Title: No power to indicators or rear brake light switch on XBR
Post by: mthee on August 29, 2019, 10:43:57 AM

MoT is tomorrow!
I've been on this lovely electrical problem yesterday and need help. Symptoms as per the title.
There is power to all fuses, none are blown.
Looking at the diagram, there is a common power wire, W/G, going from fuse 4 to horn (works fine) turn signal relay and rear brake light switch.
Is the sequence - battery, fuse box, relay, switches and bulb holders?

Any advice gratefully received

Hi there

I'm sorry I can't help with the sequence but can reflect back a couple of things that you must have thought of.

Are you sure the power to the horn is actually coming from a common power source? Have you had a meter across the W/G wire to make sure it is delivering 12 volts? Is the indicator relay at all suspect? Can you run a separate power wire to the indicators or brake light switch to check if they work?

Hope this helps in some way.

Ian

This is an easy one.... sack the indicators. Just stick your arms out when turning left or right 🤣🤣

No seriously Matt, sorry I can't help out, electrics being my weak point. Hope you get it sorted.  Best of luck with the MOT🤞🤞
Cheers, Michael

Thanks for the suggestions! Turned out to be a frayed wire, W/G. That'll teach me to smooth back the frame at  all my ground off bracket points before offering up the new tank repeatedly!
It's in with the local MoT station, so hopefully, I'll be the full ticket by this afternoon!!!

He's too busy riding it to come and do a keyboard tap dance!  ;D

All the best, Bill
