Hi everyone am a new member, i would like to ask if anyone can help me. I bought a cbr600f2 off someone rode it home, the next day went to it and it would not start, so i thought it was a flat battery took it home and charge it. Put it back in the bike and it started it got me to work in the morning and back in the after noon went to start it but no joy, i then went and bought a new gel battery put that in and it started yet again failed, now all i have the battery fully charged /all Fuses are ok front light dim no indicators work /horn sounds low and when i press the start button the is no clicks nothing
Many thanks if you can help

 

Welcome to the forum Steve.

Sounds like you may have a bad R/R.
Here's how to check it.

Charge the battery and make sure it will start the bike.
Disconnect one of the battery terminals and let the bike sit at least overnight.
Reconnect the battery and see if it starts. If it does the R/R is bleeding down and needs to be replaced.

 

Welcome to CBRF! I second the R/R theory. Another way to check is testing the voltage while bike is off can when running. The voltage should jump up 1-2 values if the R/R is working correctly.
