Hi All:

I spent the evening trolling around motorcycle forums when I came across a post where a fireblade owner earthed his rectifier to the chassis. He said this decreased the heat in the three yellow wires between the blade stator and rectifier. I didn't do this, but the connection between the rectifier and the stator does get very, very hot.

Do you blade owner earth your rectifier?

--Thanks, Chris

The rectifier is always best when given some sort of "Heat Sink". IIRC the original Honda rectifier has small copper/brass bushes in the fixing holes which suggest to me that the unit should be earthed.

Our's was mounted up in front of the engine right into the nose cone on a large aluminium plate. Obviously this was earthed...

there is more to this than meets the eye;

depending on the elctrical circuit and what was actually done, having a better earth i.e. lower resistance could well mean tha more current would flow so that would have the opppostive effect,

I suspect, as ^^^^ said, slapping the unit on some chunky metal lowers its temperature as it acts as a heatsink.

but its better for leaving the heat where it needs to be also the current is limited true the engine revs...

i think the rectifier just heats up the wires if not good heatsinked its amazing

while soldering 2 wires the wires also become quet hot altough you only apply heat on the conection..

Sow better heatsink is always less trouble..

but iīm sute it isnīt use as a ground ground...
