Hi, I am getting back to the Fazer now after a few years of working on my Gpz. One problem it has always had is that when the headlights are on & you switch to full beam or press the passing button, the lcd on the dash goes off for a second then all lights flash as though the ignition has been just turned on. So far I have wiggled all of the connectors, tested the 2 headlight relays as per the Haynes manual and they seem good. The bulbs are the correct wattage. The other thing that is strange is if I unplug 1 bulb then it is fine, doesn’t matter which side I undo. Has anyone had this problem before or got any ideas as to what I can check next? Nick.

Check the connectors in the black box under the tank.

....yes I wiggled them, but will have a better look & see if there is any corrosion. I think I may have missed one on the left hand side of the fairing.

...thanks, getting there. All connectors were fine, used contact cleaner & acf50 anyway. I ran a -ve straight from the battery to bulbs, relays & connectors. When I ran it to the connector in the black box for the right hand switch block the problem no longer happens when switching from dipped to full. I had the same result from both sides of the connector so know the connector isn’t the problem I will work back & if I can’t find a problem I will run a wire from the battery to the connector. Passing button still causes a problem but will work on that afterwards.

With engine running or not?
My foxeye without engine running does that. But it's fine with engine on.
Led bulbs or normal halogen? i presumed its a battery thing and if it's not being charged it doesn't like the extra load.
If yours does it with engine on, what sort of voltage you got at the battery?

Thanks for your reply. I tried it only with engine off. I have the whole front of the bike dissasembled at the moment, can't try it now with engine running. I just got the bike a couple of weeks ago and have no idea what bulbs are in there but from the illumination they produce I suspect halogen. And yes it acts like the load gets too high for the battery to cope. However the battery was fully charged when I tried it. But it isn't new so could be worn out I will have to test the battery for capacity.

By engine running you mean idling or higher rpms?

Finally I have the bike assembled and was able to try it with the engine running. When I use the full beams it does it only randomly, maybe 2 times out of 10. But when I use the passing button it does it all the time. However I didn't get a chance to check the battery yet. Only thing I noticed is that when I put it on the charger it starts to charge and in 5 seconds it switches to maintenance / trickle charge. So I guess the battery isn't holding the charge. Interesting thing is I started the bike with it a couple times and it always starts on first try without any trouble ... is it possible that the starter pulls less from the battery than the high beam halogens?

I had this the other day, turned out I needed a new battery, the old battery was a good 7 years old and getting tired. Change of battery helped me.
