Hi everyone,

I just bought my first Mercedes Benz a couple days ago, a 1985 300SD. I found it on Craigslist for what seemed to be a good deal, so I bought it with the thought of running WVO in it.

I have 2 problems right now that need sorting. First, lights. My PS headlight is out and the front and rear lights on the PS don't work. bulbs are ok so I am thinking the is some bugged wiring somewhere. Directionals aren't working either.

Second is the glow system. I found a nice trouble shoot write up from Diesel Giant and that is leading me to belive the glow plug relay is not working properly. It is getting power from the battery and on both sides of the blade fuse. With the ignition switched on, I get no voltage from any of the 5 pins that correspond to the glow plugs.

So before I drop the coin on one of the more expensive parts, I wanted to post here and make sure I'm headed in the right direction.
