I am shopping for another 1500 to keep at my brother's place in Michigan, and I would like to know if there is a way to make sure that any potential bike has the earlier (Hitachi?) model alternator vs the later ones. Can it be done visually without removing it from the bike? Can anyone advise?
Thanks. Ron in AZ

How To Identify Different OEM Alternators
I'm not so sure about an inner child, but I have an inner idiot that surfaces every now and then..

Re: How To Identify Different OEM Alternators
Thanks for confirming.
However, I am trying to find out how to identify the 'good ones' from the bad physically, without removing them from the bike. An 'older' bike might have had the original replaced and ended up with a newer model. Or, a newer bike's owner may have deliberately replaced his/her original with one of the better ones.. Just trying to find an easy to make sure I'm getting a good OEM alternator.
Anyone know?
