i have a power drain on my 3 door cosworth.

3 new batteries, alternator has checked out excellent, all lights off, stereo off, etc.

had an auto electrician come and he said it was the alarm. so i had a brand new clifford with autostart and everything.

still does the same can someone tell me how to do all the work myself and find the drain if i buy a multimeter?

anyone got any advice or suggestions?

please help and all the best to you!
