Hey guys, just joined. I Heard about this board from another member. I am having a problem with my inlaw's 86 300 SDL. When you turn the ignition on the light for the glowplugs does not illuminate and obviously the glow plugs do no turn on. I know(from reading prior posts on this forum) there is a relay with a fuse in it. I suspect one of these to be the culprit but as I do not have a shop manual for this car I do not know where to find it. Could anybody give me a hint of where to look? If I find the fuse or relay to be bad are they something I can find at a local part store? Any help would be appreciated. Thanks
