thats the whole point of a regulator
it allows a maximum charge depending on the state of the battery
up to a point...the charge going in will NOT get higher the faster the alternator turns over (becoz of engine revs)
The regulator works to stop overcharging ..and boiling the battery

.If you are not sure what you are doing i suggest you take it to an auto elec as you could end up doing more damage.
good idea....becoz there are lots of things that can be the cause
the rectifier in the alternator could be acting up
the regulator could be stuck shut or open or shorting
there could be internal resistance in wiring
get someone who know whats what

hth

Yeah, I was hoping to pinpoint the actual problem before taking it somewhere..... Some mechanics will shaft you because they spend 3 hours trying to figure out what is actually wrong.... Usually when I go to a mechanic I like to know exactly what is wrong before I take it...

lectricity mate
can drive a man to drink

even the most qualified guy with a meter can spend time on something like
this..especially if you have to start checking the windings in the alternator
or output levels at certain revs

How do you check the voltage before the reg-rect and what should it read?

Hey Stereo

have you got a copy of the workshop manual ???

in my 00-02 zx6r one its all there step by step in chapter 15 how to check all the charging system

WRONG

Stereo your bike has an ECU system fitted and most home / readily available chargers have been known to "spike" these delicacate electronics. I always disconnect the earth lead when charging a battery

amen to that - cheap chargers don't have spike protection (usually), so any voltage 'spikes' through your charger have the potential to fry your electrics .....

surely there is a downloadable manual *somewhere* out there for this model Spewzie ?? It will have all the specifications for checking the alternator outputs, etc. Without it, you are just flying in the dark......

shouldnt really matter if the bikes not on

but ive never charged a battery with it still connected to the car/bike, and the battery has always charged up (as long as it wasnt fuct) and i never caught the aids or anything

Wasnt me that asked that............ I never charge with my battery in place.....

I think I confused things by asking about charging in place, and Bladeboy answered me

so I should disconnect the leads? this is for my ZZR600 trackbike

I thought I was wrong once but I was mistaken, anyway..been charging bike/car batteries for 30 years, no problems so far, seeing you could not buy a charger that has as many spikes than your normal electrical charging system that comes with your bike, I think you will be right. ECU or not.

Charging with Battery connected in place is OK, i know that as a FACT

Of course, don't try to turn the ignition on

I disagree... all manuals say not to do it....... They dont make that crap up usually....
