Evil Twin
Participantok
got a z750 twin
it was KK and hoggys and beefs once upon a time
our lass’s bike now
stripped and rebuilt and rewired by me
when we got the evil twin she wasnt running
big wireing issues
ok my questions
can some1 please
when they have the time
tell me what readings theyre getting from the
ac generator
rectifier
regulator
i have tested them
mmmm
am getting readings
nothing points to anything being wrong in these parts
but
i cant find what readings they should be.
i know if a fault in the circuit/diode then it would display it in the multi meter,
which is analogue dial not digital by the way
every thing is wired/working as it should be (had absol nothing working wireing wise when we got the evil twin lol)
ive just got the condensor to test,
bought a new coil/tested it,its good
plug caps are correct non resistor and reading a strong 5ohms
baffled isnt the word im looking at useing lol
frustrating,but with a smile,i aint shy at asking for help but it is rare,stubborn pride lol,
so,any1 that can spare the time to reveal the info i need that would be a great great help.6th September 2015 at 11:04 am #12839lonesome
ParticipantNot sure if you’re talking about readings when it’s running or stopped. You can’t really take resistance readings across windings etc because the resistance is so low that everything looks like a short circuit to a multimeter. I’m not really sure about the regulator wiring but across the rectifier section you should be looking at about 1.4V between any 2 wires. I think the whole thing is one package tho, so a multimeter will be useless.
When it’s running all you can really hope for is 14.4V across a charged battery at 2000rpm or so. Above 14.8 and you’ll fry the battery so you’ll need a new regulator. Less than 13.2V on even a flat battery and the fault could be anywhere in the system, but is much more likely to be the wiring. I’ll see if I can get some readings off of mine later, but since it’s running at 15.3V at the moment it might not be a good guide.
Oh, it might be a good idea to check the -ve line resistance between the battery and wherever you connect the black multimeter lead. Nothing screws up vehicle electrics like a dodgy earth.

Participantthanks lonesome
lol i replied to this yesterday
sprnt ten mins writing all the figures i got from the regulator
rectifier
ac generator
from the multi meter
the bikes a non starter at the min lonesome,so all tests done with parts off the bike not connected to a power source
grrrrr
i didnt press the feckin submit button.
doh
will add later ok -
