Any one used the Mosfet RM30505H?

Maybe it's been covered, or it's in the service manual, but I've not run across a good instruction for testing the Reg/Rec itself. Usually it comes down to battery and stator testing and if those are pass then it's the R/R. Take a look at Roadster Cycle's page of help videos. He's got a simple and informative how-to on it. I even figured it out and was able to learn a new setting on my multi-meter! http://roadstercycle.com/Roadstercycle.com Videos.htm

Charging system troubles are usually blamed on the reg/rec or battery. Others, thankfully few, have fingered the alternator. On my bike the problem was a failed starter relay connector. It had overheated, probably due to corrosion. That meant an open circuit between the output reg/rec and the battery. So, if your bike's battery keeps going flat check this connection before buying a new battery or reg/rec. It could save you $$$.

This connector links the alternator 3-phase to the reg/rec. And this one has overheated a bit, and my money is on corrosion being the culprit.© Lorne Black

This is the starter relay connector on my '92 VFR750 and it had overheated and failed. Charging current from the reg/rec goes through it en route to the battery, so when it failed my battery kept discharging. I didn't find this little devil till after replacing the reg/rec and the battery. It is possible that the reg/rec was outputting too high a voltage but, imnsho, the fault was due to corrosion.© Lorne Black
