I replaced both the ground cables (battery and engine). Car runs great but
I still have the same problem. When I turn the car off All power goes out.
In a minute of two the car is fine and will start and run great. When I
stopped the car and had no power, I noticed that the tach does not return
to 0 but stays at the rpms that the engine was at when the car was turned
off. Also when the power comes back on if I turn the key to on (engine
not running) and off the tach goes to 0 but if I turn the key back
on(engine still not running) the tech jumps a few hundred rpms (from 0 to
about 400). I also hear a bong sound. Thanks for the help.
