buy yourself a FSR Final stage resistor. instal it yourself or have your mechanic instal it. should take him less than 30 min.

When it goes bad it will draw power and leave you stranded. We recently replaced a battery, problem continued, part store said it was the alternator so I replaced it. very pricy BTW. Still would find the car dead every few days. Changed the FSR and now one month latter no more dead battery. Part was about $70 on Amazon. $150 at dealer.
