Bongo Fury

Hi Can anyone help me find which fuse is for the glow plug relay. I had to replace that recently and then bongo started no bother at all. I did about 8 local journey's and then it stopped again. I think it might be a fuse that is causing the problem so i would like to change that before I have to buy another relay, also has anyone had that problem before and can hint what actually causes it in the first place.
thank you Eileen (madmacks)

Its here, top left corner, hover the mouse over the green fuse "1.25 sq Glow" for a picture of it;

Perhaps you have a short on one of the glow plugs?
