Main Beam problem
 

SV650s K3

When I use the 'Pass' button, nothing happens - ie, normal dipped headlight remains on but no main beam.

When I switch the main beam button on, all of the headlights go out.

Tried swapping bulbs but that hasn't sorted it.

Is it likely to be a fuse or switchgear problem?

Need to get it sorted as its MOT time in a few weeks.

Thanks very much for any advice

Re: Main Beam problem
 

Sounds like it may be an earth problem on your main beam make sure all the connection are clean and tight

Have you checked the high-beam circuit's fuse? Might just be blown/loose/non-existant e.t.c.

Re: Main Beam problem
 

High and low beam share their 'earth', so if it were duff neither would work.

Like Matt says; check the fuse, if not that then the problem lies somewhere on the line:
- Yellow wire in left side switchgear to block connector, (after junction dip/pass switch).
- Block connector loom/left side switches.
- Yellow/blue wire from block to fusebox.
- Fusebox connections and holder.
- Yellow wire from fusebox to headlight connector.
- Headlight connector.

Have you a twin filiment bulb? you sure that the highbeam filiment hasnt blown?

Re: Main Beam problem
 

He said he swapped the bulbs, so unless both bulbs highbeam filament has blown then it's not that.
