I am hoping someone can help me. I understand only the basics of automotive electrical systems. I have a 1978 Ford F150 pickup that has a 460 V8 with a stock 60 something amp alternator. The whole system is stock with an external regulator.
I am installing some high amp draw equipment and want to replace the stock alternator with a 180 amp alternator.
My only question is, do I need to replace the stock regulator? I understand that the regulator only senses voltage and I was thinking that I should not have to replace it. Am I correct? If not, what kind of external regulator do I need to replace the stock one with?
Thank you for any help.
I am assuming that you are putting the same case design in. The regulator simply sences the battery voltage and varies the power to the stator to control current output. A stock stator will usually draw a maximunm of 5 amps.
