Charging issues with Toyota style Denso Alternator

I suppose it’s because I always seem to get an uneasy feeling when I come to a stoplight and see everything dim slightly, turn signals start blinking slower, etc...that I think the car is going to die but maybe you’re right.

I am running 4AWG cable from the alternator B+ stud to my inline fuse and then to the starter relay. Voltage drop across this circuit is about 0.10 volts.

Cool, yeah, I think you are good.

To put this in perspective, I have a 2012 Chevy Cruze, and it has a "low charge mode" where the computer senses the battery is full and then will change the alternator output even while moving down the road to 12.8V. This has the same effect, slow windshield wipers, etc. When it needs to charge it goes back up to a higher voltage.
