Electrical Problems - Help Needed

[Piggin]

I have had this bike a year (2001 S4) and have had nothing but problems with it, its great:cry:

Took the bike for its MOT on Saturday and it failed. The bike was fine prior to setting off as I tested all the lights, indicators etc.

Problem - When I turn the key to start the bike, sometimes the lights, horn, brake lights etc will work and others times nothing works but the bike will start.

I have checked the fuses they all seem fine and I have replaced a coroded connector on the back light.

Any ideas would be greatly appreciated.

A check of the earths maybe?

As Katana says, check the earth connection. It's under the battery holder on my M900, and looked lovely and rusted and white. A bit of cleaning and all the electrickery components came back on and now all is well :D

Thanks for the info guys, I will have a look tonight and see what I can do. Unfortunately not much of a bike DIYer but I do try.
I may come back to the thread if that doesn't work as no doubt a dealer would charge the EARTH! to find the fault. Thanks again.
