any ideas?

[armedandinsain]

ok the bike had a dead battery again last week so i stuck it back on the charger. after it was charged i let it sit 2 days,3rd day i went for a ride was fine all the way to my lunch stop had lunch started it again it sounded weak but started,5 miles down the road I stopped for gas and it was stone dead push started it and im off headed back home I got on to 917 about 2 miles from the ducati shop when out of no where and at about 70-75mph the bike lost all power and shut off tried to get it to turn back over before i came to a stop nothing. ended up walking to the ducati shop and having them pick my bike up and keep it there till i could get a ride home to get the truck back out there to load it up. the 3 guys there (that i must say were very friendly and a great help) all came up with a diffrent reason the bike would do that, but all 3 also stated they had never worked on a gsxr before. so I ask the all knowing minds here is it the battery having a dead cell,Regulator/Rectifier,or the Generator any help would be great

Could be any of the 3 issues you mentioned. You will have to charge the battery and have it tested. If it won't hold a charge then it is bad. Completely discharging it several times can also kill it. Start there. Then get the charging system tested. Most likely you also have a problem there. I don't have any equipment to test that though.

Tough call. When the R1 was acting up, I took it to Cyclewerkz and they thought it was the regulator/rectifier first, replaced that, and then had to go back for the generator. My battery was also shot because of the regulator/generator issues. I'm not sure there is any good test other than to replace the cheap one, and then move on to the next peice.

I would lean towards the regulator rectifier myself. if you have the book it gives you the ohm readings to check it. I would first check to see if the battery has a dead cell. Cycle gear , Autozone, Oreilly's will all check it for free. When you go to disconnect the regulator rectifier check the plug end for any sort of melting that may have occurred. This does not mean that it is bad though, just that there was was a spike of power that the regulator was trying to disperse. If you need a hand with that just let me know, & I will see what I can do about getting over there.
I am in the process of trying to buy a house right now, so my time is kinda limited, but I will try.

Diagnosing electronic problems...

1) Take the battery to a shop and have them load test it. It helps if it's already charged, if not they'll have to charge it first and it might take a day or two. This will tell you whether your battery is good or not. I know Cyclewerkz does this free of charge.

2) Install the battery to the bike. Put a voltmeter across the terminals. Voltage with the bike off should be in the 12-13V range. Turn on the bike and rev it up to around 5k. Voltage should now be in the 14-15V range. If it is above this, the R/R has probably failed and is not regulating the power to the battery, which can quickly fry it (if your battery was found to be dead in step 1, this might be the reason). If you're seeing less then 12V with the bike on, it's either the R/R or the stator (alternator).

3) Assuming you're getting less then 12V in step 2, you need to first check the stator. Look for the three wires coming out of the stator cover and follow them to it's connector. This might be on either side of the bike, you might check some brand-specific forums to find out. Disconnect the connector and check the continuity between each wire and ground. You want no continuity / infinite resistance. Next, check the resistance between the wires. Each pair should have a resistance of 0.1 - 1.0 ohms. If it passes these tests, your stator is probably fine, and it's most likely the R/R.

I've fried two stators on the VFR, so I've done a bit of reserach on diagnosing charging system problems...

There you go, the resident expert on charging systems! And, if you want an extra voltmeter installed on your bike, he can walk you through that too!

[armedandinsain]

sounds like I have some work to do tommorrow when I get up. I sure hope this wont cost to much

[Blizzard_1708]

Did you ever figure out your problem?

[armedandinsain]

ummmm ummmmm I got the battery out of the bike and to the table next to the bike then I got side tracked and havent got back to it yet

[Blizzard_1708]

damn, that was like a month ago. I couldnt go that long without the bike! Well, my problem turns out the be the charging system, hope yours is cheaper to fix!

[U-Turn]

Go get the battery tested - no charge usually.

[armedandinsain]

it has gone back and forth from no cash for a battery to no time to get it tested and pick up a new one back to broke

[mattjmartin]

Charging problems are a money pit usually. GSXRs are semi-notorious for cheap R/Rs, and bad R/Rs usually mean you end up deep cycling your battery several times and severely damaging it. I'd get a new battery (since you need it now regardless to maintain reliability) and then if it happens again, replace the R/R. Get one from a honda.

[sckego]

Haha, the common mod with a lot of Hondas is to swap in the R/R from an R1.

Maybe the common ground is swapping to something else that hasn't already failed on you once?!

[Firewa11]

What is a R/R?

[Blizzard_1708]

Rectifier / Regulator

[Firewa11]

Hmmm... could explain why I've gone through 2 batteries on the Gixxer...

[dufremle]

You didn't let Sparky touch the Gixxer the last time she was there, did you? She may have shorted it out.

[Firewa11]

Crap! She did! She threw my Gixxer on the garage floor!

[Blizzard_1708]

I threw your Gixxer on the floor YEARS ago! And I did not touch it last time I was there!

[armedandinsain]

ok so i went to 3 places and all of them said the battery was fine so im lost they also told me the battery could use a charge but it was still good.but i charged it before i went to get it tested so idk maybe its just time to get a new bike

[Firewa11]

I threw your Gixxer on the floor YEARS ago! And I did not touch it last time I was there!

Yes but you touched her before she started having electrical issues! OMG you're like the devil or something!

[Blizzard_1708]

If I were the devil, your bike would have burst into flames

Cyclewerkz did tell me to get mine tested while it was still practically dead, but it might not be your battery. It might be your charging system. Do you have a voltmeter? Measure the voltage when the bike is revved to 5-6k. If you dont have one, remind me to bring mine to bike night for you to borrow.
