Hi Russ, I had alternator issues (Diodes) I looked into having refurbed and found it wasn't worth fooling with. I found a shiny, brand new, genuine Hitachi (Yanmar's OEM) alternator for about $75.00- 80.00 shipped on eBay. I just put it in myself, it was a plug and play 30-45 minutes install. At least on my boat, it was one of the easiest / most accessible things to replace. The new one worked much better than my old tired one when it was working "correctly". That was 5 years ago. Never had a problem since.
When you think about it, especially if it's the 30 some year old original, the brushes are worn, the bearings are worn, the windings have seen better days.. The whole thing is worn-out. You'd have to replace pretty much everything on the alternator. After some research, I found that buying a shiny new one was cheaper than having my old one re-furbished locally. Here's an actual Yanmar brand Item for $160.00 (Pretty good price for OEM) : https://www.ebay.com/itm/YANMAR-MARINE-NEW-LR155-20-ALTERNATOR-BRAND-NEW/113838371817?hash=item1a814bb3e9:g:KtIAAOSwfX9czbyu Here's a cheaper after market option: https://www.ebay.com/itm/New-Alternator-Yanmar-Marine-2GMFL-2GMFY-2GML-2GMYE-3GM30-3JH2-3JH3E-4JH-12107/292921047799?hash=item4433747af7:g:bloAAOSwSudcL7xl Best of luck with the project.
