Headlights not working

Richard1969 · 09-09-2016, 05:56 PM

Looking for a bit of help my headlights are intermitent. I have traced the wiring back through and cannot see anything amiss. Looking at some of the other threads on here it says to check the main ground. Is that talking about the battery earth that goes to the engine block. I have just found a problem I had with the indicator only working one side was a wire into the block under the tank. Messing with the other block there which the headlight wires go into makes no difference. The headlight comes on when I press the pass switch.

Does the headlight not work in Hi and Low position on the switch or just one of them? The pass switch powers up Hi beam. Maybe your Low beam is burnt out.

It is definitely electrical as it works periodically. I have cleaned all the contact points at the switch end and tried to follow the wiring back along. The light does not work in the low or high beam but the high beam comes on with the pass switch. Just a little stumped on this one.

Have you checked the wiring in the actual headlight bucket?

A Sylvania SilverStar bulb will give you a bit better lighting but be fore warned their life expectancy is a little shorter with the vibes from the GZ. However they will seemingly last forever in a cage or a bike with little vibration.

Yes I have the headlight out and the bucket wiring looks in good order. I may after reading some of the other threads on this subject strip the casing back to check for breaks in the loom. I was after some advice as to where the earth terminates, it looks like it goes all the way to the battery then the main earth.

Yes, the earth goes back to the battery, but it picks up all the other earths on the way, so there are lots of connectors to check. The first connector goes to the front indicators, so, if these are working, the earth should be ok right back to the battery. The pass switch feeds a contact in the light switch, so power is getting to the switch block (to a separate contact), then to the headlight. This shows that live and earth are both ok in the headlight. I'd still put my money on it being a problem with the other contacts in the switch.
