Glow Plug Warning Light

[ajstars]

Hi,

My 3rd generation Surf has never displayed a glow plug warning light - which I assumed was due to the bulb being blown, but I have now checked the bulb which is all working and fitted a volt meter which shows no Battery drain decrease a short while after the ignition is turned on which would make me think the plugs are not heating.

Any ideas what could be cauing this problem? My thoughts were heater plug relay??

Suggestions welcome,

Thanks

The relay or the glow plugs, they used to be wired in series so one off all off.

Bang a new set in anyway they`re not very expensive.
