Thanks people I'll head out their today and double check everything. I know the relay is in good working order

Hi no I'm not getting 12v to the glow plugs either just 12v to one side of the relay

Hi people I'm new to discovery's but very happy now I own one the only problem that's confusing me is that the glowplugs won't work so far I've replaced the relay and checked all fuses....now I'm U sure if theirs another delay im missing or what the relay has got a perminate 12v to it, but...
