Re: Battery ?

On 70 El Caminos & Chevelles it goes to the core support, Just to the right of the Batt. You will find a terminal block (on the core support) with a small nut and a wire attached. When you attach your + wire to this, It will feed 12 Vts. to the interior, Ign.--lights-- fuse block,-- Horn relay,etc. Now you will say, OH S#!T, Now I remember.

Re: Battery ?

The relay on the drivers side is the horn relay.

Re: Battery ?

What you are calling a "short" in the horn relay (current drain) could be something upstream since the "BAT" terminals on the horn relay serve as a terminal to feed power to the bulkhead connector, then onto several other things.

{EDIT} Guess that would be downstream, not upstream.

Re: Battery ?

There's no such thing as a "12 volt draw".

Current is a draw, typically measured in amps for automobiles.

A 12 amp draw would be quite considerable and drain the battery very quickly.

The set-up works like this:

A 14 ga. fusible link from the battery (+) to a junction block behind the battery powers everything in the car but the main starter power feed. At the junction block, the fusible link meets up with a 10 ga. red wire that runs across the radiator support to the horn relay which has screw terminals and splices that distribute power to all vehicle components.

-If you don't stand for something, you'll fall for anything.
