[diesel_mercedes] Did they upgrade the fuse system in the w124's

 

I see a few grounds through out this car with some mild corrosion like you see when a battery drains and does its thing as it to metal.

I'm tending to think there is a ground gone awry.

I bought the car to yank the engine and transplant into a truck so I could have a diesel small truck, specifically a nissan hardbody that I already have that is needing an engine refresh.
Among the factors of using the motor for a transplant is the ability like you say to have a electronic dependent free car.

But, the car was so nice with no rust, dents etc that I began putting things back in order.
I think I'm running out of patience with this one though.
It may be transplant time.
I could handle a window or a antenna but not the turn signals that could get someone killed.
I always hated the little fuses like in the w123's when I had to deal with them in the vw beetles, not just the fuse but I found the system flaky.

Except for the aluminum head it sounds like a no brainer to get the w124
I am curious did they convert the fuse system in the 124's to the present style fuses like we have in american cars?

Re: [diesel_mercedes] Re: Window Switch Service

 

I don't know where you downloaded them from, but the cd that covers the 126 cars breaks out the electrical systems into  groups by function.  There are obvious differences between the 123 and 126 cars, but the 126 wiring set ups are  a good starting point.

I didn't think haynes would have this car in their series.

The 300SD should be identical and looking in the prefix of this manual it states thru 1984 so I think this manual will cover the 300D

W116 library : Mercedes-Benz S-Class - 280S, 280SE, 280SEL, 300SD, 350SE, 350SEL, 450SE, 450SEL & 450SEL 6.9

I believe the flasher relay on the W123s is located in the center console. It may be part of the hazard switch.

Bad turn signals do not cause the windows to not operate, or visey-versey.  The electrical systems on these cars, if anything, are much MORE robust than most any other cars.  Not a computer or even integrated circuit to be found anywhere to keep the car from being drivable (just in the radio, maybe the glow-plug relay, AC/heater controls and cruise control).  Individual components (alternator, switches, etc.) are rebuildable, and the whole system is EMP-proof, so, should the Iranians or Uncle Vlad detonate their nuclear device over the country to knock out the grid, rendering every other car on the road useless, you'll still be able to start up and drive.  The engine doesn't need electricity to run, only to start.  (Even then, the pre-'81's, at least, are push-startable!)

Sounds like you don't have the Haynes manual for your car.  They're still available:

http://www.haynes.com/products/productID/277

You can find them on ebay for less than list price ($26.95).  They may also turn up on craigslist if you live in an area where MB diesels were popular both when new and now (like SoCal).  They're a must-have if you want to keep working on the car yourself, and yes, they DO have schematics in the very back....

Is the flasher unit directly behind the cluster? and is it identical to the two items on the driver fender well right in front of the fuse box and covered by a little black snap off cover?

If it is then yes I picked out the turn signal lever and that little silver box that I just discribed. and tried them both in my car but it didn't help so I replaced with my parts.

I havn't messed with the passenger rear window or the antenne.
Is the electrical system so fragal that a non working passenger rear window switch could brake the circut for blinkers, hazard etc?

Sure could use a wiring diagram of the car.

Where is the flasher unit located and is it square or oblong?

Re: [diesel_mercedes] Re: Turbo Binding Up

 

Rebuilding your turbo really helps the car function.
It'll seem like a new car, when the turbo engages throughout the RPM range.
$100 kit, or somewhere around $250 to have it done (off the car)

Fragile isn’t the best word; more like peculiar. The electrical things are connected in such a way that if one circuit stops working, another won’t work.

I have a 1961 Mercedes. I seem to remember (30 years ago) that when my low fuel light comes on, the rear brake lights stop working. Bill in Oregon
