-I am getting a constant discharge on my battery
-I wired my meter in series between positive cable and the positive post on battery (when battery is fully charged) -it shows draw of 1.97 amps -have a 1975 with 66k miles and most everything stock from what I can tell -I have taken the troubleshooting as far as I can and now stumped -in the picture if you see the two red wires crimped on one terminal that is where my draw is coming from -thought that went to relay board, so I have unplugged all (3) of my relays, both fused, voltage regulator and 3-wire plug going to alternator, still can't get rid of the draw -anyone know where those two wires go? or has anyone seen this before? thanks, Attached thumbnail(s) |

Your picture shows the red wires giving the current draw. One looks to be a 2.5mm red wire and the other is a 4.0mm red wire. The 2,5 goes to the relay board and the 4.0 goes to either the fuse panel at fuse 10/11/12, ( they are all tied together on the hot side).
To find out which one it is, disconnect the battery and just use a jumper to ground the fuse panel at 10/11/12 and then read with the meter from ground to the two red wires. If you are reading continuity, that is the wire. If no continuity, the wire goes to the ignition switch at terminal 30. As has been posted, disconnect the plug at the switch and see if the draw goes away. If it does, you have a bad ignition switch. If it doesn't, then you have some searching between the plug and the battery for the problem. Quite possibly a previous owner modification somewhere on the big red wire. Don't forget to remove the jumper used above! Tom |
