-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)

Put your multi meter on Ohms and "audible continuity" if you have that setting.
The meter will make a beep when the probes have less than ~10 Ohms between them. Put the meter + on the red wires and the neg on the battery neg. The meter should be making a tone showing the red wire has continuity to chassis (shorted). If the meter does not make the tone, the resistance is to great for the audible to be triggered. Then you would need someone to watch the meter for you. Now unscrew the fuse panel under the dash and lower it. Did the tone go away or resistance change on the meter? if Yes, then you are on to something. In my 71 the power for the fuse panel came up behind the dash from behind the gas pedal up to a terminal block attached to the chassis. Check there for shorts and you can disconnect the red wires at that point . HTH |
