Electric problem
bomber:
DS doesn't have them, think it is easily available to buy from electric shops so they can't be bothered :)
I pasted a link to website which have a cables which look's similar, thought some body might have bought replacement from them.
Is this specification correct? "16mm2 cables with crimped on 8mm rings"
I thought they where 6mm rings, since I'm not going to be in garage today thought I pick one of you guys "brains"
As for cleaning connectors, it is easy enough with a "male parts" as they ehmm stucking out :)
But how to get to the bits inside the white blocks?? think there must be a better way then a sand paper on a ice cream stick... :-[

Hi Bomber,
Yup, you've got good corrosion by the rectifier... a dismantle & clean (no short cuts that I know of) the only way to go. The burned hole is likely due a connection beginning to fail (you'll likely see the copper wires badly corroded) in which case a 'remanufacture' of that loom piece may honestly save the false economy of a fingers crossed bodge. It'll be more obvious with the boot off.... that red/white is too short to cut-back and you might have to solder in a splice, or replace the red/white all the way back to the loom plug. (or find a second hand one ebay?)
Honestly not a drama replacing a wire, though you do want to have a new spade connector up-front & a decent crimper - unlikely money wasted as will be used many times over. The loom plug pin will withdraw by poking a mini blade screwdriver etc into the plug & releasing the barb which holds that connector pin in place. (you will have to re-use / solder to this pin so go carefully here)
As for the battery +ve lead.... buy a new one and as your starter motor draws approx 120Amps at load ensure it meets this rating minimum - ie choose say 135A or 170A. The lugs will depend upon your battery connection.... mine are 6mm bolts. Bare back enough copper to go all the way into the lug & then flood with solder & this should do the trick.
Try shopping here..

Good luck,

PS - I might know of a seller who has the rectifier + loom + connector plug for a 400F. You'll have to do the homework but if the same for your bike may save hassle. Won't publish it here but if interested pm me & I'll send you his link.

Thank you Lobo but will try to fix my loom rather then replace it, it might take me some time but hope I will be able to understand it better this way.
I had a quick look and there are few other issues...
My head lamp is H4 60/55W and since it is draining my battery I'm thinking to replace it with H4 45/45w it will still be 10W more then Honda intended but it should work right, is any one using 45/45?
Also, where should be negative cable from battery be fixed to? frame right, can any one of you nice people send me a picture of where it should be? I suspect on my bike it is not in right place as it should be fixed to the bear metal of the frame, not thru bushing of some sort.
Another thing is I have strange cable I suppose earth going form negative terminal all the way to ignition coil, it looks like a recent upgrade...
Again thank you very much for comments.
Trigger:
Just sent you a PM that should sort your problem out.
Bryanj:
Earth cable should go to the large rear engine mounting boly outside the removeable bracket BUT there should be NO paint on the bracket whete it touches the engine OR where the cable sits.
There ought to be an earth wire in the loom goinrg to the coil brackets BUT also there should be no paint where the bracket attaches
