i've been through 3 alternators in the past yr, i have a new duralast gold 105amp with a lifetime warrenty. Here's the problem.... when im driving and i have the headlights on and one or two more loads the Volt Gauge will drop and stay down and when my fan goes on the car gets sluggish and hesitates(sp?) AND when im racing and im near 5000rpms in 2nd(auto) the Volt Gauge goes crazy its drops and rises!!! I ahve new bosch plat +4 plugs,bosch wires, new alternator, 6 month old Diehard Gold battery, new coils and i checked all my connections...... ANYONE KNOW WHATS WRONG WITH MY BABY?!?!!?!?
