Alternator Replacement

[Tyron68]

I need to replace my alternator. It’s on a 1969 charger, 383, AC car (double groove pulley). Any recommendations on a good replacement?

I suggest NAPA.

I'd go two blocks down from my place and let my local guy rebuild what I had...

Rebuild the one you have. If you have a local rebuilder. If not, Central Jersey Starter & Alternator.

IMO....rebuild it yourself. As it's 1969 vintage, it is likely that the brushes need replaced. If it's charging at all, the diodes are probably OK, along with the stator and rotor windings. Very likely the front bearing is going bad (noisy). This bearing is a 6203RSS single row sealed, both sides ball bearing like SKF, RBC, etc. The rear bearing is a Torrington or SKF caged needle roller bearing. Bearing costs at $10 - $15. Alternators are simple devices.....a "rebuilt" unit will be a crap shoot and you'll pay ~ $80 - $100 at the parts store and get the same thing as doing it yourself for the cost of parts.....plus the experience. Refer to the Factory Service Manual for the information..........just my opinion of course.......

Why do you need to replace it? Went bad and stopped to charge or noise?

As mentioned, it could be serviced at home with basic tools. Diodes, stator and rotor can be diagnosed with a regular multitester. No rocket science on these.

I would go HOWEVER (as usually advice) with an alt upgrade though, getting an unit able to provide more juice.
