Live wire cant find /dead battery
I have a 83 f 150 with a 5.0 and the battery constantly dies . It is brand new and the alternater is good to . I have arcing when I pull the positive cable off. I can't find the live wire or problem that is causin this. I think it could be possibly my electronic regulater. Any ideas ?

It's a Canadian thing eh!
Sounds like you have a draw somewhere killing the battery. One common one I just recently fixed was my glove box light wouldn't turn off.
If you have a multi-meter handy, pull off the positive cable and set the meter cables between them on amps. This will tell you how much draw you have, generally its never more then .3 amps or less for the computer, radio clock etc. Pull one fuse at a time on your fuse box under the hood and in the cab. Once that draw level drops down, you have an idea where its coming from based on the system for the fuse you pulled.
