Hi
I have removed my dashboard in a 450 Sel 1979. There's a lose connection coming from the harness to the key switch. A White connection with 2 wires, 1 red and 1 red with a green thin line.
Anyone know about this? Hard to find in the wire diagram.

How did this conversion go?

Nevermind. I fixed it by replacing the little light inside.

Cheers guys.

Quote from: UTn_boy on 16 March 2024, 06:48 PMI just can't wrap my head around how something shorted, as the only way this could happen is if the radios ground wire made contact with a 12+ source, but the ground wire on these radios unscrews from the rear before removal.  Minus the large gray cable that goes to the separately mounted amplifier, there are only three connections on the actual head in unit (the radio).  A ground, a 12+ bullet connector, and the coaxial lead for the antenna. 

Regardless, the Mexico and Grand Prix models have a fuse on the inside of the radio.  You have to remove the top of the radio, and you'll see a printed circuit board, usually on the top left, that will hinge up/open.  On the underside of this circuit board is a glass fuse that is filled with white sand and probably/maybe a green and blue stripe around the glass part.  I forget the amperage rating, but it'll be printed on the metal end caps.  Do replace it with the correct amp fuse so if you short something out again the fuse will blow before something more important in the radio. 
I replaced the fuse, but the radio still doesn't work.

Does the wire that isn't connected to anything have something to do with it??

The multimeter says that power is going to the amplifier through the radio. So I think something is working...?

Quote from: UTn_boy on 16 March 2024, 06:34 PMThe bulbs that light up the climate control are Mercedes part number 072601-012230.  They're a T5 type bulb with a 1.2 watt rating. 

The bezel behind the headlight switch doesn't light up on a W116.  Only the orange or green dot in the center of the headlight switch knob lights up when the rear fog lamp is on (by pulling the knob out, or rearward, two clicks).  This bulb is also a T5 type bulb, but is rated at 0.4 watts.  If you use a 1.2 watt it'll melt the plastic knob when on for long periods of time.  This bulb is Mercedes part number 000000-001061.  Bear in mind that a lot of places will list it as a 0.5 watt bulb, which is fine to use, as well.  It just became easier to say "half a watt" rather than "four tenths of a watt, etc. 
tha perfect. Thanks

How is the power of the 3 liter straight six?  I always thought that the body of the 126 needs that 560 torque to get up and go.

Quote from: Jed on 16 March 2024, 03:02 PMMy recollection is that the radio fuse on the w116 is the long inline style fuse located in the bottom of the fuse box in the engine compartment. Not the push in ceramic style fuses but the ones you have to unscrew to get the fuse out. Did you check those? There are typically two in there and I can't remember what the other one is for?

I tried the inline fuse- it's the one that you push and twist right? That one is clear.

Is there any other fuse that could blow?
