glow plug problems after $1000 spent

[kiwijase]

i checked the water temp sender with the engine bone cold and it read 4.2 on the meter.
I also compared the glowcontrol unit to a pic and mine has no 4 pin in the same place as the pic(which i assume is earth,but mine is empty)).The pic shows a plug with 10 pins,my plug has 14,but not all have wires running thru them.
Thats pretty much where i stalled testing things before jumping on here and asking for help,the plug has me stumped!

ill check the relay in the morning,its gettin dark over here now.
Thanks for all your help today Rodney,ill report in tomorrow on the relay test.

Have you had water inside the vehicle? up over the pedals?

What difference would this make?

[kiwijase]

thats where the glow control unit is,around that sort of height,so is the ECU on the passengers side from memory,i may be wrong though.....id suppose water could bugger either at theat level of water?
Ive never had water anywhere near the inside of the wagon anyways.

ok,with the relays,im not too sure which one to test,and i dont know what voltage im looking for.
How hard would the button option be Rodney,im losing patience with the bloody thing altogether.
Thanks again for your help

Reasonably straight forward, we will just use the push button switch to work one of the original relays.

What colour wire connects to the glow plug busbar? one of the relays should have this same coloured wire, this is the relay we will use.

What are the other wire colours at this relay and wire size?

[kiwijase]

in one relay there is a large white with red trace (loops between both relays) ,a large red wire,a small green and black,and a black with brown marks on it.
Both relays have the large white with red trace,and thats the wire that rins to the glow bar

[Yendor]

Which relay does the large White wire go to? (from post 18)

What voltage does the large Red wire have with ignition off and when the glows plugs are on?

Can you take a photo of the wires at the relays?

[kiwijase]

the large white wire comes from what looks like a solinoid,into the first relay
Heres a pic Rodney.
