What Model Year is my GL1500?

Postby GBKid » Sun Jul 10, 2016 8:00 am



I own what appears to be a 1989 Honda Goldwing. During recent repairs/maintenance I have performed, I am beginning to suspect I have a 1990 model. When I purchased the bike it was advertised as a 1989 model and titled as such. The VIN sticker near the radiator cap says it was manufactured "5/88" and "1989 Model". However, I am about to undertake replacing the alternator and while shopping online the 1988 and 1989 alternators are different than all of those manufactured after 1990. Yet, Hitachi LR140-708, which I believe is the original installed on my bike, is the 1990 and later years part number. Can anyone explain this? Thanks.

Also, I'm looking for some advice when a 90 amp alternator is actually needed. I only have the stock electrical equipment, plus Show Chrome driving lights, Garmin GPS, and an IPOD.

Can someone also tell how to diagnose the problem so I am certain it is the alternator not charging. The battery is a Honda battery less than a year old that is always kept on a battery tender.

Is the vin number on the title the same as what's on the frame? Also it could be someone replaced the 1989 engine with a newer one.
What kind of symptoms are you experiencing that makes you suspect your alternator?
More info would help and I'd bet someone on here has experienced it before. :)

I don't see at least 12 v at either the large or small wire at the alternator with the engine at idle. I see 12.7 v at the battery and alternator large wire, 0 v at small wire with the ignition off. 11.6 v at the battery and alternator large wire and small wire with ignition on. 11.6 v at alternator large and small wire and battery with engine at idle. Seems like alternator to me. What do you think?

It could be the alternator. But it just occurred to me most auto parts houses can test batteries, starters, alternators, etc.
Call your local parts house and ask if they can test your alternator and if you need to pull it out, or if they can just hook their leads to your battery and check the charge with your bike running.

Can use a battery tester to see if its battery or alternator. Not too expensive at Harbor Freight, $22. Just clamp to battery, also has a load tester.

Using a voltmeter, check the voltage across the battery with the ignition off. The reading should be between 12.2 and 12.7 volts.

If you can hold the voltmeter across the battery and start the motorcycle at the same time, you will see the voltage drop to a lever around 10 volts while cranking the engine over IF the battery is fully charged and in good condition.

If the voltage drops to 9 volts or less, the battery is weak and should be charged and load tested. A replacement will no doubt be in your immediate future.

After the engine is running and above idle speed, the voltage across the battery should be between 12.9 and 13.9 volts depending on the accessories that are on.

If the voltage is below 12.2 volts and all your electrical leads are tight and clean, the alternator is not charging and needs to be repaired or replaced.

All alternators made to fit the GL1500 will fit all years of GL1500 from 1988 to 2000.

If you want to know more about the Goldwing History and different models for each of the model years up to 2004, take a look at this site: http://homepage.tinet.ie/~wingnut/goldwinghistory.htm

More likely that you do have a 1989 model, built in 1988, and that sometime in the past 27 years, someone has replaced the alternator.

That makes the most sense. I replaced the alternator 2 days ago and all is right in the world again. It runs great. I also noticed that now when I turn the cruise control to on, the "cruise on" light immediately illuminates where before it took several seconds to light up. All of the lighting is a little brighter too. The alternator probably was putting out just above 12.5 volts for awhile before it finally quit. Thanks WingAdmin and everyone else for your input. This site is really great!
