Ok so here is the scenario. I'm trying to help a buddy of mine figure out why his glow plug isn't working right( its not goiing off basically). the fuse is good and i was trying to trace the wire out to the relay and get the fuse box off. while trying to remove the box i noticed i big block fuse on there in the way. So I took the fuse out and when i was going to put it back in i noticed that it was put in from the MANF backwards or up side down dependin on how you look at it. any way he has never removed the fuse or anything and i don't really see it being the problem with his glow plug but it just seemed weird to me and i searched the internet for what and EDU was and all i got was its a Engine Dispatchable Unit what ever the he;; that is. any info on this would be great.

Thanks
