Hi 'ya folks,

This weekend I replaced the glow plugs on my OM602. While I had the plugs out, I ran a reamer through the glow plug cavitys.

Anyway before I installed the new plugs, I cranked the engine over to blow out any carbon that may have dropped into the cylinder.

Now that the car is back together, I do not get 12V at the glow plugs, however the glow plug light on the dash continues to work as expected.

When I had the plugs out and cranked the engine over to blow out the carbon, I guess it is possible one or more of the glow plug wires may have come in contact with the engine block.

I found a schematic of the glow plug circuit on the net but there doesn't seem to be a fuse on the high current feed.

Is there a fuse in the glow plug circuit?
