Main beam not working

[roman emperor]

Help, i,m at a loss, kawasaki er6f 2009, main beam does not come on however the bulb is good, there is 12.35 volts at the bulb holder when not connected with engine running, dash indicator light shows when not connected to bulb but as soon as you connect bulb to holder the indicator light goes out. Any help would be much appreciated.

MY first thing to do would be clean the switch with contact cleaner.

how do you know the bulb is good?

plus check fuses .

So have you actually run a current through both high and low beam filaments in order to determine that this bulb ( lamp ) is " Good " ?

I took the OP at their word when they said bulb was good.

Check there's no corrosion in the bulb holder. It might be shorting to earth when the bulb is installed. I'd try a spare bulb just in case there's an internal fault with the bulb. I've had bulbs test ok with a multimeter but still play up when installed.

I have tried new bulb and swapped the dip bulb with high beam (all work) taken switch apart and checked and cleaned all contacts, cleaned lamp holder, put bulb into holder and earthed directly to ground, still no luck, changed relay and no different. ?

yeah .. take bike to mechanically competent person ....

Not all mechanics are good with electrical systems.

Take the bike to an electrically competent person.

Become an electrically competent person .

It sounds to me like there could be a break in the wire somewhere or a bad connection

There may be enough strands/connection to show a voltage but not enough to carry the current

[Bender]

What voltage do you get on supply to bulb with bulb connected and on, even though it's not illuminated?

If it drops voltage trace back and find where you have a good supply, you could try a temp earth feed to see if it's an earth problem

I had this with our old caravan lights. 12v everywhere but nothing worked. Turns out it was corrosion within the cables. They showed voltage but hardly any current was getting through.

Thanks for all the replies, it turns out as stated by Mississippi Bullfrog it is corroded wires that caused the problem,
