MERCURY SABLE BATTERY PROBLEM

1997 Mercury Sable • 100 miles

Radio and other auxillary lights (dome light, etc) is draining battery. Do we need to replace the universal relay switch under the battery?

Universal relay switch?

You need to put a amp meter in line with the negative cable, remove fuses one by one till the draw goes away. Then you need to trace down the circuit to find the failure.

Dont throw any parts till you find the failure.
