Charge Rate?? By wildman (Read 1,244 times)

Does anyone know what the charge rate is for a GY6 charging system?? I know for an automobile the charge rate should be at least 13.75 volt, but wondered what is for the GY6 engine...

At medium to high RPMs - check w/ bike on center stand- the charge rate at the battery should read 13.7 to 15.8 volts - over 17v, not good - check regulator, under 13v, also not good, check regulator and stator output

At idle, my gauge reads 12.8 or so, under load, between 13.8 and 14.5. I have not checked it while acrtually riding, just on the center stand and I don't like to hit high RPM's while on teh stand, so 14.5 is about the highest I have seen. Of course I have all my lighting converted to LED so that helps as well.

Jake - yours sounds normal
Rich, my mechanic (he likes to be referred to as a scooter technician) uses a multi meter, and a wired up contraption using a known good regulator. He checks input and output of regulator - but 90% of the time it is the connections - 1st thing to check, if connections are all good, then he plugs in his regulator - if that works (testing at the battery), then we replace regulator., if not, then he checks stator output...I guess we go in order of price to replace,and typical failure. We have had to replace about 12 stators due to grounded out wiring (out of 550+ bikes), but many more regulators...
