Just to be sure,borrow another meter and check it again.It wouldn't be the first time a meter was wrong and the bike is OK.
If it is in fact that high,pull the alternator out and have it checked.The voltage regulator lives inside it.

Yep, what Virgilmobile said. Will cook the battery, and hard on bulbs etc if it is truely that high. Sure sounds like the regulator.

One other thing to quick check too.measure the volts on the sense wire that feeds the back of the alternator.The little wire.It should be the same as the battery.Off hand,I don't recall if that plug has a ground wire in it...better look.

Thanks for the replys I have the alternator out of the bike now. I was foing to take it apart
since i hace a meter and shop manuel but decided to take it to a shop for testing. I forgot to mention
that on 2 occasions last season bike died and needed a boost to get going again but seemd fine
for a few weeks then died again. Any on suggest a rebuild or replacement? Can get alternators from
e bay much cheaper than stock any suggestions if i decide to buy a new one?

Have it tested.Explain to the tester that your meter showed improper volts.
DO NOT hint that you measured high voltage.See if they test it that way.
If its bad.you have a few options.rebuild it your self,send it off for rebuilding,order a Comp U Fire alternator,go to your local alternator shop and have them take care of it.

I installed a rebuilt alternator that worked well for a while. Then it began overcharging and died completely shortly thereafter. You should probably start searching for a replacement alternator.

Beware of the cheap Chinese alternators on fleebay. Others have had problems with some of them. The only ones I can recommend are the Compufire or Ken Hemming rebuilds or makes higher output alternator for the wings see the link above.

I bought a couple of Alternators from these guys: RZ Alternator & Starter in Harbor City, Ca. They offer a 90Amp alternator for the GL1500 at a very reasonable price.
There number is 310-530-6410.

I've installed their GL1500 hi-amp alternator on a couple of bike in our GWTA chapter, haven't had any problems with them at all.
