5500N alternator question

I was trouble shooting the non-advancing hour meter on my 5500N yesterday. Following the Technical manual instructions, I got to the step to verify alternator output- had battery voltage at the big lead and also at the IG terminal with KOEO. When testing at low idle, I had no voltage at the L terminal, which feeds the hour meter and charge indicator light. I do not have a charge indicator light lit in either condition. The tech manual says voltage regulator failed, replace alternator.

This seems reasonable, I guess. The battery has been staying charged and the other electrical items seem to function correctly. I did not take a voltage reading at the battery while it was running.

I can get a reman on prime for under a hundred, or on flea bay for $125, or from the dealer at $461. There is also a package on theBay for a replacement voltage regulator and brush holder/brushes combo for $35. Assuming no obvious issues in the alternator (bad bearings etc) I'm thinking it can't be too hard to swap out VR and brushes, can it?
