Hi Guys,

I'll explain the story regarding my SV650 Curvy to give you a better idea of my issue.

So I purchased the bike about a year ago from a reliable friend who had taken care of this SV for years. Only 22,000 Miles on her now.

Anyway my SV had a MOSFET Reg/Rec from a CBR1000. And a few weeks ago, I lost power to my bike mid journey. Managed to get it bump started.

That night, I took the bike to my highly experienced friend to check it out. We found that all wiring coming from the Reg/Rec had melted and burnt out really quite bad.

I am slightly concerned that this has happened since I installed my brand new oxford heated grips. They draw under 4 amps, are wired directly to the battery with a relay, so surely this should cause no problems? Headlights are both 55W and rarely run them at high beam. and the rest of my lights are all high quality LED's.

We proceeded to test voltage output from the alternator/stator which put out a good 80 Volts across all three of the yellow alternator output wires at 5,000RPM. So the alternator is just fine.

Next, we checked the Reg/Rec itself. My friend tested it, and said it's looking likely that it is the Reg/Rec. We tested the charging voltage of the battery, which was around 13.2-13.5V at 5,000RPM.

So I purchased another Brand new Reg/Rec. Forgotten the Brand but when researched, It was highly rated on most forums.

We renewed the wiring and installed the new Reg/Rec and is now reading a charge voltage of 14.2-14.5V at 5,000 RPM. Doesn't go above this at any RPM.

However, Here's the bit that worries me. Before my first Reg/Rec went, I noticed my grips were intermittently going into power saving mode (Detects low battery voltage) for a few weeks before the wires melted at the Reg/Rec.

Since installing the new Reg/Rec, Battery has been charging perfectly and consistently as I have been closely monitoring it. But now, two weeks of use on the new Reg/Rec. I am noticing my grips are starting to power save again. This of course is now worrying me as this was what happened before my first reg/rec failure and I just spent £80 on a new Reg/Rec.

Now, I'm not saying this is a sure issue. But Obviously I would rather catch the problem before I get another wire melt, or another damaged Reg/Rec.

Any advise to help prevent another problem would be appreciated, and thank you for your time to read this, I just thought more detail is best.

If you need any more info, let me know.

Kind Regards,

Jordan.
