hi everyone. i just joined this forum because i need some help. i just got my first bike ever and i was super excited to ride. and within the first couple of days i started having trouble and getting very upset. the bike seems to not start on certain occasions. the first time i was at a light and the bike shut off on me. being a new rider i thought it was me. but as i tried starting it it wouldn't roll over. so after killing the battery from trying to restart it so much i recharged the battery and it started up fine. i didn't think much of it until it just would start the next day at my friends house. not even trying to roll over as it did before. i got the trickle charger and after about a half hour it started. after research and reading i think it is something electrical (rectifier regulator, stator, battery,) or even the carborator. any suggestions? i am not much of a mechanic, but i learn pretty quick. thanks

 

What kind of bike is it?

 

It is a 98 cbr 600 f3

 

My money is on a duff battery. Possibly caused by a duff regulator/rectifier.

If you don't have one - borrow or buy a multimeter that will measure at least 30vDC and 40vAC

When the bike is running - check the voltage across the battery - you are looking for somewhere around 14 to 15 volts.

Do this check at tickover, then at 2000rpm, then at 4000rpm

If that is OK then the battery is toast.

If the above test shows low voltage - you need to find out if it is the R/R or the generator.

Unplug the 5 pin plug from the R/R.

Start the bike up again.

Set the multimeter to AC volts and test between the three yellow wires in pairs.
Between any pair of yellow wires you should see around 26vAC

If the above test is ok - your R/R is toast

if the above test is low voltage or one pair is different to the others - the generator is toast.
