Merry Christmas to you all, hope u had a nice day yesterday.
Right I'm having a bit of an issue with my charging voltages.
Iv currently fitted a new battery and also changed the rectifier to a mosfet type from r1/r6/Fjr1300.
I'm getting figures of 15.2v at idle and rise to 15.4v at high revs.
I have made my own loom using the 3 yellows direct from the stator / oe wiring, red wire straight to positive of the battery from the r/r via a 40a maxi fuse and the green from the r/r to the negative terminal of the battery.
Could these voltages be too high to cook the battery as iv read in the auto data book that 15.5v @ 5000rpm is ideal.
Please help and thanks in advance

Re: Charging issues
Anything above 15V would be a tad excessive

What's the FH serial on the R/R? (FH001?) is it a genuine one or a cheap Chinese copy?
Also is the multimeter reading accurately? Try another for a second check measure.

The reg rec is a Fh012aa which I purchased off ebay but its a copy.
Iv grabbed another multimeter from work just now so I'm gonna test it again tomorrow
Re: Charging issues
"but its a copy."
If a Chinese dodgy copy then you're likely worse off than before you started.
Consider this FH020
