battery keeps going flat bike dies

[bikerbiffo]

hi got a problem with my sons 1993 super four
charge battery but keeps going flat..how do it test the regulator/rectifier ? what output should it put out
theres no rise in current when engine running
does any one have a wiring circuit for this bike.?that i could copy.
will any honda rectifiers work?
or is there any dodgy faultys on this model..or will i have to bite the bullet for a new rectifier

cheers

great..thanks for that.
just print it off
hopefully i'll have a go tommorow
couple mugs of tea should do the trick
got to get it ready for bmf on sunday
if the rectifiers at fault i'll put it in my pocket and try and match it on the auto jumble sunday


ps: i'd still like a wiring diagram if anybody out hters got one

cheers

thanks for the advice

even dowm
nloaded a cb1 manual with fault finding info aswell

so far my testing has resulted in a short circuit of the negative side of rectifier..(a diodes gone down)

looking to replace this but boy do they know how to charge for a rectifier..

will look around and try and get one cheaper than the 70 quid quoted on ebay.
loooks like numerous bikes fit.including cb500's cbr600,fireblades
so should be plenty available..

thanks again

id suggest due to the fail rate of these reg/recs on most hondas of the period yer probs better getting new not s/h tho m8.
i got mine from wemoto but i think there is cheaper about.. pretty sure alexibrow got one fair cheap but cant remember where from

or you could wire in your own diode from maplins about 30pence

hi .
priced the maplin route
cost of £4 for the large diodes required..but needed to go to 2 shops for them..that was plan c
plan a this morning got up and went to bmf and rumaged on the auto jumble..
got one off a cbr600(1999. £20..then continued to rumage and got one off a cb1 for £5..
the cb1 isn't the correct number but it's ok for a spare
..fitted to bike as soon as got home..works fine..

there were a couple of complete sf400 exhaust systems on there but no body work ..

so sorted..
thanks for the replies and advice this is much apreciated
