If that works then

I assume there is a problem between the battery and the plugs in the ECU?

    I checked the voltage through the plugs and the resistance. All the plugs were ok. I assumed the plugs would earth through the multimeter or I would not get a reading.

    The glow plugs must be earthed to complete the circuit, thats why they did not get hot - normally they are earthed through the head

    With them not being earthed, its like they were not connected, if you can understand that

    The multimeter does not earth the glow plugs - it can be considered seperate, only for measurement

    from the information you have given - sounds like the glow plugs are ok, and the 10.5v is just the voltage drop

    Have you got jump leads? They can be useful for testing glow plugs off the car..

    Oh well the plugs are not the problem. Connected the jump lead to earth and a good glow after 4 seconds so I guess i will have to look at the fueling. Time to get the injectors tested.

    Thanks for all the help
