Fuse/Relay Diagram
 

Hi Again..Does anyone know where I might be able to find a Fuse/Relay Diagram for my 1981 380 SEL?? Thanks!!

There is no such thing as fuse relay. Maybe you are referring to a certain electrical component with a relay contact connected to it. If so then the relay diagram is drawn in the relay housing.

What I was referring to was the fuse box which also has relay switches in it. All I need is a diagram of the box for a 1981 380 sel which is not printed on the inside of my fuse box. Thanks for you info though!

Sory cannot help you with the diagram. But I have some hints that will help you analyze the problem.
Each relay in the fuse box controls a set of load or equipment in your car. You can refer that in the fuse box block diagram. Each relay terminal is marked with number (say 85, 86, 87 ect.) if you refer this on the relay schematic diagram.If you suspect a load connected to a relay not functioning when you flip the sw., check the relay for that load (equipment). Remove the existing relay and replace with a good one. You don't need to buy a relay right away. Try it first with the other relay installed with the other load that is working normally. Make sure it is the same size of ralay you are replacing.
Some relays are connected to a fuse in the fuse box. But most relays are not because it carries only a fraction of current when energized. The one that controls the relay is the one that carries high surge of current when it is turn on at an instant, that is why a relay is used. For this, a fuse is provided to that load usually in the range of 20A and above. Relay load is isolated from the load it is controlling, say for example the radiator fan. A relay will still be on (contacts closed) even though the fan is inoperative, in this case the fans fuse is already blown out.
Always use a multimeter when checking for power and continuity.

Thanks sooo much!! your info was extremely helpful!!!!!

It's on the CD Rom, about a 9 meg PDF file. If you need it immediately, email me tonight at greenacres2@attbi.com with a fax number and I'll print the page to fax to you from work tomorrow. It doesn't take long for the CD set to pay for itself if you're going to make even just a few repairs. Available through FastLane or PartsShop on this site.

Thanks for the info..what is the name of the cd rom?? and I could really use it now, but I don't have a fax. Thanks for offering to send it though!!

Click the "PartsShop" button on the top of this site, scroll down about half-way, you'll see a list of shop or service manual cd's currently in stock, you want the W126 version. Or call Phil at 1-888-333-4642. Great thing to have.

Thanks!!!!!!!!!
