Reads 0 amps when I have it plugged in and attached to my car battery... usually goes from the high end of the scale, down toward zero as the battery is charged up...

Reads 13-14 volts when I put my meter on the battery...

and then the battery by itself reads 13+V with the charger removed...

oh, yeah, when I hit the key, it just buzzes and won't start...

so, I guess I have two questions: what's wrong with the charger and what's making the buzz when I try to start the car?

thanks,Mark
