HI fellas, Im chris, new here, Im a big DIY'er, I love finding innovative solutions to difficult problems, I love to fabricate things, welding, mods, etc!
Post Inspection.
Heres an update on my 81' 300SD as of today, things it needs and things i've fixed! Or if any of ya have a solution, post it! I've already Visited diesel giant tech too!

FIXED:
No dash lights or console. I made my own instrument cluster tool, pulled it out and found a burned bulb after checkin fuses and such. Still didnt work, so i played with the dimmer rheostat and got a flicker. Well since even at max setting the lights arnt that bright to me and a new dimmer isnt cheap, i wire brushed the copper contact bars on the back and took a piece of wireing, stripped it, twisted it, and made a bridge with it by sticking it in the holes and soldered it in place! Works perfect!
Odometer didnt work, stopped at 299K miles! Well beeing im a BMW tech and this is a problem on older bimmers, i removed the speedo unit and just like a bimmer, the normal broken part is the tiny rubber main gear that powers it had split off the brass center. After removing the gear cover and the other gears, i warmed the brass piece with a micro torch and using side cutters, gripped the gear shaft just below it and used another pair to lever the brass chunk off! the new bimmer gear pressed right on tightly as it should and reassembled it. Works perfectly! BMW and M-B both used VDO gauge and the gears are the same!
Cleaned ALDA banjo bolt and line. And adjusted ALDA some. All is well here!
