New GPs, Blows 80A Fuse

[Jadavis]

I made a new post since I could not find this particular glow plug system issue by searching.

The glow plugs are in and I finally feel well enough to work on putting everything back together. (I took out the intake manifold since my car is a 1987 300D, 603 engine...)3

I'm at the point where I need the photos I took before I started to make sure I get everything back where it is supposed to go. My camera is taking for ever to download...so to keep moving I decided to put the new 80A fuse in, turn on my dome light, and try the plugs to see if they work. I turned the key, the light dimmed, and two seconds later the fuse blew.

Cleaned all connections
checked for continuity on all 6 wires with each wire by itself, one at a time.
installed 6 new glow plugs
Connected up all 6 glow plugs
reattached the 6 pin connector to the relay
put in new fuse then tried as above.

Where do I go now? Is my relay shot?
