Battery issue?
![Post Post](./styles/redsteel/imageset/icon_post_target.gif)
hi, need help with a battery problem please.
Over the winter I fitted a new mosfet style reg/rec to my sp1, I tested the voltage at the battery after and it was putting out 14.5 at idle and the same at 4000 rpm I took it that this was ok, it might be worth mentioning the battery was disconnected for a few weeks prior to this point.
I have since ridden the bike several times adding up to about 5 hours in total no problems at all.
Today I go for a 45min ride and on way home call in at parents, went to leave and the battery was flat.
I put it on an optimate charger for a few hours and it brought the battery back to 12.8v and this was enough to start the bike.
I then tested the reg/rec voltage output at the battery and now it is putting out 12.3 at idle and 12.7 at 4000 rpm.
Is this enough output from the reg/rec?
would a knackered battery cause the reg/rec output to be lower than before?
Battery is a YUASA YTZ12S and is about 2.5 years old and is always on a optimate trickle charger.
Any help would be much appreciated.
Cheers
