[QUOTE="mastershake575, post: 8716284, member: 665251"] I'd have to look and see if the 2005 Toyotas had a voltage regulator where the PCM controller the voltage of the alt (basically what hispls said above, some cars try to have a "smart" function to downclock voltage to save gas mileage). If there is a factory voltage regulator than replacing the alt might not actually fix it since most aftermarket alternators don't bypass the PCM. Singer alternators is one for a fact that I know can bypass the toyota regulators, you can either buy a new high output alternator with the bypass built in or you can by a wiring adapter to use on your stock alternator that will basically trick the sense wire into thinking there's always a power demand so it will stay charged high 24/7 [/QUOTE]
