Fuses for '73 280SE 4.5

I know it seems that there are a lot of post's about fuses, but I can't find one to answer my question. The fuse door is missing on my car and the manual doesn't say which fuse is which. Could someone at least refer me to the correct amperage and maybe even what devices each circuit runs.

Having just gone through this on our '72 350SL, I can suggest:

- First have a look at the cardboard strips behind the fuses that are numbered. On my car the fuse amperage is printed next to the fuse number along with a circuit number. The area behind the fuse is color coded - White means 8amps, red is 16amps and blue is 25amps.

- If you cab find a wiring diagram, the fusebox layout is in the middle and you can trace which fuse is connected to what.

- Chilton's Mercedes Benzes 1968-73 has the fuse layout for the 280SE 4.5 (and the wiring diagram) under Chassis Electrical.

This is the short version of what they say:

1. 8amps courtesy, parking, clock, flasher, etc
2. 25amps wipers, cig lighter
3. 8amps transmission controls
4. 8amps fuel pump relay
5. 8amps turn signals, brake lightes fuel gauge etc
6. 25amps auto choke, heater blower
7. 8amps lights
8. 8amps lights
9. 8amps hi-beam R
10. 8amps hibeam L
11. 8amps low beam R
12. 8amps low beam L
* 25amps Electric sunroof
* 16amps Rear defroster
* 25(4) electric windows

Good Luck.

On my car, nothing I found matched the actual car, but some were close!

Thanks for the great response. The fuses are numbered, but no amperage or colors... Your list is perfect. I mostly know which one is which but now I should be able to narrow it down exactly for each system. I have a few electrical glitches and need to figure if they are related or separate.

One question, does the manual say anything more about fuse #7, specifically dash lighting.

thanks again,
Chris

Chiltons for Fuse 7 (8 amps) says: Right Tail light, right parking light, right license plate light, instrument lights.

I tried to follow the lines on the reduced size wiring diagram in Chiltons, but I go crosseyed!

That's great. That confirms my thoughts and isolates my problems. Somethings shorting on that circuit for Fuse 7. Now just to follow the wires.

Thanks

Found a melted wire from the right tail light to the right license plate light. Simply unplugged it from the tail light and the rest of the system works great. Looks like the ground came loose and shorted out. I'm only disappointed that the dash lights didn't come on. Looks like I'll still have to pull it. Just picked up a Chilton on eBay.
