I recently joined the failed alternator club. The luxury of having another car has bought time to work through this problem. Normally, an alternator has replaceable components that are much more economical than the alternator assembly. One wear item is the brushes, which wear out. New brushes can be purchased separately or included in the regulator sub-assembly.
Research suggests that a the TS alternator can be replaced from the top side with about two hours of labor.
In my case, with the 24V V6, a MASSIVE amount of effort is required to remove/replace the alternator. The very same engine assembly in the 166 does have an accessible alternator. However, in the 916 Spider/GTV the alternator cannot be removed without removing the front exhaust, sub-frame, etc. Many hours of labor are required.
Someone/somewhere posted a method of replacing the regulator in-place, without removing the alternator. I have failed to relocate that thread. In an effort to avoid excess work/labor, I offer success with replacing just the regulator, in place.
Disconnect the battery.
Remove the accessory, serpentine belt. Remove the lower alternator retaining bolt and loosen the top retaining bolt. From below, disconnect the wiring from the alternator. Pivot the assembly on the one retaining bolt to position for removing the black back cover. Remove regulator. Reverse process.
For the checkbook mechanic, we should be able to request in-place, regulator only replacement.
