Found someone listing a remanufactured Duralast DL7001 60 amp alternator on craigslist for only $25. www.autozone.com/batteries-starting-and-charging/alternator/duralast-alternator/333153_191428_10654/?checkfit=true He is local and willing to meet at AutoZone to confirm it works. I punched the part # into the website and it confirms it fits my '71 w/383. I'm assuming this is an upgrade over stock which is what....45 amps or so? The problem, the pic shows it only has one field connection. Is there a quick, approved modification for this? Without butchering up my new wire harness? |

it can be modified to work like two fields. Drill a hole on the opposite side of the grounded field ( blank space there ), and install an isolated brush assembly there. I have the instructions around on a diagram... Will search and post.
Don't expect a GIANT improvement on output, but, mostly sure better than the one you have on car ? Yes. I think you are winning a bit more with the smaller pulley included on alt, than the output itself.

Actually the CORRECT alternator for 70/71s got this back housing already casted with this provision, no a simple hole drilled, but this are not really common to find, so modify an earlier one or install a later one ( squarebacks ) uses to be the way to replace an alt for these years. Some STILL with the grounded brush provision ( circled the cast provision for the second field )  Some other WITHOUT the grounded brush provision  I even have found roundback replacement alts not casted but already DRILLED for it at some shops. |

Need to get this brush assembly If you are able to get just the one of the left ( holder, washer and brush itself ), will be great...if not, full set and keep the right ones as spares of the other one.  |

Hi Nacho, I'm still confused as to what to do exactly...
I have the single field casting with the 2nd. grounded brush provision on it.
So you just remove the screw and add a brush and isolate it and have a terminal there as well for the 2nd field wire to connect to?
Thanks!
PS I was wondering if it matters which field wire goes to what terminal? Are they interchangeable?

So you just remove the screw and add a brush and isolate it and have a terminal there as well for the 2nd field wire to connect to? yes, drill a hole on the opposite side ( blank space ) for the isolator/brush assembly and a small hole for the retaining screw ( just like the 1st pic shows on 2nd frame pointed out with the red arrow ) and you are done. Can't tell the size of the drill needed. This hole will show the rotor track for the brush, just like the grounded provision. PS I was wondering if it matters which field wire goes to what terminal? Are they interchangeable? either one will work in no particular order |
