I have a 2005 Ford Ranger Edge, About a week ago All the electronics failed at once. When I turn the key nothing happens at all, the radio wont work, the AC does not work, the car wont turn over. The only thing that happens is that the battery light turns on but is very dim, also the headlights turn on but are also very dim. I recently had the battery tested and it tested ‘good’ and is fully charged.
In the past few months I have replaced the spark plugs and wires, starter, and the ignition switch.
Any help would be appreciated I am out of ideas on what could be wrong.
Thanks in advance,
