Low alternator output at low RPM.

[commando1]

1967 383 w/A.C.
Stock alternator and still running points.
I still am mystified by AC electronics. Now is a good time to learn.

Problem: Typical. Low output at low RPM. E.G. headlights dim, etc.
I believe the typical remedy of going to a higher amperage alternator is not the best because the wiring is so old.

A Mickey Mouse hack would be to overdrive the alternator. Not good.

Anything I can do with the alternator a/o V.R. to increase output at low RPM?

Probably not what you're looking for but a new " updated" voltage regulator keeps my lights from dimming at low RPMs

Sounds like what I AM looking for...
So just a new VR, huh? That's something I should do regardless.

Now I have to find the thread where I showed how to rewire a new one in....

I know you probably checked, but make sure belt is good and tight.

Use the vr-706. Direct bolt in. No wiring changes.

Auto Zone etc. sells the same piece.

That was too easy....

Do you have to use an inline fuse with the vr706?

Raise your idle. Is your trunk light stuck on I know you did some work in there?

No.

Plug and play.

We could find a way to make it hard... and with that, cost a lot more money that you don't need to spend. If that's what you want......

Ok I was reading on the b body forum when I looked up the part someone said they had it burn up and a wire under the dash. Not questioning you but that's why I asked.

They probably hooked it up wrong or their wiring was bad.

Ok thanks

First thing I do with every car is remove the bulb. Lol.

No. Easy is good.
I suck at AC electrical stuff. I don't know how you cram all that info into your head.

I have a big head....

I grew up around this stuff. My Dad was a genius at this stuff and my uncle rebuilt Mopar alternators and starters in the back of his shop for a living.

You got that alternators make AC rather than DC. That's much more than most.

Did I mention the electronic V.R. was the solution.
Thank you, Dave and B.J.

Your welcome for my smart assed comments. LOL.
