What now?...electrics
 

grr having an electrics issue with my bike.
Came to use it last sunday and it was completely dead would not start, charged it for 2 hours and it's been fine up until today. Only thing I have noticed is the headlight/indicators dim when the brake light is activated. Had a half hour ride today pulled up for an hour or so, started it up ( a couple of times as I was testing something) then rode 20 minutes home got to a corner applied the front brake and the whole bike jerked the mileometer turned off and the rev counter soared, pretty sure the speedometer pin had gone to 0 too. Completely died. Pulled in tried to start it up but it just didn't have the power to turn over. Switch everything off, gave it 10 seconds and tried turning it on with the lights off and it started up and I was on my way. Got to my road thoguht I'd test something, put the lights on as soon as I touched the brake the bike started dieing again, digital display/mileometer turned off, rev counter jumped again etc. Pulled into my drive, switched off and tried to start again but had no power - just struggled.

Any ideas? reg/rec? bad earth?

sounds like the regulator to me

Check the charging system, but a bad earth can give lots of wierdness.

cheers for the replies.
right I've acquired a multimeter how can I check the charging. A certain voltage across the battery at a certain rpm?

Re: What now?...electrics
 

Should have 13.5 - 14.5V at 5000rpm with the headlights on.

cheers will pop out and try it now

Re: What now?...electrics
 

it ain't charging. keeps at a steady 12v whatever happens.
any clues?

Check your stator now

Sorry, how do you mean check it?
I'm a little slow at the best of times but electrics are a no go for me.
