2002 GL1800 Goldwing...Alternator fuse??

Postby angelaandpaul » Mon Apr 11, 2011 5:11 pm

Ive been trying to find out what is causing my 2002 GL1800 goldwing to loose power. Ive replaced the battery and within 15 minutes of riding we lost power again. The meter(at the garage) says that our alternator is putting out zero amps. Does the alternator have an in-line fuse or any fuse ???

The "ignition/cruise fuse" number 19 is a 15 amp fuse in the main fuse box, which should be checked first. The 100 amp main fuse also protects the charging system.

According to the Clymer manual, the most likely cause of no voltage from the alternator, if not a fuse, is corroded wiring, followed by the regulator (after the battery has been verified to be good of course)

Anytime you play with a problem like you described a good volt meter is required. Connect a fully charged batery, Check the fuse and read voltage at the fuse block area were that fuse plugs in. If its the fuse it should show 12 volts on one side and nothing on the other. Change fuse and check again on both sides. You will see 12 plus volts on both sides of fuse. Start the bike with the meter in place. Is the bike charging at 13-14 volts. Get back to us when you have done this and if the fuse blows we can go further.

Your alternator and cruise control sytem are tied together by the cruise control fuse. If you turn on your cruise control and the cruise control light does not come on it means your cruise control fuse is blown and the cruise control will not come on and if your cruise control light is not working it also means your alternator is not charging your battery.

The only way to really know when your cruise control fuse has blown without manually checking it is to ALWAYS ride with your cruise control set to ON even when not engauged and as long as the cruise control light is on you know that cruise control fuse is good and your alternator should be charging.

If your cruise control light is on and your alternator is still not charging your battery then you got other problems. Hope this helps.
