Wire short somewhere ????





Put your finger on the voltage regulator and the horn relay to see which one is buzzing. voltage regulator bad, horn relay good, if the key is in the ignition and turned off
the alternator has power on the ground Side? is that with the motor running or all the time. If its all the time you may want to replace the voltage regulator, they're cheap and you can just eliminate the headache of trying to troubleshoot it. if its with the motor running it could be the alternator and/ or the voltage regulator. You should pull the alternator and have it tested. Who ever repaired it could have shorted it. Its a free test at most parts stores.
the courtesy switch can be accessed through the wheel well right behind it. There's a little 3x5 size door there.
check your wires, i saw some with the insulation missing and you could have shorts everywhere by the looks of it. Those all need to be covered with tape or liquid tape. I would start saving for a lectri limited harness. You can buy them in sections so your not wiring the whole car https://www.lectriclimited.com/engine-harness-103691

I agree!
I think I'd at least buy an engine harness at this point.
While still a lot of $$ it's the least expensive of the 4 main harnesses and probably the most straight forward to install because the access to it is so good.
One thing to remember though is that the harness will be configured for all the original components, so things that have been changed over the years to parts that are different in some way than what were on the car when it left St.Louis MAY cause some connection problems.
What I see in your photos would make me quite nervous!

Alan

i would disconnect the alternator and see if your battery dies. It should not have positive power on the negative terminal.
you need to climb under the and see iff the tach has the ground wire connected to it. Its black and might have a slid on terminal. That or its an eye and just gets screwed on. Look at the speedo to see.
This may be the signal light problem.

Tach light- there's a ground wire (black female spade) for the Tach AND the Speedo-if the bulb is good and the Speedo light works- that's more than likely your problem...
Here's the location-
You really need a VOM meter NOT a test light- Can get a decent one for under $50.
You need to check current draw- not whether or not you are seeing voltage.
Think of electricity as water- the voltage as the height of the water ( can just think of 12 feet high = 12 volts) and current or Amperage as how fast the water is flowing. If you battery is full of water and 12 feet high- with no leaks your there ...but you have a leak somewhere not a short-However-you need to determine how fast the water is moving by measuring the how many amps(or part of one) are being drained out-
Here's how-
You'll put the meter in a series between the negative battery terminal and the neg cable.
Here's a good video-
Just want keep you from burning the car down. The big gauge red wire running around the brake master cylinder- unprotected- could EASILY get caught in the hood latch and looks like the orange might be first- that's a dead short and can easily start a fire...
This make me more nervouser!!!

Unfortunately that won't tell you what you need to know.

I will say- that replacing the harness (under the hood)- maybe finding a local member to help you out- There are a lot of helpful member here- most will work for food (and beer!!!)

the plate must be on the back
Member... redrdstr72 ...developed a method do the repair to the switch's mounting plate without taking apart the whole car.
You might want to search his posts for the information.
I'm thinking it may be from 5+ ago.
