thanks for the help guys, will do some more testing this evening and let you know the results, will also let you know what battery is on it as i can't remember.
my mate has one of them, i'll see if i can borrow it.
yes its an older battery, prior to fitting it was on an optimate for quite a while but a good state of charge.
May be a dumb question, byt doea anyone know what the acceptable charging voltages are for a 600 srad?
On idle mine is 14.3V and with the revs up it 12.8V
Thank you in advance.
