Re: 2002 Jeep Grand Cherokee total electrical failure

When you won´t get any light on, also when opening the doors for example, then first check the battery itself. If the voltage is 12.7 V with engine off, it is ok for now.
Problems many times happen with the battery cables themselves. Corrosion at the cables under the isolation, close to the terminals can give a problem you have.
