Ive discovered an issue by accident.
Son diddnt tighten Alternator bolts up only tensioned it after belt change.
I have a switch installed to control alternator charge cycling I only use it during accelleration from stop and on ramp merges etc.
Getting to the point with a fully charged Battery last night the alternator belt squeeled every time I hit starter button and even when I roll started the car.
I went to O rileys and they tested and printed out my charging system spec's- everything was great.
This got me thinking, that the regulator is too sensitive to the amperage drop from head lamps and or starter motor.
Or, it automaticly cycles on at start up from engine management system. I would doubt the latter but dont want to dismiss untill proven.
The situation was quickly remedied by shutting off alternator.
But imagine the case of cold starts etc where before engine is even leveled out the alternator is loading it up.
Im thinking a Large Capacitor would be a best fix here because Ive already got an oversize battery, and charging system is a steady 13.2vdc.
Now For the complex question what size capacitor should I install? I have 3 old beer can sized ones 125000 mfd?? not sure Ill look l8tr.
