Voltage drain

[ferretx9]

97 Jimmy
I'll start at the beginning .
Have / had an overnight voltage drop . from 12.67 to 12.22
Did the test light thing and when I pulled fuse 24 Trans , the light went out

I ran it a bit and checked it - 12.53
Left the fuse out and checked it the next day , down to 12.07

Repeated all that the following day just to make sure and the numbers
were about the same .

Basically , losing from 3 - 5 tenths in 24hrs
with nothing showing on the test light.

What should I be looking for ( other a new car lol ) ?

Thanx

You gotta check amp draw with ignition off. Then pull fuses to determine which circuit is the problem. Disconnect the negative battery terminal and hook up a multimeter $10/20. If your power draw is in the neighborhood of .0?, circuit is probably ok. If you're above .0, could be your problem area.
