Good day!

Well, I would say no, but I would pull out the volt meter and verify you are getting close to or over 14V when running... If it is under 13V, you may need to break out the warranty info on the alt... I have a good voltage regulator around the shop somewhere... If you wanted to tear yours apart... Not too terribly hard to do...

Cheers!!
