i attached my voltmeter to the battery post while the car is off, and i got 12.65 volts, once started i got around 14.75, with minor fluctuations. i increased the load by putin every accessory on. not to much difference... i even put my system on, cause i know that causes dimming, just to test. on low base notes i'd drop to 13.## and jump back up. i reved by hand, and noticed that at one point it spiked to 15.## volts
now the oddest thing was when i reved very lightly with most of my accesories OFF, except maybe the heater, there was a momentary loss in voltage right down to 12 volts... and i could actually hear the loss.. then it spiked back to 14.. and i could repeat this by reving very light aprox a quick tap to 1500 - 2000 rpm
Is that normal? or do i need a new voltage regulator/ alternator/ both?
PS: now keep in mind i couldnt see my tach, so it may be possible that my rpm droped lower than 750 when i lost voltage.
