TD42 glow plug timer

[Bloodyaussie]

Would anyone know why my glow plug timer takes so bloody long...?

First thing in the morning it can take more than 20 seconds for it to click and always has??

Did not think much of it until Matty pointed it out to me a few times over the weekend.

How long does yours take... Not talking about when the light goes out but when you hear the click and the system goes back to 12v.

sorry but i flick em on put my seat belt on then crank it over.. never waited any longer ... fires up pretty quickly

Mine is run via the ECU and it takes that or longer... Jaycar sell a timer kit so you can set it yourself.

Is this a direct replacement for the oem unit?

I didn't have any factory setup so I bought an OEX brand glow timer. I have it set for 6 secs with after pulses (1 sec on, 1 sec off) set to 10.
I use a Jaycar 100 amp relay to switch the power to the plugs.
It starts immediately. When it's hot, I just turn the key without waiting and the starter signal wire stops the glow process.
The after glow still works.

Mine takes about 10 seconds to click.

Mine clicks pretty much straight away once the ignition is in the on position, glow plug light goes off within approx 3 seconds

Yes same my light goes out in a about 3 seconds but more than 20 seconds for the click... Matty waited about 10 seconds and just started my car with no issues but the weather was very warm last weekend.

During the day while I am out and about it only needs 3 secs for the light to go out and never have issues.

You would have to wire it in. Its not a "plug and pray" type setup. But this is the unit that get most of the attention from ZD30 owners wanting to override the ECU's decision. Wouldn't be too hard to install I reckon, you just need to know what wires to tap into...

Is the temperature sensor working correctly for the glow plug timer?

Ohhh I am not sure... actually it is the first I have heard of it and not sure where to look?

Your vehicle is running a standard TD42 glow plug system with the control module in the drivers side kick panel? yes?.

The sensor is the two wire one mounted near the single wire gauge sensor in the engine. Make sure it's connected and the terminals are clean and tight.

I think the workshop manual has the resistance value of the sensor. I will have a look later for you when I get to my other computer.

I'll just add to this. ...... I've just noticed that I get a second click about 5 seconds after the initial click, which is about 2 seconds after the glow plug light goes off. No idea which relay it is yet coz I haven't checked.

If you have a voltage meter on the main battery you will see it drop down to about 11v then when it clicks it goes back up to 12v and its ready to start.

Here's the resistance reading for the water temp sensor. You will also need to check continuity in the wires between the water temp sensor and glow plug control module.

Shouldn't be any longer than 5-10 seconds. I ripped my timer switch out of my old 60 when it failed and replaced it with a push button......... Mainly because a replacement timer cost between $800-$1000
