||What else should I check in terms of the Z not charging?
Battery is full and has 12.7V out of the car.
When installed and load on it, it's at 11.89V. No fuses blown. I don't know how to "test" the fusible links, but they don't look burned.
Alternator is physically dirty, and has perhaps been whining lately.....?
Last weekend my battery was dead one morning. Got a free replacement under warranty. Not much driving in between and 3 days later, on my way to work the HICAS light came on. Was dead by lunchtime and needed a jump to get home and swap cars.
What else to check, before I start changing alternators?
My old NA had this same issue, but I don't remember what ended up fixing it. I know the fan clutch was bad in that car too.
