I disconnected the positive cable to run a amp meter to find a draw.Than I remove fuses one a the time to find the draw.Since then,I cannot get the central locking system,trunk switch and alarm to work.I did go back and checked every fuses with voltmeter,but still nothing.What could be the problem?Also I have replaced the valve cover gaskets,but I still have a leak at right rear side (lowest point).No matter what I do,it still leaks?
