short circuit in the electrical system

Well my friend has this 88 GTU and the brake lights do not work.
The battery is also getting drained even tho it's a brand new one.
Any tips on how to fix it?
thanks

Lol, I think you just answered your own question...

The only other common occurance causing the main fuse to blow is shorting the alternator charge path cable to the engine during maintenance...

do a current draw test with a digital meter and start checking which fuse the problem circuit is on.
