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?
I reposted this here after no response on the JD forum, hoping to catch a couple of the experts who might not dig into each manufacturer board.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
