Electrical problem
2002 Mazda Protege 4 cyl Front Wheel Drive Manual 100546 miles
----------------------------------------------------------------
I recently had to change the battery in the car, the following day the car would not turn over when the key was turned. The dash lights (warning lights) all flickered and nothing. I turned the key again and the car started. Later that day I went to start the car and nothing happened at all. I push started the car and it started right up, then within 5 minutes of driving the radio went out, the interior lights went out and the remote quit working (the remote was discovered later). When I parked the vehicle and tried to restart it nothing happened, I had no exterior lights or anything. Today the car started and has been starting, the battery and alternator all check out good. Still no radio and no int lights or remote. All fuses are good.

Was a battery charger hooked up to this car? If yes it may have caused module damage, anything over 15 olts can ruin electrical modules in your car....and a charger set on high, to either charge, or jump start it can cause problems.

There was no charger hooked up to the battery. It was simply a new battery that was added.

I would start by checking the cables from the battery, following the complete length, especially the ground cable, some of them have two points that they ground to, and I have seen them broken in half. Also check any spur wires that may be on either cable, make sure they are still connected to the body if negative and to fusible links if positive!
