Hyundai Accent GT 1996, manual 5 speed, 4 cylinder,
197 000 km. New starter, new alternator.

I enter my car this morning and put the key in the ingnition. The car try to start but a big noise came GROW!. No more electricity in the car. I try to start the car again but the key in standby position do not anymore turn the little pump, battery and hand brake light in the dashboard on. I try to test the battery with a electricity tester: Battery= 12volts, Main fuse 100amps=Ok.

Could it be my car computer who fry? Help Please!
Thank You[/align]

 

It could be just your battery. Have you tried to jump start it with another car? If you can get it started that way, it is probably the battery.

Even if it's something electrical, it is probably not your computer. There are several sensors that feed information to the computer. It could be one of those. One sensor that goes out and causes the car to run rough or not at all is the Crankshaft Position Sensor. There are also several speed sensors that measure how fast the transmission, engine and wheels are turning.

If you don't know too much about cars, though, you may need to take it to a mechanic.

 

Yes I know pretty well cars and about this crankshaft position sensor where and how i know its working correctly?

 

I've switch my other car battery in my accent and nothing appening, no radio, clock, power steering, powerbrake not a little light in the dash. It,s like the car don't want to drain any juice from the battery.

 

Maybe a bad battery cable?

 

I tested with my electricity tester all fuses in the hood and in the car, battery + cable to starter, battery + cable to alternator. But i don,t have any current to battery + to battery - cable.
