76 300D no power to preglow system, #4 fuse blows

I don't know if this new problem I've found has a direct link to the ongoing problems of the car not starting under any circumstances, but this morning I noticed that everytime I turn the key to position 2, fuse #4 (8 amp) in my main fuse box blows. It supposedly is linked to horn, emission control, carburetor heater (n/a), delay switch, and turn signal lamp. Also, when I hit the hazard lights, fuse # 1 blows. It goes to the warning buzzer, auto. antenna, trunk lamp, reading lamp, clock, rooflamp, hazard warning lights(l/r)and the fuel supply shut off valve.

240D spun rod bearing and can't find parts!

I'm trying to find undersize rod bearings for a 1976 240D I just picked up. Seems to be pretty easy to find standards but that's it. Is it possible to return a crank journal to the standard size if the bearings aren't available? The engine was totally rebuilt a few years ago but... kid driving, hole punched in oil pan, ran out of oil and that's it.

115 front seat belt issue.

Hi all I'm in a bit of a fix with the local car authorities. I currently have 2-point seatbelts in my W115 (one near the shoulder, the other in the middle of the bench seat). They are saying that I can fix a 3-point seat belt in my W115 and consequently refused to let me renew my license until I change it. My mechanic though is saying there is no where to bolt the third point (somewhere under the shoulder). Can anyone confirm which of the two is right? Mark

SPEEDOMETER/ODOMETER FAILURE ON 76 300D

THE ODOMETER AND SPEEDOMETER RECENTLY QUIT WORKING ON MY BENZ. RIGHT BEFORE IT COMPLETELY QUIT, I NOTICED THE NEEDLE FOR THE SPEEDOMETER BOUNCED AROUND ALot, then...nothing. some of the lights, such as glow plug, brake sensor and battery lights still work, but the regular illuminary dash lights do not. I replaced the bulbs, but still no light. Also the old becker radio did not work and i pulled it out, but can't seem to figure out what config. to hook up a cd player. could the radio issue be related to the failures on the instrument cluster?

starting problem

I have a 76 300D that I am having a strange problem with. Usually the car will start without any problem two or three times, and then it will appear that the battery is too weak to even make the car turn over, although the headlights and other electronics still seem to be at full power. I have had the alternater tested and it seems to be working fine. I took the battery back to Wal-Mart and their machine (as well as AutoZones) found the battery to be good.

1975 230 parts help

I bought a decent, very original 230 sedan a couple weeks ago. Overall the car is in pretty good cosmetic condition but the engine needs help. The compression is below the minimum at around 100 to 115 pounds. It does run but it's pretty weak. I've searched online but haven't been able to locate a source for parts to rebuild the lower half. Pistons, rings, bearings seem to be a rare commodity for this engine. Is there a source I've missed or are the parts just difficult to come by?
