Headlights not working

Richard1969 · 09-13-2016, 10:16 AM

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.

Just thought I'd try to clarify things.....The pass switch lights up the bulb. There is only one earth in th headlight bulb, so if it works with the pass switch, then the earth is ok. The pass switch and hi beam position in the switch use the same cable from the switch to the bulb, so, if the pass switch lights the bulb, then the cable between switch and bulb is ok. As the pass switch works, we know that there is power to the switch..........So...... power to the switch, power from the switch to the bulb, and a good earth. The only thing it could be is the switch itself.

How's it going? Have you sorted it yet?

Yes thanks got a second hand wiring loom in the end and seems to have sorted the problem. Just getting her MOT'd Tuesday. So all good can then register her in the UK. Thanks for the help much appreciated.

It's a long time since I rode in the UK. MOTs weren't required for bikes then. Is it the same as cars? Third birthday, then every year? Here in Spain, for cars it's fourth birthday, then every two years up to tenth birthday, then every year after that, but with bikes it's fourth birthday, then every two years forever.
