fan question...

[funinthesun]

now this has happened a few times lately, when I turn off the car , (and there is no relation as to how long the car was on in the first place), the fan comes on.

if I put the keys back in and turn to position 2 it stops. and is then fine.

now this is not a major problem , but appart from giving me the option of a nice breeze as I walk out of the garage seems to be a bit of a glitch...any ideas what might cause this and ifs it even worth attempting to stop it happening.??

thanks

Had this on mine and it was put down to a dirty relay. Had the car serviced and they squirted some electrical cleaner on the contacts and it's been right as rain ever since. In the mean time I had to remove the fuse to stop the fan!! luckily not going on any long journeys and watched the temp very carefully (but was literally days away from its service).

Change the relay with a fan overide plugged in.

[tamago]

maybe previous owner put in a fan relay after engine switched off and you triggered it?

why david?no need for an override for this problem,if in doubt you would just replace the relay. on the sales pitch again are you? i really get pi$$ed off by seeing just how many replies you make,where your only real concern is seamingly a thinly disguised lead to a sales pitch.ive written to you a couple of times with regard to electrical problems,and your solution is always to buy something off you and not details of how to solve the problem.the whole point of this ph forum is,i thought,for people with a common interest to help each other with impartial honest advice,people with nothing to gain but the pleasuse in being able to help others from past experience gained.using these forums to advertise and promote your business is,i thought against the rules isnt it?why cant you give a constructive opoinion rather than a lead to an advert or sales pitch which the vast majority of your replies seem to do?ive also found that the components of your kits can be purchased in quality form for a fraction of the price you charge,and the know how to install them is readily available(usually from ph members)and is easy for most people to carry out.so please GIVE IT A REST!!YOUR SPOILNG THE FORUM.p.s. also like to add that i know im not on my own in thinking this,having spoken to several others on the subject.

A bit harsh mongoose? Been looking through David's posts to see what you mean but can't see any sales pitch.

[PetrolTed]

Lighten up Mongoose. That's a common response to cooling issues and I don't think David was overtly plugging his goods.

Personally moongoose I don’t' think he is, and from reading all the posts shown in his profile I can't see where your coming from. But in fairness I have not read all 581!

IMHO I do not want to get into personalities and I also do not believe that open forums are the place to direct your anger a fellow P/H'ers

I would request that you please edit/moderate the content of your thread.


I would like to add that I do not personally know david beer.

if you cant see the leads in the following threads then theres something wrong! just read'stupid glove compartment latch' 'why wont it start' and 'ive got it-a few questions from a novice' and these are only the ones currently left on his profile.there have been many others in the past.ive nothing against david as a person-i dont even know him,but just get fed up of him putting sales leads in a thread instead of constructive comment.the above reply from david is a classic,no explanation as to why to fit a relay with override switch and its not surprising either,there is no need for an override switch to stop the fans coming on in this case,why not just say 'try changing the relay'!!hes just trying to sell his kit.from past experience,he then e-mails off line with an advert!(if you havent swallowed the lead and already asked where you get them of course).i just think its not right to let this happen.you dont let leven technology for instance do it do you?id love to see ph stay as an unbiased public opinion forum and not get abused by unscupulous plugging/advertising just as your rules suggest.

Steve Heath pops up with lots of technical advice from time to time, some of it obviously needing specialist attention - is he plugging his books, then?

I have been asked several times for medical advice - I give it willingly, but no-one's ever sent the 50 guineas I asked for!

Lighten up a bit, mongoose, old chap.

exactly nubbin youve hit the nail on the head.steve heath gives you the advice you need,and doesnt just try to sell you his wares.and you give advice willingly without trying to sell something.i dont try and sell one of my battery conditioners everytime i read an article on battery/starting issues do i?anyway ive said my peice and made my point.lets let the thread get back to its original topic,cheers-mv

[ray_von]

i agree with you mongoose on both counts but then again are you trying for a free plug for your own wares

[ribol]

Maybe the point Mongoose is making is that there should be one set of rules for EVERYONE to stick to, not the chosen few? Can't see anything wrong with that point.

I don't see anything wrong in PHers suggesting their company's remedies when the subject arises through a genuine topic - we're all adult enough to make our own minds up about how we respond. David's been a great source of useful advice to me. As have Shpub, 2Sheds, jamer, etc., etc. Long may it continue - that's part of the attraction of PH.
Nubbin - my right foot's big toe is sore and swollen - can you suggest a remedy - if your emedy means not driving my TVR for a day or two I'll just have it amputated. Where do I send the 50 guineas - pigs that is?

PS Let's get back to the topic. If the fan just stays on until the temperature drops and then switches off then this is probably a deliberate alteration done by previouis owner. Have you let it run on to see if this happens?

David hasn't come back to defend himself yet and in some ways I can't say I blame him. If you had a go at me like that I'd be tempted to say the lot of you, why should I give up my free time trying to be helpful if this is the thanks I get? David helps because he is an enthusiast, just like I am.

I've never actually met David but I've spoken to him in the past and he's given me very helpful advice - as he's trying to do here. I think it's fair to say the reason David is producing these cooling upgrades is that they do solve some common problems. Hence you will find them being mentioned from time to time, by David and others, when people ask how to solve these problems. If this thread is an example of the ones you object to, I think you may be missing the fact that David's answer is not exactly hard-selling his fan control system, and does actually address the problem. If the relay is sticking, you need to get the fans to come on (if you have a fan override then use that, and I recommend fitting these anyway, but if you don't have one you can short the otter switch or run the car until it gets so hot the fans come on). When you switch the engine off, this removes power from the otter switch circuit that is supposed to control the relay; if the relay stays on it is almost certainly a stuck relay. If you then pull the relay, give it a tap and put it back it will normally release. If the fans stay off when you put it back this is very strong evidence that the relay is at fault. You will need to replace it. You need to replace it with a new one with the correct rating. If you don't know what the correct rating is, I'm sure David would tell you. If you use the wrong rating it will tend to overheat and suffer exactly this sort of problem. Obviously, it's possible the existing relay is the wrong spec hence the probem. You also need to check the state of the relay socket in case it has suffered heat damage, and look for signs of an overheated terminal from a loose terminal.

I understand why you might feel hostile to somebody who came to Pistonheads primarily to promote their own goods and services. But I think you need to bear in mind that the experts who are best placed to provide help are often in a related business. If the best answer is to go get the right parts or get some work done, and they can supply the parts or do the work, are they wrong to mention this? IMO Pistonheads benefits immensely from the technical input of Tim, Mark, Joolz, David and the like and we should be grateful they are willing to help us.

Any luck with fixing the problem??

Can we have a few more details? Do you have one relay/fuse set up? Are the cooling fans on when you pull up and continue, or do they come on when you turn off? Do they always turn off? Will they go off if you pull a lead off the otter switch? Its just that the supply to the relay is "live" all the time, its the low current side of the relay that should be switched through the ignition switch. Nothing else stays on that normally would go off with ignition? "And finally Ester", are you sure its not the fact that the otter has just turned on and someone has modified the relay so it does this? A simple test would be to simply replace the relay and see if it no longer does it.Something that is confusing is the fact that you can stop it by turning ignition on and then back off, umm.
