Took the 2003 cobra out of storage and noticed the alternator was not charging.
Prior to starting the car, hooked up a charger to ensure full battery.
Started driving the 40 min home and noticed 11.5 volts on aero force gauges, later confirmed 11.3V at idle with multimeter. Recharged the battery, swapped out the alternator for a rebuilt OEM I had on the shelf still only charging 11.7 at idle.
drove the car to get to operating temp, now only charging 11.3v.
battery charged engine off 12.5v, start car immediately drops to 11.7, rev engine to engage regulator, no change
checked the power distribution block, 20A fuse in spot 20 was not burned out
prior to swapping the alternator again (and having to buy a new one) what else should be checked?
thanks
