i have put a new battery on my bike but its still dying after a few miles so have gone down the route of replacing the reg/rec,is this a easy part to fit? or would i be better off letting a grage to do it? i do most of the services,disc/pads but not sure when it comes to electrics anything to be careful of? cheers
What year? Few pointers here http://1000rr.co.uk/maintenance/19780.htm my alternator burnt out known fault on rr4 / rr7
thanks for the reply dave, my appologies but its not on a blade, my bike did have a recall on the reg/rec but i have put a few miles on it since
Charging System Test. 1) Make sure the battery is fully charged, and tests OK. Take it to your local batteries place and have it discharge tested. After charging a bad cell in a battery can give you 12 volts, but fail under load. When in doubt, replace it. 2) Start the bike. Take your electrical meter set to DC volts and measure across the terminals on the battery. With the bike running it should be somewhere between 12 and 13 volts at idle. 3) Rev the engine, and measure the voltage at 4000 - 5000 RPM. It should climb to 13.9-15 V. If it goes over 15V, your regulator rectifier is cooking the battery. Replace it. If it doesn't climb, it's either your stator or your RR; you'll have to follow the Stator Testing Procedure below to determine which it is. Stator Testing Procedure This is probably the easiest, most reliable test: Always start charging system tests with a fully charged battery. 1) The stator will have 3 wires coming out of it. Usually they're Yellow. Locate where they connect to the Regulator/Rectifier, and disconnect it. 2) Start the bike. 3) Take an electrical meter, set it to AC Volts. Measure voltage between any 2 of the wires. You should get 15+ volts across them at idle, and when you rev up the bike, it should quickly climb to anywhere from 40 to 80 volts. 4) Check all possible combinations. If you don't get voltage, or get low/ none, the stator is bad. Every other test you can do (continuity to ground, resistance between the pins, etc.) won't answer the question: Am I getting output from the stator? If you're getting output from the stator, and the connectors look good, your Regulator/Rectifier is most likely unwell. Good Luck, Mike.
Question? If the Stator is faulty. Do you change like for like. Or is the flywheel upgrade necessary.
Someone else will know the definitive solution, but I believe the earlier ones had a clearance issue. So changing the whole lot would be the gold standard. I think that was what Honda were doing as a remedy. Mike.
