i have a 1997 madza protege-after several days the battery will be so weak it want start the car.-had battery checked and it is good,no dead cells,-alternator checks good,with lights and heater on the voltage is over 14volts.--the starter and solenoid are good-there must be a shortage some place,,maybe someone there has a similar problem that could give me some info.--ray

A good place to start is to hoook up a multi meter to the battery and remove one fuse at a time. When the battery voltage goes up you know that there is a drain. Some fuses such as one for radio, alarm and those type of systems will always have a slight drain.

Also check the following technical service bulletins: G00197. G00198, and G00396.
