DK45s Really rough when starting

[seacap04]

I had the same problem a while back. Ended up being a bad electrical connection at glow plug buss bar. I posted pics of my repair but I can't seem to copy thread post here. Do a search for "DK45 glow plugs" scroll way down until you see Dk45 glow plugs posted by seacap04. Hope this helps.
