Electrical, Alternator, Regulator. I don't know

Postby speedy1 » Sat Dec 24, 2011 8:18 pm



Today was rather nice, so I was going to ride the bike. When I cranked it up all was well, battery strong and bike fired right up. My headlight was shinning on my truck and I noticed it would get dim then bright. The volt meter was going from 12.1 up to 17. something volts and the bike's rpm's would surge according to where the voltage was. As the bike warmed up and idle came down to normal it was still doing the voltage swing, but not as bad. So being afraid I was screwing something up I cut it off.

I suspect this is an indication of something going bad with the voltage regulating department on the bike. Some thoughts on this would be a big help. Yep I know it's Christmas, so take your time and enjoy the holidays. From our house to your house Merry Christmas and Happy New Year.FL

Sounds like the regulator is going bad, its internal.
While you're in the alternator, replace the brushes and the rectifier.

While reading your post, I was thinking the same thing as the regulator. I dont exactly how to test it yet, but Im sure there is a way.

On the GL1500, the regulator is built into the alternator, just like a car. It's not a discrete component that you can test/replace separately like in the older Goldwings.

I agree that it sounds like a bad regulator. You're likely going to have to pull the alternator, and either service it yourself, or take it to an alternator shop.

You can also just replace it with an aftermarket alternator like a Compufire, that will give you massive amounts of available power, to allow you to add more accessories to your bike.

Another alternative, now that I think about it, is to replace the alternator with another OEM - and I have two used ones for sale if you are interested. :) :)

Thanks for all the replies. It looks like just replacing it may be the way I want to. Thanks Wing Admin for the offer on buying one of your used ones. I will keep that in mind for sure. The Compu Fire are pricey and I"m not really sure I need all that extra power and having to change battery as well.... Oh well where is Santa when you need him..

I use a two meter test to check for volts and amps.
The volt meter to check the volts being sent back and an amp clamp to make sure the amps aren't being exceeded with the rpm increase.
Without the meters it's easier to remove the unit like Wing Admin suggested.

Got my alternator in from Mr. Heming this evening. Started putting the wires back on and I have totally forgotten where the wire with the black looking square box goes. Does it bolt to the bolt where the condenser bolts to the alternator.. I knew I should have taken a picture first.. Go ahead I've already called myself that...

Looks like the black wire with a yellow connector bolts to the same place the capacitor bolts to witch is the same place the positive battery cable connects to.

Thanks guys. The picture really helped and that was the way I had put it back. Sometimes you just doubt yourself. Glad to report it is all back together and the alternator is doing as it should. No noises coming from it either. Thanks for the help and thanks to Mr Heming for the alternator in quick fashion.
