Home generator died? Fix or replace?
My MIL has a Generac Guardian 17kw generator (model# 0055040) on her house. It's about 10 years old and has run well during that time. It comes on weekly/[monthly?] for its test run and has powered the house for numerous short (usually a day or less) power outages without issue. I'm not sure what the hour count is, but assume I could find out if that's relevant. She's had it professionally serviced (oil/filter stuff) annually.
During a recent power outage it died. An electrician friend came over and took a look - - apperars the generator fragged. I've not had eyes on it, but there's little curly copper bits all around the inside. Sounds like windings and internet searches seem to suggest that it happens (maybe often?).
Anyone have any experience fixing these things or ideas why it died? It appears a new rotor and stator assembly can be had for $1000-1500. I'm assuming swapping parts isn't too bad and I'd do it for her, but I dont know if there's a bunch of other issues lurking when something like this happens. Should I get it rewound - - would that be cheaper? Sould she scrap it any buy a new one?
Appreciate your thoughts. While I understand the principles, I dont have any generator buying/fixing experience.
