CBR600RR no longer starting

Motorcycling

Hi all,

I’m busy debugging an issue with my CBR600RR. For the past month or so it has had trouble starting on occasion, usually after I’ve just ridden for a while, turned off for a few minutes and then try to start again. A common scenario would be when filling up with petrol I’d be unable to start again after paying up.

It would turn of initially, and following that there will just be a clicking sound coming from the general seat area. The dash also starts to go crazy. See video:

Does anyone recognise these symptoms and have any suggestions on what to start trying to troubleshoot this?

Many thanks,

Jamie

i may be as simple as an imperfect contact (oxydated fuse maybe)… give that a try before starting to check the relays… also check if the battery is within the normal limits (amps and stuff)

3

Wow check all the connections along the live circuit

4

It almost sounds like a dead battery but i’ve never heard a starter relay clicking that fast.
I think it’s OMC time…

Sounds like the battery doesn’t have enough charge in it. If you have a multi meter you could check the Voltage. Or boost it with the bike next to it and see if that resolves the issue.

6

Does it start with a push?

7

Loose battery connections?

8

Sounds like a flat battery to me.

Also, there is a small black connector behind the dash unit that goes to the main loom. Make sure that is firmly seated. (You might have to displace the nose cone to gain proper access to the connector)

I’d go along with the battery theory as well. Let us know how you get on.

being a honda, I bet your reg/rec is on the way out which is frying your battery.

take the battery out at the time it doesn’t work and see if it’s bulging. then check the connector for the reg/rec hasn’t got corrosion on it

11

Defo sounds like its not got enough power,

-Check battery health
-Check battery terminals aren’t loose
-Then check to make sure you don’t have a bad earth

Once it’s running I’d check alternator and reg/rec are both working as they should.

Hi all,

An update on this issue. Had the battery on an optimiser all week, connected it up today and bike starts no problem. Have run it up to temperature and all seems good.

I have a feeling I’m going to hit issues again at some point, how can I go about testing my reg/rec? And is the only way to test my alternator to buy a voltmeter?

Thanks for everyones interest.

Jamie

Do a drop test on the battery.
It might not be holding its charge

This should give you all the information you need.
Go through the relevant steps carefully and make a written note of the results.
If you’re still stuck when you’re done post the findings here and one of us will diagnose.
You certainly need a voltmeter, 10 quid from B and Q.

Its a Honda just get new reg/rec job done
Plenty on ebay. . . . . David Silver spares, jaws

16

£3 on eBay

£6 at maplin…

Scorch you made of money mate? :hehe:

17

first test is to take the connector off the reg/rec and see if it’s corroded. simple to do

18

Its for a F not RR but might be usefull
