73 mustang

i have a 73 mach 1 and i'm having a little electrical problem. when i drive it during the day it does fine, but at night when i have the lights on it kills the battery. i changed out the battery, alternator, regulator, checked for electrical leaks but i still cant get to the bottom of it. i know its a small fix but i dont know what it is or where to start. so if i could get someone to give me some pointers or lead me in the right direction i would greatly appreciate it. i have tested the battery and the alternator. i have even switched them out but it still does not want to work right.

Re: 73 mustang

New parts doesn't mean they are good. Don't just replace parts. Places like auto zone and advance test them for free. Also check connections, especially grounds for good tight and clean connections.
