Think of it this way...Don't wanna hijack thread but I have a 78 GS750 that I just recently bought,
It has a new battery, a new Mosfet R/R but the original Stator. I'm still waiting for my Dyna S in the mail,
Do the original stators have a shelf life? I'm in the middle of getting the bike up and going and am wondering if I should replace the original Stator just so I know that everything has been covered for the charging system, including all the bullet connections.
The original stator is 36 years old. That's 36 years of being exposed to acids, corrosives, heat, oil, vibration, mechanical shock, and electrical misadventure. That's a lot to ask of the varnish/insulation of the 1970s.
Which is why I'll be replacing mine with new ones, made with 21st century varnish/insulation. I'll get what I can out of the old ones, but I suspect their end will come sooner rather than later, and if left on the shelf, they'll just deteriorate eventually.
