Hi. Still on my 84 Corvette with losing voltage while sitting. I am trying everything in stages. Now I have unplugged a connector in the passenger footwell. Again, with the Ctsy/clk fuse and when taken out I get no voltage loss. Fuse in it will drain the battery over night. Just to make sure I did get the battery checked and it is still good. With the battery charged, the car starts right up. Photos. This is right at the interior, passenger side, where one of the main grounds is, forward part of the door jamb.

The reason I show and ask this is that I do not have a complete wiring diagram for the car so I have no way of following a wire from its beginning to the end.

This one shows it plugged in. The orange always has power even with the Ctsy/Clk fuse pulled. The pink/white wire only has power with the fuse in. With this plugged in and fuse in I get my voltage loss. I don't know that the pink/white wire gives power too when plugged it. Strange that it plugs into an orange wire too. The plug behind this is also part of the double plug but does not effect the voltage loss and is not plugged it here. The blue wire plugs into nothing. The last photo shows the double plug, male end. There is an open for the blue wire on the male plug.


This is the same as the upper only with my thumb in the way. The blue wire plugs into nothing

 

And I don't know where the antenna relay is. I took out the power antenna and putting a simple straight antenna in so not sure if the relay was on the antenna originally or not. I can't even find the plug in for the old power antenna either.

I would unplug the radio and see if it helps

 

No radio in it yet but I appreciate it.

 

what doesn't work with the plug unplugged?

 

Thanks. I did manage to get a complete shop and electrical manual and found my problem. It was the speaker relay. When I unplugged it my current draw stopped. The car didn't have a radio when I got it but when I traced the wires from that rear harness circuit, I saw the wires that were hot and traced them to that relay. I can live without the radio for now. It still has all the bose speakers though so will try to put in a stock radio that still kinda works.

Awesome you solved it

 

Its been many years since this car has been on the road. I bought it with no drive train, cracks in both floors, a hole in the hood for a carbed engine no longer in it and more. I shouldn't have but I enjoy bringing cars back from the dead. Thanks for all the help and I know there will be more questions from me.
