KZN185 How to adjust the glow plug timer?

To Apache

I look forward to your findings as you also have a 3Ltr engine the same as mine.
I hope mine is not screwed up but I think it seems to work just fine, the only trouble I had was to find out how the damned thing worked in the first place as it is confusing with the light going out with power still on the rail.
I even changed the plugs thinking they were duff.
My last motor which was a Landcruiser started with one turn of the engine with zero waiting time summer and winter and that spoiled me for everything else.
Regards.

I am sorry for you and your attitude I am glad I do not live with your outlook.
Thank goodness nearly all the other contributors to this fantastic form are interesting and have a normal grip of life.
Your last post says it all

The End.

Stop trying to insult me when you think I'm no longer online. That is the demeanour I'm referring to. Have I cast aspersions on any part of your life? No. Abrupt I may be. Fortunately however, I am not ignorant like some.

[Apache]

When you two have finished casting aspersions, could you pick them up? They are making the place look untidy.

right.

i went out side this morning and did thus.

13.7V at the glo plug bar. heater relay clicked (i presume off).

i turned it over and had.........13.7 volts ??, for a further 110 seconds.
i couldnt hear if the starter relay clicked again, but there was an ubrupt cessation of voltage at 110 seconds after starting, so about 116 seconds in total.
i got home and it was nicely warmed, so i let the engine idle for about 30 seconds, to run it down. i started it again, and the starter relay clicked off really fast, about 1 second. it had no voltage to the bar, when running.

mine is a far superior 2.4, and quite old so does this make any sense in this debate.

[Apache]

Thats what I thought would happen judging by the diagram / graph, though we wont be sure thats what happens on the 3.0 (though i cant see why it would be different) until I test it.

However, 13.7v out of a 12v battery with the engine off is unusual unless the engine has just been run, as is 13.7 out of a system with the engine running.

Battery would normally measure 12v when its been sitting for a while, and 14.4 under charge. When was your meter last calibrated?

[MattF]

It does indeed Graham, cheers. T'would appear that it is indeed a straight forward temperature/duration setup.

I cant help but titter when I read post 10.

It's OK mate, we all make mistakes... well... not all of us.

I'll take a stab at the answer to that being never. There's very few who buy a calibrated, or keep them calibrated, meter, unless they have to.

Must admit though that this has piqued my curiosity now.

I don't mind making the mistake a first time. Making it a second time would be annoying though. There does seem to be quite a bit of disinformation regarding this system, it would appear. Hopefully, we should have a proper rundown soon?

Example. The third thread on this site when you enter 'super glow' into the search box:

Interesting, and partially wrong too by the look of it.

Perhaps later surfs do something like that? It makes sense to overdrive a plug for a short time to get it hot quickly (like you can overdrive an LED if your are flashing it with very short pulses), then maintain the heat with a lower voltage. However, I would imagine the plugs will be of a different spec to the ones fitted in the cars we're talking about which it appears get full rail vots for two minutes or not at all, determined by the water temp.

I cant honestly see much benefit in the two stage system other than a very slight reduction in start time.

[MattF]

Running them below their rated voltage would be beneficial for longevity, and as you mention, the initial peak would lessen the heating time. I can see this becoming one of those subjects. There appears to be a lot of conflicting information.

T1 is the light lighting time, T2 the afterglow time.

Straight from the KZN185 book, no argments, the facts!

Fools.
