place, unless you turned the heater fan, or selected reverse, which was inconvenient but still usable. It now won't run at all, and I have spent hours ensuring all 5 pins had a good contact, even though they are now bent a bit, and tried both relays to try and coax the thing back into life, but to no avail. There is no melting of plastic or signs of any burning etc.

My questions go.....
How do you test if the ignition relay is in good working order? I have a multi-meter, and can use the battery for a power source

From the fuse block, how do you remove the wire connectors and pull them out,they look like normal crimp connections, but have crosses cut in them not just a single slot as they are going to get straightened or replaced, to ensure a good clean contact, which may be causing the problem.

What else should I check?

Please send a reply asap, as I am meant to be using it for transport this week.

Thanks Andy
