Hi all,
I have a 1970 Monte Carlo That has a 1.4 amp. Drain on the battery. I have traced it down by pulling the fuses one at a time to the clk\ctsy\Ltr. The CLK is the clock, ctsy i think is courtesy Lights, But what is LTR and why would this call for a 20 amp fuse. The clock does not work so this may be the drain, not sure. Under this dash is no place for a six foot tall 250 lbs 70 year old man. Before i try to unplug the clock i would like to be sure that this is the problem. Anyone have any ideas. Thanks de old bill T

LTR----Cigar Lighter

Any one of these could be a possible source of the drain---
Most likely candidate to me would be the lighter----crap in the receptical could be a path for power to ground.

Also---if you are checking the ctsy circuit with the door open---you would get a draw,----Headlight switch may also be a issue as this circuit is also grounded at the switch/dash dimmer.

Clock may be shorted????

pull the fuse with the biggest draw----doors closed---dash lights dimmed

Are you checking draw at the battery----battery--meter--pos batt cable??

Another source of a drain may also be failed diodes in the alt.

Hey thanks Bryan that helps a lot. Gives me somethings to look for that i had not though of. I was using both a volt ohm meter and a test light. I could see the test light while i was still in the car. I was testing the drain at the battery. Thanks again Bill

Doc here,

The most likely suspect is someone added an aftermarket device on the cigar lighter that is drawing current. check that line for splices and follow it down.

Make sure all draws are off, domes, glove box, hood lamp, trunk lamp, ect..all will draw current..also be sure any power antenna is not stuck in retract mode..(unplug it) high power audio amps left on can also cause this.
