Diesel RVs: 07/11/15

I came back from Down East just in time to go on a Sports Car back roads mountain tour .

As my Metropolitan Nash FHC isn't quite road worthy , I decided to take my trusty old 1984 Diesel Sports Coupe , it was a hot day and the car has air conditioning with a brandy new Japanese Sanden compressor & R134a .

As it turns out my turbo , the very same one I said I wanted to overhaul a year (or longer) ago , is really not working well so I wheezed the poor old thing up and down the Sta Monica Mountains as fast as it'd go , not very fast as I had to keep manually shifting the slushbox tranny between second and third gears , turning off the AC on the steep uphill parts , the Lotus in front of me easily ran away and I had to struggle to catch up to him on the downhill and straight sections of road .

Oddly the rest of the old MG's etc . weren't able to keep up with me , probably because of the stinking trail of partially burned Diesel fuel and oil I was trailing...... .

I was so slow , I only got the rear end to step out once and that too close to a telephone pole and ditch for my liking , good thing these are good handling cars that respond well to quick inputs , well assisted of course by Michelin radial tires and Bilstein HD gas shocks .

Anyway , after stuffing my face with good BBQ at The Rib Nest at the end of the run I motored on home and have been driving the even slower '81 240D since , I dug out the turbo kit I bought from Kent Bergsma @ Mercedesource last year and hope to attack it soon .

I have two spare turbos for parts and I bought the ' upgraded ' kit because I assume at 397,000 + miles everything that can be worn out or used up , is in this one .

BTW : the Sanden compressor seems to work well , I can only feel it cutting in when I'm going up hills , even then it barely slows me down unless I'm driving too fast with the throttle pinned .

Consider it the next time you do routine majo AC Service , I will on my '82 240D for sure and it still blows ice cold from it's Delco R4 compressor .

This photo is O.K. , do I see grey colored bare wires right where the red ones go into the bigger black plastic sheath ? .

If so that's a serious problem and yes , it needs attention as the glow plugs draw their current through those unfused wires .

Maye 1.4 MM diameter ? can't use anything less nor low cost wire that doesn't have as many strands as those old crispy looking ones do as they carry a _lot_ of current .

it's possible if not likely someone held the glow plug knob out too long or that one glow plug shorted out and so drew far too much current , overheating those wires .

I don't know how to explain how to do this as a DIY repair and it's hard to find the correct high amperage wire here in the U.S.A. maybe Bill knows ? he's a whiz at finding things .

Does the starter now turn the engine ? .

This is imperative before you address if it'll actually start .

If it doesn't turn , try jumping a nigkle between the large terminal on the starter and the smaller one ~ this should instantly make the engine turn over , if you only get a ' click ' or it groans and turns very slowly , stop and take the starter apart , clean everything well , replace the brushes and solenoid , grease the various bushings lightly , re assemble and try again ~ once you have the starter working , you're ready to move on to starting the engine .

I've been away but am back now and eager to get back to work .

So I traced the battery cables to where they connect to the car and this is what I found. How do you replace these? See attachment.
