CB400 Sf headlight relay.

Post by Kenbob999 » Wed May 27, 2015 5:07 pm

Hi,
I've got a cb400 sf and there is a problem with the headlight. It's a system where the headlight comes on when the engine is started (or so I beieve, there's no switch)
Where would I find this?
Is it part of the ECU unit?
Cheers,
Chris

They are a grey import and are all like that I think the headlight goes out on engaging the starter motor but will come on immediately it fires up.

I have 3 imports of different marques and as superjack says they all switch off the light when the starter is pressed. what is the problem with your light.

Hi all,

Basically, nothing.
The wires have ZERO power coming to them at all. Changed the switch gear and nothing, bought a new loom, that's next
