Greetings Reatta fans. I have owned my 1990 coupe for about 3 years and it runs fairly well. What I have noticed is the battery (which is a 5 year battery) will start showing signs of going bad and has been changed about every 12 months. I have tested the alternator which seems good because it is charging the system at about 14.00 volts when running with a full load. I have cleaned ground straps and battery connectors, spark plug cables and drive the car about once a week for 30 minutes. Any suggestions on why the battery only lasts about 1 year would be appreciated.
