Try a PM to this guy, engr693. He's got a '72 parts car listed on his sig.

 

There are good pictures of a fuse diagram on a thread dated on 10-08-07 (need fuse diagram 76 450sl).

 

Sent a pm back:

I will look on my fuse panel when I get home and will take a picture if mine is there and email it to you.

Regarding my console, I sold it to a guy in Canada last year.

I will look for the electrical part on my car and see if I took it off the parts car. The chassis is gone but I have a pile of parts on the shelf in my garage.

I do have a body and chassis manual, engine manual, and the MB classic CD. Perhaps if the diagram is not on my fuse panel cover, I can locate it in one of those places. I will get back to you.

If nothing else a picture of the fuses and their locations in my fuse panel may do.

 

I'd wait and see what Gary comes up with. It seems a lot of things changed in those first few years.

 

1973 450SL Fuse Panel

If I could read German I could tell you what this says.

As best I can translate:

1. Automatic Antenna
2. Parking, Boot (Trunk)Light, Glove box light , Entrance lights, Warning Flasher
3. Radio
4. Flasher
5. Windshield Wiper, Discs washing pump (whatever that is), Signal horns, cigarette lighter (I think)
7. Heat-Chill Blower
8. Instrument panel (I think)
9. Additional fan - Air Conditioning
10. Can't read this one on the cover
11. Rear window heater
12. Automatic Gear ?? (Something to do with Transmission?)
13. Sidelight right, Tail light right,
14. Main Relay, Fuel Pump Relay
15. Nebulous Light, Nebulous Tail Light
16. Sidelight Links tail light left
17. Right high beams
18. Left High Beams
19. Dimmed Headlights Right
20. Dimmed Headlights Left

 

I got some translations and have edited my previous post

 

Chiltons says stoplight and automatic choke for 10. For 6,, it says sidemarkers. Where you have sidemarkers, it says clearance lights.

I will check my car out tomorrow by pulling fuses. The main thing, is now knowing what the fuse ratings should be, I can put in the proper fuse.

 

Gary (engr693),
Thank you for your post w/ translation. It helped me track down my electrical problem quickly and easily. My '71 is back on the road... with lights this time!

Here is the card for the 73 which I understand is identical to the 72.

I know this is old but any thought on why when i put a new fuse in 2 it blows up the second it touches?

 

You need to fill in your user CP data so that we know just which model you own.

 

Difficult to state 100% because I don't have your model or year. On the '73 fuse #2 protects clock, warning flashers, trunk, glove box, courtesy and parking lights.

 

You must have a short to ground somewhere. The fuse layout varies a lot between models. There should be a diagram inside the fusebox cover that shows which circuits fuse 2 serves for your 74 slc.

I am away from home, but someone with a hard copy of the chassis manual may be able to find the wiring diagram for your '74 SLC. It too shows fuse allocation, but the one in the car is more likely to be correct.

 

74 ETM

1974 ETM indicates that fuse 2 is powered by P30 (battery bus) and protects the following:

1. Trunk light - easy to isolate via connector plug at light fixture
2. Entrance lights - these are in the knee bolsters; again easy to drop and pull plugs at fixtures to isolate
3. Dome light - I think only for an SLC unless the '74 has a light in the windshield header like later models do

***Items 2/3 are switched in series by door switches that should be tested if it is found that the interior lights are causing the problem

4. Power Antenna - plug on left side inside trunk
5. Clock in tachometer - most difficult to isolate (do this one last)
6. Glovebox hand torch - if stll present and plugged in, pull glovebox liner and drop fixture by pulling positioning clip, disconnect plug to isolate

 

Nr. 10 is Bremslicht....Brake.
Probably too late, but you never know.
