Massive long shot this, but does anyone happen to know the difference between Yamaha rect/regs 4XY-81960-00 and 6D3-81960-00. 4XY is the original part on the Ten, but I was forced to replace mine with a 6D3 which I got from a Yamaha Marine dealer. They look identical and I assumed the different part numbers were simply due to a different parts catalogue for marine products.

I only ask as I'm trying to source another here in India (yes, this is the first bike I have ever felt the need to carry a reg/rect in the spares box!), and the 6D3 is twice the price of the 4XY which suggests they may be a different spec.

Also, the (second) failed reg/rect has a blackened pin (front left as you look at the finned side of the unit), which suggests to me a loose connection. Is this likely to be the cause of the failure? The connector was fully clipped on and rain/water ingress has not been a factor in the failure. There doesn't appear to be any damage/failure of the connector itself.

Any ideas how I can try and prevent this from happening again? There is very little chance of getting a replacement connector/loom.

Cheers, JD
