Higher output alternator

[Knebel]

So, with my electric fan on i constantly saw 11.9volts, even when driving. I just bit the bullet and shelled out the money for a powermaster alternator. The spec sheet says "57amp idle" "92amp cruise". Bolted the thing in and wow. I get a 13.9volt when just idling and when I turn on everything on the car it goes to 14.4 volts. Im happy with that, hopefully that charges my battery better so that its not draining all the time...

Did you bypass the ammeter?

I have put a second wire directly from the alternator output to the battery. Its more of a short mock up at the moment still have to replace that with a thicker wire and fuse. I might be doing that tomorrow.

I know I am YEARS behind in this post but I too am looking to upgrade my alternator to a 60amp on my 69 300. I read your thread just now and judging from your last post in the thread your 60amp is working good. I want to ask is it still working? What kind of alternator did you get?

The question I always ask is "do you really need to do this?"

Do you have extra current draws like a stereo amp or electric fans? If you don't have things like that, there's no reason to need a higher output alternator.

Yes added a stereo system. I have two amps mounted in the trunk. I was told to get the 110 mopar alternator but I don’t think I need that much I really don’t wanna have to change out all the wiring and everything I feel like a 60amp is sufficient and i can still keep the regulator installed with it
