Evening
Noticed over a while that my 04 fazer has been more and more difficult to start fired but was spinning over slower, anyway other week wouldnt fire turned out battery was low so I put it on charge. Was odd as ive been using the bike and it hasnt been standing around.
Measured the voltage across the battery at 5k revs and the reading was only 13.5v book says it should be 14 to 14.8
And at idle its less than 13v
Know I could keep the bike on a optimate but this is a pain, plus at this time of year ill be needing my heated grips and heated kit applying extra strain on electrics
being a ex aprillia owner thought it was the stator but the readings from the stator all check out resistance and ac voltage
Mate has a fazer so I borrowed his rectifier to see is that made and difference it didn't and was getting the same 13.5v across the battery at 5k
Had the white connectors in the charging circuit apart and cleaned
Starter relay out cleaned and the battery terminals/conectors cleaned too plus the earth next to the starter motor
Borrowed mates battery
Still no joy
I found a thread on here called "voltage drop mod" which recommended running another wire from the + output on the rectifier to the battery ive also tried this with no success
Ive also got a problem with the rear lights when either indicator is in use the rear light dims slightly, doesnt matter if the engine is running or not it still dims
Ive checked for corrosion and the connectors all look good. Ive measured the volts at the rear light and it drops by . 5v when the indicator flashes.
I ran a temporary wire direct from the battery to the rear light and this stopped the rear light dimming.
Dont think these issues are related but never know
I keep thinking its a earth issue but other the one off the battery dont think theres another to find!
Thanks
