Hello all, I'm Jim and I have been working on a 71' CB750 K1 as my first project - if anyone is interested you can see it here (shedcustom.worpress.com). I have relatively comfortable finding my way around the mechanical stuff but when it come to electrics I struggle so would really appreciate any help anyone can give - so here's my problem.
I last rode the bike about 6 months ago as I've been working on it over the winter, I have come to start it and there was nothing. I have had the battery on trickle charge over the winter so thought it would be ok. The headlight and brake lights came on but it wouldn't turn over the reading from the battery read about 12.7v but when I turned the ignition on it dropped to 8.6v so thought it may be the battery so I have just replaced it with a new one. It still won't turn over and now only the neutral light will come on the headlights, brake lights horn etc now do not have power and I have tried hooking it up via cable to a car battery to see if that helps - it doesn't still on the neutral light. I read in another thread about bridging the solenoid terminals to see if that works - i got sparks and it turned over - thats as far as i have got - does this make sense to anyone…please?
Thanks
Jim
