Voltage regulator rectifier

Hi guys, I got in my GTR 1400 reg 2011, voltage regulator rectifier no FH012BA can I use a FH020BA as replacement? Is any difference between them ? Thanks

The Kawasaki part number for the Rec/Reg is 21066 21066-0771 REGULATOR-VOLTAGE for all years from 2008 to 2017. That is the FH012BA.

I believe the FH020BA is for the ZZR1400/ZX14.
No idea if they are interchangeable or not.

Thank you for advice, I found that part and genuine cost about £230. Seen a lot of options on eBay with price range £50-100. Is any sense to buy the cheaper replacement? Or only the genuine Kawasaki? Is quite big difference in price, anyone tried any trusted replacement brand which works fine for longer time and not burn anything 😜 ?

If an OEM item has burned out, I'd give the pattern a go

FH012BA is higher current rated for the 41 amp gtr1400 alternator.
FH020BA is for the zzr1400 35 amp alternator so stick with the FH012BA either "genuine" one (Kawasaki don't make them they buy them in) or the aftermarket one which is probably made by the people who supply the same part to Kawasaki and Suzuki.
Clean all corrosion off the plate it mounts on and copper slip the mating surfaces to help heat dissipation.
