What has to happen to get an NA alternator to work in an MSM NB. I got a MS2 with a known charging issue. Previous owner said he swapped in a NA internally regulated alternator and all was well in the world.
What wiring has to change? I found some threads on the NB wiring but nothing MSM specific.
Thanks!



I know.....fix the MS. Well im not that MS savvy and dont want to complicate an easy work around.

Thanks

Think I found it. Sound right?


You'll also need the harness pigtail for the 94-97 alternator.

- The big white wire is the same for both units.
- There's a 2 wire plug in the 04 alternator with a grey wire, and a grey / red wire. Cut off the 04 plug, and splice the grey wire into the white / black wire of the 94-97 pigtail. Next splice the grey / red wire into the white / green wire of the early pigtail. Plug it in to the alternator when finished..
We have to move these wires, but we'll do it at the ECU plug (under the dash, by the steering column) where they're easier to get to.
-The grey / red wire goes to 3M at the factory ECU plug. Cut it off, and splice the harness side of the wire into a switched 12V source from the main relay.
-The grey wire goes to 4T at the factory ECU plug. Cut it off. Also cut off 3U (brown / red). Splice together the harness ends of 4T & 3U. The ecu will no longer be controlling anything with the alternator and you should now be seeing 13V continuous.
