1500 alternator removal

[jbeganny]

I need instructions on removal of the alternator on a 89 1500.

Heres what the book says.......

It's not really hard. Just be sure to have the everything oriented correctly when you begin to install it, or it won't fit in properly. Best to take pictures before and during removal so you will have reference for installation. When I changed mine (several times) I did not disconnect the wire going up into the shelter cover. Instead I disconnected the end that is on the alternator and then connected it to the new alternator. I believe it is a noise filter. It's the little black component with the green and black wires.

The hard part is gettign to it..once you have the engine out the alternator itself is easy just a few bolts and wires.

That said, on the GL1500 the alternator can be remove and replaced without removing the engine. It's a tight fit, but it can be done.

Helpful trick is to use a video camera while removing alternator from bike. The roll and twist can be recalled for easy install. Made it a 30 minute install on my bike.

After a problem I had with a alternator rebuild that did not work, I have had the pleasure of r&r the alternator on my wing 4 times. If it goes well you can do it in less than 20 minutes. But if it doesn't go well you can fight it for 45 minutes or longer! You DO NOT need to remove the negine to replace the alternator!

I should have mentioned this in my first reply, you should change the rubber bushings or shock absorbers (I forget what Honda calls them) that mate the drive to the alternator. If the connecting piece between them breaks you can still use them if you don't have a replacement. If they won't stay in place during assembly a little dab of grease will hold them in place while you put the alternator in.

Alternator dampener. They're relatively cheap ($17), and available in stock from Cyclemax, so you don't have to wait for a Honda parts house to order them: GL1500 Alternator Dampener Kit

I got old one out easily. Putting in new one I must have messed up altho I thought it went well, I have an oil leak so must have pinched o ring. I think I should put grease or something on o ring before install again so it slides in better. What do you think?

[Erdeniz Umman]

I would order a new o ring and replace it.
Don't try to over torque the bolts to prevent oil leak. Or you may end up with a broken mount like below.

Have another o ring. I torqued to required 22 ft/lbs.

The wire that goes up.into the faring where does that plug in?

[bellboy40]

I think you mean the wire that goes up to C43 from the alternator. The small wire (blk/lt grn) goes to C43 located on a row of about 6 connectors mounted near the left side of gas tank. It is a white 2 pin connector.

[ETNTHEMADCHINAMAN]

Yes that's the wire. I just took it off from the back of the alternator for now but when the new one gets here I wanted to replace it because the old one looks pretty cruddy. I read somewhere you have to remove half the fairing to get to it so not looking forward to that lol.

[bellboy40]

Yes, you have to remove several pieces of the fairing to get to those connectors. Not too bad a job though, it just takes time. Some of the DIY articles on this forum explain how to get those pieces off. Here is one showing how to get to the sub air filter and cruise filters. It explains what needs to be done to get to them. You will only need to take off the left side fairing pieces for what you want to do. Since you are that far into it though, I would go ahead and take it off both sides and replace those filters if you haven't done that lately.

I managed to just take the reverse handle off and the stud at the bottom after taking the dash and seat off I was able to get me hands up in there to change the wire. Probably not the best way but I didn't remove the whole fairing piece.

[bellboy40]

Well, if it worked for you, that was a good way.
