KZN185 How to adjust the glow plug timer?

[MattF]

No.

Tell us! Tell us! Tell us!!!!

I'm not telling, so there.

Glow Plugs AGAIN

I am sorry Matt but I think you are barking up some other tree.
Switching the ignition on/off. on/off within 20 seconds or so with a cold engine will not do any different from switching the ignition on and leaving it on for 20 seconds as the plugs will remain fed for up to a couple of minutes even after the engine has started (this is with starting a cold engine).
All you do with the on/off routine is reset the timer and heat the plugs possibly over the time limit.
I do not think Toyota have designed a system where the key has to be switched on, off, on , off to get the correct heat in to the plug for cold starting.
I have checked the forum as you aqdvised and cannot find ANY information indicating that there is any good to be gained by the on off method UNLESS there is a fault in the timer relay which goes off as soon as it gets power.
It is not possible to go by the Heater Plug indicator light, as it DOES NOT show how long the plugs are being fed for, the light may as well not be there as it only shows the relay has been fed and should now be doing it job.
This is why I fitted a permanant indicator lamp to the feed rail so I could tell when and how long the plugs had been supplied.
If you know something we have all missed it would be the nice thing to do and tell us where we have all gone wrong.
Just imagine if everyone said NO when they were asked for help, there would be no need for this forum at all, I thought that is what is was here for so that we could help one another when possible.
Please re-think and SPILL THE BEANS and put us all out of our misery.

Thanks.

Mike

Fine. I honestly couldn't care whether you believe me or not. There is absolutely cartloads of information, (including links to), on here regarding every aspect of most systems on the Surf, btw. I merely tried to give you a hint. I have neither the time nor the inclination to wipe anyones arse for them.

Also, don't assume by the fact that you don't know something that no-one else does. Using the term 'we all' is blatantly untrue.

Find the glowplugs download in this section:

Note the graph on page 3.

Looks to me like if the engine water temp is <50c, then the plugs stay 'lit' for 120secs. What's the '2 stage' thing?

That might have been a bad example then. Only gave it a cursory glance. Unless I've completely got the Surfs system mixed up with something else, (and I'll digress if I have), the glow plug system is two stage. Primary stage, full voltage, secondary stage, reduced voltage.

Possibly... Maybe I'll stick a DVM on it and see what happens. I cant really imagine why they would bother with the complexity of reducing the voltage to the plugs.

I thought you were asking about something you already knew just to p1ss me off. Obviously not. Haven't dug out the info on the 3.0L series yet, but there's some diagrams, (not the best res, but viewable), over on toyotadiesel regarding the 2L/2LT. As far as I know, that basic system is also used on the 3.0L's too. They refer to it as superglow and afterglow, I believe.

Glow Plugs.

Well Matt I can see why you are "Old grumpy boll0cks".
I was not asking you to wipe my a**e I am big enough and old enough to do this myself.
You are talking in riddles and trying to give the impression you know more than you do and are trying to belittle and confuse people.
You say you only gave it a cursory glance I would think before you expound your theory you read the question before you answer.
By the way you still have not answered the question as how you arrive at your interpretation of the workings of the system and you also say that two voltages are used.
I can assure you that 13.4 volts DC are present on the rail on my Surf all the time the plugs are being fed and this can be up to 2 1/2 to 3 minutes depending on the temp.
Please do not answer in a rude manner, if you cannot be civil, do not answer at all.
I have never been rude to you but I suppose you perhaps feel that you must live up to your title of "Old grumpy boll0cks". but honestly you do not have to do this for my sake.

Regards.

From what I can remember from having to fix a short in the glow plug electrics there are 2 relays feeding the bar. I would assume that they both feed 12v, but the wires are of a different gauge, so I assumed they feed different amps thereby giving different heats.

How does telling you to search and find out how the circuit work class as a riddle? Btw, I am making no attempt to make it sound as if I know anything. I am working from information retained and have posted links for which I SEARCHED and found in a very short time. If it's incorrect it's incorrect. Stop whining and prove that the information I've noted regarding how the system works is false. I obviously know nothing so can prove nothing either way.

You say you only gave it a cursory glance I would think before you expound your theory you read the question before you answer.

If that made the slightest bit of sense in the context....... I quickly glanced at a diagram and incorrectly assumed it was the one I was looking for. I suppose you never make an error?

By the way you still have not answered the question as how you arrive at your interpretation of the workings of the system and you also say that two voltages are used.

I assume you were born with eyes, fingers and ears? I ain't gonna spend a large portion of time digging out any info that you can't be arsed to look for. For the last time, believe what you like. I don't give a monkeys. And it is no interpretation. I work with data seen and remembered. I do not 'interpret' anything.

Oh, btw, I'm being somewhat obnoxious towards you merely because I dislike your general demeanour. Apologies if it offends you, but the way you come across online just gets on my t1ts.

I will just mention again, as no doubt you'll have completely skimmed over what I have written above. If I'm incorrect, then find the correct information and prove so. I would rather be corrected and have the proper information than be uncorrected and have skewed information.

[Apache]

I will measure and let you all know what I find. It wont be a guess, it will be correct. As usual.

You're a gent. I'd rather be corrected if I'm wrong than give out incorrect information. As I've never paid too much attention to the glow system though, neither was there any reason to believe the existing info may be incorrect. I'll await your findings.
