I just bought a 2004CBR1000RR and the battery died and had to be rolled off. I thought everything would be fine. Well I charge the battery some and put it in and hold the contacts to the battery and have my dad start it and let it run a second and the take my hands off the contacts so I can test the regulator and stator. I'm new to all this by the way. I believe that tells me it isn't the battery's fault for going dead. My question is; is it most likely the regulator or the stator.

And could somebody please recommend a good service manual. It didn't come with one and I NEED one. Lol.

Thank you, Nathan.

 

Nevermind. This will probably just **** people off. I know how to use the search button and I know about electrical stuff. I've been to school for it. I read a thread about the 04 stator recall and I'm working on that now. I just have to take the plastic off and find the regulator and I know the stator is somewhere in the motor. Lol. Thanks anyhow.

 

battery needs to stay connected when the bike is running .. its not liek a car if you disconnect the battery and it dies then its the alternator..

bikes dont have "ALTERNATORS" stator/rectifier is not really meant to 'charge' the system .. but to maintain it plus minimal extra..

connect everything the right way ... charge the battery for 48 hours so you know its properly charged.. and get a good ohms meter

 

It is both ... you gotta change the stator and rectifier. Do not accept Honda's replacement. Spend $250ish and go to THIS PLACE . I have had mine since 12/07 and no longer get the damn near dead battery syndrome every time I crank it. Also puts out way more power ... even off idle. The Honda rectifiers and stators are crap ... rest of the bike is flawless ... go figure?

 

Thank you to both. I have a fluke 87V too. Should be good enough. I appreciate you all. This seems like a good forum. One other question....Is a regular car battery charger to much for a bike battery? The lowest it will go is 10 amps.

 

10 amp charger is o.k. but you have to time it. If the battery is completely dead then charge with 10 amps for 4 hours. If it is just weak then charge for no more than 2 hours. It would be better to have a smart trickle charger. You can get them for around $30 or so. Worth every penny.

 

+1 what he said .. and NEVER NEVER NEVER jump a bike off of a running car.. you can and 99% of the time WILL fry the ECU .. an OFF car can jump a bike and still have enough juice to restart itself

 

Toptaz-

I have nothing against you and I'm honestly not trying to start a flame war, but I'm wondering where you're getting this information. The CBR1000, just like a car, has a charging system that can recharge the battery and power the lights, ignition, fuel pump, etc. As is the case with cars, if you have a deeply discharged (but healthy) battery, the CBR's charging system will supply a charging curent that's well above the battery mfr's recommendation. Yes, our bikes can charge the pants off of these poor little batteries.

How will jump starting your bike from a car fry the ECU? You might fry the battery, but unless you're jumping the bike with a 24V diesel truck or something, the ECU should be fine.

Where am I getting my information? My garage. Inside it numerous tests have been conducted on a 2007 CBR1000RR withtwo Fluke DMMs, an oscilloscope, a Dataq DI-148U data logger, and an electrical engineer.

 

i dont take anything personally ... we are all friends right ?

ok ...
1- most people dont understand that the 'out put' or 'charging ability' of the cbr or any current sports bike for that matter (going back to mid 90's) only output above 4-5000rpms which means under load conditions... NOT sitting in a driveway... unless you are going to hold your throttles over 5k in teh driveway... (ugh.. not that i reccommend it) .. just RIDE IT

2- you WILL FRY the ecu if you jump it off a running car... mainly cause a STATOR is NOT an alternator.. has to do with output ...

3- this information comes from a few places...
a- been working on bikes since 1989
b- had MANY conversations with the RD AND the TECHS from CORPORATE honda, yamaha and kawi
c- personally have fried an ecu or 2 before i learned my lesson
d- have seen about 12 guys do the same
e- worked in more than 1 dealership as sales manager... tech... and service manager throughout the years
f- i have5 cbr1000rr's that i own ....18 that i have worked on for custom jobs...

when it comes to the cbr1000rr there are people that know a few things about them more than i do ... but certian things i know are true and fact ..

you can jump it off a running car... and WHEN you fry the ECU .. it will not get covered under the honda warentee (hence another way i know its not good to jump it off a running car)

an OFF car you CAN .. and i WOULD .. running car.. i would not

 

I dunno about the running car bit ... but the stock electrical won't charge the pants off a AAA battery [8D] It truly is Honda's one weakness ...
