Brake light always on

[greywolf]

When you say you removed the brake switches, did you actually unplug the wires from them?

That's a great question. I considered that a given to be what removal means. It may not be the case though. A bad switch will still light the brake light if removed physically from its mounting place but still wired in.

Can the tail light leads be disconnected without disturbing the brake light to see it they're the cause of the problem?

Not without cutting a wire or dis-assembling a connector. See my post from Mon Feb 23, 2015 12:02 pm to see how to troubleshoot the connector.

I will have another look at this over the weekend and see where it takes me.

I have fully removed the rear connector but haven't removed the front one other than from the pressure switch on the reservoir. I have recently added in some k lights via the bigpie unit and added my heated grips so it may be something to do with that.

I did have some issues with chaffing on the LHS under the tank before and fixed that - but I will re check and get all the plastics off first. Thanks for your assistance so far, I'll report back with any results soon.

So I had an auto electrician come out and have a look at the bike. Within about 5 minutes he knew that the cause was a break in the wire somewhere in the harness that was causing an always live to the brake switch. We unconnected all of the connectors, still not joy then through a process of elimination and looking at the condition of the harness saw that it had rubbed through and caused a short.

This was on the LHS next to the fuel pipe where it had been rubbing on the frame. Fixed the wiring (2 had completely shorted together) and Hello presto all working again. Magic.

Thank you to everyone for your offers of help and advice but it lives on for another day.

So if you have any similar problems the LHS wiring loom is a good place to start looking..

Cheers everyone.

Another thought. I think I've seen posts regarding people having areas of the wiring harness chafing on the frame. Has this been considered?

Do I win a prize?

Glad it's sorted!

Prizes all round! Oh goody!

- maybe two have been mashed-together? Or somehow chafed together you should narrow down where the problem is.

Try phoning a few local auto-electricians , who have the skills, experience etc eg http://autoelectrical-crawley.co.uk/ele ... es/1251770 who are mobile as well...(tell them you'll strip all the panels , tank etc off the bike for them before they start!)

Glad you're sorted!
