Looks like the alternator on my '04 Brutale has finally died. It did start to exhibit issues a while back, but then the charge light illuminated and it went downhill quickly from there. According to the tests both from experience and from the service manual, the generator no longer generates.

Does anyone know of a good source for a new one? Someone reliable and - possibly - in the US?

Thank you in advance!

I'm breaking down a couple of gen1 MV's and have two.

I'm in NZ so will be a little bit of shipping, but not too much - send me a PM.

Cheers
Tim

They can also be rebuilt...it is an automotive alternator by Denso...same as many small Japanese cars. Take to an auto electrical shop.

Bet it's not the alternator........
Your bike is 14 years old.......things corrode
Remove the negative battery cable and clean it, use dielectric grease
Do the same to the positive terminal
And both sides of the 4 wire plug, 40 Amp fuse and plug, the alternator wire and terminals
Don't forget the engine ground

Reconnect everything and get back to us

:wink2:

Jumped too far...

All,

First, get a life! Come on! NO, I am seriously kidding there...THANK YOU very much for responding so quickly. I am always impressed by the membership here and always get the information and/or instruction I request. Truly, thank you. (Maybe you can tell that I have only one shop which I trust locally and no MV dealers closer than four hours away.)

As for the electrical connections. The first bits I checked were the battery - new, but you never know - and then the ground because I have actually recently given it a good clean. I went ahead and looked at the fuse (or so I thought) and the CDI unit. I then went through the testing procedures in the service manual. That is when it led me towards a replacement alternator. I jumped here to search for a good supplier and could not find anything via the search, so I went ahead and posted...before I did more research. That's when I found out that some decent auto electric specialists can rebuild them. So, that was going to be my next step...

Well, after getting the usual good advice of running a systematic series of checks on this board (yes, I'm addled of mind and humbled by those present here), I discovered that I had not actually pulled one of the 40A fuses to get a good look. I was not thorough and it almost cost me. Turns out that the fuse I had not examined closely enough (the one closer to the battery which must be the charging circuit) is fried.

Thanks to theknurl and esq'z me for the tech info. Thanks to cruiser for the offer - I am looking for a couple of replacement pieces, so I will PM you soon.

My next question, if you do not mind, is should I worry about what caused the fuse to do its thing? Or, should I only truly be concerned if it burns through the replacement quickly?

Cheers,

Jon

See what happens to the new fuse before jumping to any conclusions. Could have been a momentary short circuit you created while working on the bike once before....or anything that touched the wrong spot one time.

If the new fuse blows quickly then it is time to start investigation.

@quixotic_1: We actually cannot tell what dealerships you have near you simply because we have no idea where you are. You can fix that easily through TOOLS>USER CP>EDIT YOUR DETAILS. You can also add your year and model to your signature line. This helps members help you with local information.

As for the fuse (replying to esq'z me):

I figured that it would be good just to keep a close eye on it and see if it blows again. She has been through her share of electrical issues in her life and I have experienced some occasional headlight dimming, which could be a good indicator that something was wrong previously (this had, at first, seemed to be a bulb issue and I had a new bulb I was carrying just in case).

So, I will add the fuse check to my monthly chain clean and lube and basic fitness check (battery charge, electrical connections, nut & bolt check, etc.).

As for the location (replying to silentservice703):

I did not know that my location was not here. It has been more than ten years since I signed up, though, so it is entirely possible that this was missed somehow...I will fix it immediately.

Thank you all VERY MUCH!
