Sprint GT Rectifier/regulator

I've been having some poor starting issues when the bike gets hot after a long run. Seems as thought the battery has lost charge. I wondered if it may be the rectifier getting hot - this has confirmed by a few members of the club who had the same issues with rectifiers failing when hot. I took off the fairing and saw that the rectifier is a huge affair and touches the top coolant pipe, and is surrounded by foam on the inside of the fairing. I don't know who at Triumph thought this was a good idea. I looked at the Sprit parts pictures and Triumph wanted over £300 for one!!! I eventually got one for about £20 shipped direct form Ali Express in China. It is slightly smaller, but does not now touch the coolant pipe. Anyway, going to give an extended test over next few weeks.

The point of this post was just to give anyone a "heads-up" if they are suffering the same.

 

here you go:

However, please note that I am just an enthusiastic amateur and I am not recommending this. If you do purchase and use, it must be at your own risk. I also have no connection to Ali Express.

 

I do think my next move must be to move it to somewhere that the heat can dissipate - such as under the headstock. Phase 2 of the project!

 

I've got the Sprint GT - the rectifier has been moved to the left side (I guess they had so many failures on the Sprint ST that they had to do something). However, the location meant that the rectifier was actually touching the top coolant hose, and was tucked into the fairing, Crap design. I'm going to try and move it around the headstock area.
