Thanks I'll have to look into this then

Ok that sounds good, now is there any way to check that the glow screen system is working before I look at diconecting it, or rout around it? Also is there a way to change the screens or do they never wearout?
The glow screen stays on longer when its cold and shorter periods when warmed up. It it does those things you could consider it operable.
Glowsceeens wear out and are replaced

Thanks, is changing the screens a job that I can do at home or is this a job for a specialty shop?
Although Iv never done a screen before I don't imagine it would be a hard fix. I was going to post pics of my glow screen override install however I think i managed to delete the pics before i uploaded them to the comp 
s***ty.... but its a real simple fix, if you pick the truck up and need a hand with it, im down in Victoria your welcome to stop by have a beer or two and we can get it sorted out in less than an hour.

Its a regular on the job install,like nearly everything on these except the inj pump. Landcruisers were designed to have nearly all the maintenance done in the field if need be.
I think the glow screen last a few years at least.

Ok now here comes the dumb question...................
So the 13bt uses a screen to preheat the air before it goes into the head, is that what I'm seeing in the picture?
Now if the glow screen is preheating the air charge then due to the turbo doing kinda the same thing once it is running, then the glow screen would not have to work for all that long right. So am I off in left field or am I barking up the right tree?
I have been around Diesels but I thought that they all had a glow plug type system in the head much like a spark plug.
As for the diesels that I work on right now will a Turbine in a little different than a piston pownder, though to start they use an igniter and once the flame is going and the engine is at self sustaining then the igniter is off.

Real simple just unplug the temperature sensor plug [the one with two wires] at the thermostat housing. Then you have complete control over the glow screen with the key switch for testing. Turn the key to the on position, and if the glowscreen is working you will see a noticeable drop in the system voltage shown on the panel meter.

Ok that sound simple enough, bonsai has it still they are sorting out a couple of issues with it. I'm just trying to get an understanding of the system, thank you for your help.
One more question is there a place that has shop manuals for cruisers or am I stuck with the Haynes ones?

Yes
Before they had either ,they lit little fires inside the manifold. I dont why they use 2 different systems but I think glowplugs are more common
Is that mess a question or a statement?

I have another question for everyone here how much did the BJ7x series cost when new in the 80's. Just wondering if these vehicals have gone up, down or are around the same price as when new.
Yes the 13BT is screen not a plug; my understanding is the screens are a more robust system and are easier to field service than a plug (IE why you see them in the 13BT and in some of the older utilitarian BJ40s.
Both plugs and screens are only used on startup, and even then often only in cold conditions. The basic idea is to ensure that the fuel being injected into the compressed cylinders will fire, when everything is super cold IE first start in the morning at -10, its unlikely that the fuel will combust. Its during this time that you would want to "glow" the engine for a few seconds before turning it over, after it's fired and there is combustion occurring the latent heat produced will be more than enough to maintain the engine so the glow system is un necessary. However this has nothing to do with the turbo, there is more than enough heat to maintain the engine from all those little explosions.
On my 89 BJ74 which is curentally residing in Victoria I haven't HAD to glow it at all this winter, that being said when things approach the minus territory it can make starting easier to glow on a cold start.
Think of the glow system like you would ignitors on a turbine, only used for starting, after she has spun up combustion is self sustaining.
BTW, which airport do you work out of? fling-wing or fixed?

Hey Walker - Thanks for the explaintion, it's all starting to make sents.
As for work I'm working out of Port McNeill on fling-wings, how about you are you working in aviation?

In Australia they were in the $33-$35k price range but the aussie dollar was 50c to the USD.
They were not sold in Canada new except the BJ70. There are car value books on the net which give you that info

Thanks rosco.
a turbine in your helicopter is a continually burning combustion chamber. The diesel is compression ignition. It's the compression that ignites the fuel. The glow plug doesn't ignite the fuel on a diesel. In a heli turbine it ignites the fuel.
On a diesel the glowplug warms the head enough to have the fuel start to ignite on start up. Once it is running the head warms up and the detonation becomes easier. The glows only glow prior to start up. And sometimes after for a short bit till the head is warm.
The glow screen uses warm air to help the compression ignite the fuel. Once the starter is off the glow screen quites.
Glow screens are generally on diesels that are called direct injection. Do a search to find out about them.
If you need a clarification on the turbine just PM me.

Hi brownbear thank you I was thinking of a diesel glow plug like a spark plug on a gas engine. I didn't fully understand what the glow plug did, I knew that the diesel used compression to ignite the fuel air with heat.
I do understand the turbines, it was not the best example to use. When I did I was thinking of the igniter cycle only being on with the starter, much like the glow plug.
Sorry for any confution

The glowscreen is on full power before starting, once started the glowscreen stays on for about a minute at low power. If one watches the volt meter one can see this clearly.
