Re: [MBZ] Mystery headlight
Yeah. Bad wire leading to the fuse box from someplace else and there was damage to the harness out to the light too. I will have to source a bunch of new wires for the car in future, but was able to bypass the breaks for now. Found the water pump is leaking now. I am begining to think that I need to strip the car down and rebuild it. That should at least deal with age related items. Not going to happen, but I can still think. clay 1974 450sl - Frosch - Two tone green 1972 220D - Gump - She is green, simple and ran 1995 E300D - Cleo - Used by the Queen of Denial POS 1987 SDL - Beware Nigerian Scammers On Mar 2, 2013, at 5:02 AM, Mitch Haley wrote: > clay wrote: >> Electrons flow.

Re: [MBZ] Mystery headlight
Look for a corroded connector somewhere between the fuse box and the headlight plug. I eventually ran another wire on my old 300D, I never did find out where the problem was. It's also possible for the wire to break inside the insulation.

Re: [MBZ] Mystery headlight
Still no low beam on driver side lamp. Right side lamp does function. Tested at the headlamp by inserting the probes into sockets. Negative lead to ground wire. I took off the socket cover to make sure I got the right wire. Inserted the positive probe to the white lead and the yellow lead wires separately. At the fuse box, I removed the 20amp fuse from the socket and then put the probes to the contacts.

Re: [MBZ] Mystery headlight
Headlight for low beam is only getting 10.98volts Headlamp for high beam is getting 11.16 volts So does this mean it's working again? That voltage drop (is this engine-off?) sounds plausible for R107. See: http://userweb.windwireless.net/~jimc/JSLlights.html Relays will cure a lot of this drop, making brighter headlights. Our 450SL had 400W of high beams when we sold it. Take that, deer! Fuse box shows 11.52 volts flowing from one end of the fuse holder to the other. Your terminology confuses me. Volts don't flow, amps do. Does this mean that you measured 11.52 volts (to ground, lights on) at both ends of a fuse? Which fuse? I would expect some slight drop across the fuse if current was flowing. The simplest and most direct measurement is to leave the engine off and turn on the lights, then put the positive meter probe on the center post of the battery + terminal (not the clamp, the _post_), and the negative meter probe on the lamp's non-ground contact. Measure the voltage drop directly. It's surprising how much it is, and ought to be around a volt. You can do the same between the battery negative post and the other filament lead on the lamp. Usually the ground side has much less voltage drop. Add the two readings, then measure the battery voltage directly (lights still on) and figure the percentage voltage loss of what the battery had available. You'll be surprised, I know I was.

Re: [MBZ] Mystery headlight
Check the wire, they do break. Also check to make sure it's still screwed to the bottom of the fuse holder, the screws have been known to come loose. Also make absolutely positive that you have a good fuse, they are separate in the R107, one for each beam of each headlight. Bad contact at the fuse holder will cause trouble, too. BTDT, had the same problem on my '75 Audi Fox, had to work on getting the corrosion off the fuse holder so it wouldn't burn out the fuse all the time, too much current in the ring around where the fuse contacts the holder from intermittent contact.

Re: [MBZ] Mystery headlight

Re: [MBZ] Mystery headlight
Do you have a lamp out indicator on that car? If you do , the current for the headlamps goes through that "relay" (not a relay, but is in the same box as the rest of them). If that lamp out module is bad, you can have no headlight. I never did figure out what the problem was on the old 300D, I finally just ran a new wire from the fuse to the lamp. Worked fine, but the lamp out warning came on all the time. You can also have a loose connection on the bottom of the fuse holder inside underneath. Not visible until you take the fuse box apart.
