1969 stingray battery draining issues

found car battery dead 2 days ago .recharged and getting 14.3 vdc at battery terminals with engine running.
battery is new btw.
next morning dead battery again!
recharged and did a bit of troubleshooting.
when i disconnect the positive lead i hear a click in the dash console area?
what can the culprit be?
my next step is to pull fuses 1 at a time to narrow it down.

Sounds like you are on the right track by going fuse by fuse. That will narrow it down.

Get yourself one of those cheap electrical test lights or just make your own with a taillight bulb and a couple wires. Then remove the negative cable from the battery. Put one end of the tester on the cable and one end on the negative terminal. If you're getting a major draw the light will light. Then start pulling fuses and replacing them until the light goes out or dims significantly. That circiut will have a draw on it. Don't forget to tape the door jamb switch, the door open will make it light up cause it's a big draw.

Low in the console on a 69 there really isn't much. Some lights and the cgarette lighter. Higher up you've got lots of stuff like all the gauges and the radio. But just because something clicks doesn't mean it's your draw.

Doc here,

I suspect the click you hear may be the time delay courtesy relay, since it's located in that area.

Get your DVOM out, configure it for AMPS , set to the HIGHEST scale (usually 10 amps) pull the battery cable and place your meter in line with the cable and battery.

If you have mechanical clock, CD with presets, Alarm ect..NORMAL draw is 0.3 to 0.8 (less than an amp) higher indicates a problem..

If you have a higher draw, disconnect the alternator. Recheck your meter.. If the readings drop then (if internally regulated) your regulator diodes are bad..suggest a rebuild kit..

If externally regulated , the regulator may be bad, disconnect it and recheck. same applies..except buy a new one!

Next, If your fuse panel is WELL marked, remove ALL the fuses, and relays. Check all the fuses and relays since they are out...Then check your draw, it should be normal OR 000..If your panel is not well marked, draw a picture of it and note the fuse values/locations.

Replace the fuses one by one, and monitor the meter as you do...When it shoots up, that is your offender branch circuit. Troubleshoot , disconnect or repair as required.

As always, we assume you already have confirmed all proper bonded grounds, and power is where it should be and properly bonded.

Doc
