Lights flickering

Post by taavikaarid » Mon Jul 03, 2017 7:03 am

Hey,

I wonder if there is anyone who can pinpoint my problem. While riding all the lights (including the dash) become bright for a few seconds and then return to normal and sometimes they dim below normal level too. It fluctuates all the time but especially when at higher rmp.

Could it be the voltage regulator?

Thanks!

Sounds like the Regulator / Rectifier.

DO you have a multimeter or voltmeter? You can check the voltage at the battery while revving the engine briefly and if you see more than 15, you have a bad regulator.

Indeed, the RR has failed. It boiled my battery last night and voltmeter says that's no good.

I started to look a new one and it appears that this is actually the trickiest part. My failed regulator has 47X-A1 / SH569-12 / 8.D.3 written on it. As far as I can tell, this item is actually a stock item of FZR600 (mine is XJ600 51J 3KM1). I have found a version with code 47X-A2 / SH569-12, but I'm not sure if it actually fits.

So, which RR would fit on my oldie or do you perhaps know the right code to use for my expedition?

Thanks,

Bought this one: http://www.ebay.co.uk/itm/NEW-REGULATOR ... 2749.l2649

Works well on my 51J.
