Another quick newbie question: Where's the fuse for the radio located on a W114 ('72 250 sedan)? The original Becker radio was working just fine one day, dead the next. It appears it is getting no power. I've checked all the fuses I can locate under the hood, but all are intact. I thought I would ask first before I started pulling things out.

Thanks!
Dave

Re: Radio fuse location?

I have the same question, but also does anyone know where you can find a 2 amp fuse for the radio? None of the parts stores or car stereo shops have them (5 amp is the smallest I can find), and the guys at Becker didn't have any.

For fuses, check with Rusty at buymbparts.com. He has all sorts of parts you need at a price you would be dumb to not take advantage of. That said, go to FLAPS and talk to somebody who looks at least as old as your car and they will know how to find that fuse.

FUSES-- spend the $1.50 to just swap out ALL the fuses for new and you will find most problems solved. With age fuses fail and will look just fine. Do not believe them. Change the fuses and all will be better.

Re: Radio fuse location?

Fuse #1 in the underhood main box is pretty central to switched accessory power; check it and replace with a new brass fuse if in doubt. If you have most switched accessories functional, then #1 is probably OK.

There are two other small underhood fuse boxes, each having a screwed on top. One is near the coil/battery area adjacent the washer reservoir. I believe it may have the radio fuse, but I am not certain...mine is in the garage and not available to check. Also, look against the firewall on the passenger side. There is another fuse box like the other one. I believe it has fuses for the fan/AC, but I may be off, it may be the radio fuse. Like many things MB, the early wiring schematic is unclear on this so you may need to simply do a pull-and-check with the fuses to isolate accessory circuits.

As Clay suggests, the best preventative measure is to replace all the fuses with new brass conductor fuses. The original fuses are aluminum conductor and over time they corrode and cause problems.

FYI and others, Radio Shack has tons of fuses in most ratings. I go there for the little odd ball fuses in my irrigation controller.

Re: Radio fuse location?

Hi guys,
Thanks for the advice; I located the radio fuse this morning in the little fuse holder with the screw-on top, just behind the washer reservoir. At first and second glance the fuse looked ok, but eyes over 40 are not reliable. Closer inspection in good light revealed a hairline split. Put in a new one and the old Becker is working again.

Have a good one!
Dave
