Ignition/total shut down
« on: 29 July, 2018, 03:16:41 PM »
Hi folks, any help with this problem would be welcome. I have a 2007 CBF1000. On three occasions recently, everything (engine, lights, the lot) has shut down/cut out whilst riding. After stopping and turning off the ignition, it starts first time with no problems. At home I checked for HISS errors but none are shown when turning the ignition on (HISS and F1 come on for two seconds then go, which, according to the Haynes manual, means there are no errors). A few times, though, having turned the ignition on, nothing has come on. After tapping or wiggling the key, the lights, dials etc do come on and the bike starts as normal. I'm a bit of an electrical dunce but I assume there must be something wrong with the ignition barrel rather than a fault with the HISS? Cheers

Check that the positive and negative leads are connected tightly to the battery terminals. The earth lead may be loose. It sounds simple but it really could be that. Hope that helps.

p.s. also check that the main fuse is securely fastened. It may be loose. I doubt it but it's worth checking. It's under the seat.

Under the tank is that spider of ground-connectors to the frame, some people had issues with that.
If you count cylinders from left to right, the connectors are above nr 3. sort off.
Just an idea...

I agree with what the others have already said and hope it's dodgy connection/wire.

Otherwise, if (?) the cause is a fault with the ignition switch (internal mechanism) electrical contacts, that could be due to 'age'/wear.
Complete (aftermarket, non-oem) lock and key sets are available at reasonable (?) prices, e.g.,....
From China at under £40 delivered to UK.
From Italy at £116 delivered to UK

See pages 21-20 & 21-21 here...

If you get one of those Lock and Key sets and the Key that comes with it has the cavity for the HISS transponder chip you can simply take the chip from your existing key and place it in there.
I bought 'better quality' (stronger material) key and did just that...

This reminds me of something that happened to me many years ago. Picture the scene....summers evening finished work at half nine,, my commute then was up the lovely Lune Valley and I was heading home to get to the local before closing, the village before mine had a pub on a corner which was popular with bikers, I was on a GSX750 with a Harris 4-1 system. passing the pub and accelerating out of the village towards an awkward left over a bridge when suddenly the bikes electrics cut out, power, lights everything, I hit the brakes whilst lifting the smoked visor and trying to follow the white line and all the time waiting for the inevitable collision with the bridge parapet. I came to a stop in the middle of the road, fiddled with the ignition key and power was restored, believe me my hands were shaking as I downed my first pint.
PS It never happened again.
